D-Wave Riding The Dual-Rail For Its Gate-Model Quantum Ambitions
Jeff Burt
Published Wed 10 Jun 2026 // 05:05 UTC
D-Wave is something of an anomaly in a quantum computing industry. While companies ranging from hyperscalers like Microsoft, Google, and Amazon Web Services to traditional enterprise system makers like IBM, Dell Technologies, Cisco Systems, and Hewlett Packard Enterprise are trying to get some revenue, and pure-play vendors, software and algorithm specialists, and cybersecurity firms are establishing themselves and looking toward the near future. But D-Wave has a growing business already in place that is bringing in millions of dollars.
Company executives years ago embraced annealing quantum technology as the shortest path to get to market, and initially made its Advantage and then Advantage2 quantum system accessible through its Leap quantum cloud service. Early last year, the vendor began selling systems to organizations, like Jülich Supercomputing Centre at Forschungszentrum Jülich (FZJ) in Germany, to deploy on-site. More recently, Florida Atlantic University (FAU) agreed to buy a 5,000-qubit Advantage system for $20 million.
It seems to be working. In the first quarter, this year, D-Wave showed closed bookings of $33.4 million, a 1,994 percent year-over-year jump and a 149 percent increase over the previous quarter. Included in all of that was not only the deal with FAU but a two-year, $10 million quantum computing-as-a-service deal with a Fortune 100 company.
Banging The Gate-Model Drum
More recently, D-Wave has been making more noise around its dual-platform strategy, in particular its plans for gate-model quantum systems leveraging the superconducting modality that others like IBM, Google, and IonQ favor. The company made a significant move in that direction when it closed its $550 million deal for ten-year-old Quantum Circuits and its dual-rail error correction technology.
As we wrote earlier this year, the dual-rail qubit architecture embeds error detection directly into the qubits, which D-Wave executives say not only improves the quality of the qubits themselves but means that a logical qubit could be created with fewer physical qubits, which should accelerate the development of fault-tolerant quantum systems. While other vendors are focusing on the number of qubits, D-Wave is aiming to reduce errors at the hardware level by embedding error correction onto the qubits themselves to errors can be found during computation at the single-qubit level.
The Dual-Rail Way
This way, the dual-rail qubits can identity about 90 percent of errors has they pop up, so fewer physical qubits are needed. D-Wave executives also boast of reaching – with error detection – 99.9 percent two-qubit fidelities, so physical errors occur about once in every 1,000 operations. The company is leaning on the Lambda metric for measuring how quickly a computer's errors decrease as more error-correction capabilities are added. According to D-Wave, the norm for most quantum companies is a value of 2, which means each error correction cuts the number of errors by half. D-Wave is looking at a Lambda value of 10, which executives say will reduce errors more quickly by a factor of 10X for each increment, which will lead to fault-tolerant quantum computing that needs significantly fewer physical qubits.
The dual-rail technology dovetails well with D-Wave’s superconducting expertise and its desire to manufacture the systems at scale, according to D-Wave chief development officer Trevor Lanting.
“We saw an immense amount of synergy between this core qubit technology, which really we see as game-changing because it really shrinks the physical requirements to get the full tolerance, but it doesn't take us in a 90-degree direction,” Lanting tells The Next Platform. “This is parallel to the direction we're going with both our annealing and our demo architectures, which is to use superconducting devices to build out these quantum computing systems.”
An Expanded Timeline
With the merger complete, D-Wave is rolling out an expanded timeline for its gate-model systems. When the deal was announced in January, D-Wave laid out a partial timeline that included the general availability of a 17-qubit, dual-rail transmon-based system this year, a 49-qubit system next year, and 181-quibit quantum computer in 2028. The system will deliver 2,000-fold error reduction factor over the physical error rate and will be the blueprint for scalable fault-tolerant architectures. The company also will complete the design for a 1,000-qubit that year.
Earlier this month, D-Wave announced that in 2030 it will complete a 10-logical-quibit system that can support the first fault-tolerant algorithms, and two years later will launch a 100-logical-qubit system that will be able to perform more than 1 million operations supporting initial chemistry and quantum AI applications.
Lanting says D-Wave is getting customer interest in the promise of post-NISQ (Noisy Intermediate-Scale Quantum) systems “the ability to do error correction and then build your software stack on top of that. On the near-term path, getting to that 100 logical-qubit million gate operation point, we're really seeing that as the phase where the gate model systems become commercial across the board. A lot of our customers don't want to wait to 2030 or 2032, because at that point, they will not have developed the expertise on the algorithm side, the expertise in really figuring out how they actually integrate these systems into their industrial workflows.”
Shifting Goalposts
The timeline for these systems becoming performant is speeding up, and organizations are realizing they need to have teams and plans in place for addressing the technology, he says.
“The goalposts are shifting over time in terms of what really is necessary for broad quantum utility, but the best evidence today based on what we know about algorithms and applications is that once you hit that 100 logical-qubit mark and you're able to support that scale of operations, like over a million successful operations, that's really unlocking initial applications, primarily in material simulation and quantum chemistry, that's the point at which we really see this technology transitioning to fully supporting those early commercial workloads,” he says.
D-Wave’s goal is to be a sort of one-stop quantum shop, with both annealing and gate-model quantum systems available. Lanting says there are synergies between the annealing and superconducting efforts, no plans now to directly integrate them.
“Our annealing systems are supporting optimization workloads,” he says. “We're seeing a lot of early signs that they could help with quantum AI applications. There's increasing evidence that gate-model systems just won't be able to attack optimization or a lot of machine learning tasks. ... The annealing systems are not going to be able to address the really juicy quantum chemistry problems and the novel materials discovery problems. That's the sweet spot for gate systems. Depending on the customer and the industry and the use case, they may engage with one or the other, or both.”
Federal Funding For The Effort
As D-Wave moves forward with its plans, it’s likely going to do so with another $100 million on hand. The company was one of several quantum vendors to sign a Letter of Intent (LOI) with the U.S. Commerce Department, which last month announced a $2 billion program being made available to them through the U.S. CHIPS and Science Act in exchange for the federal government taking an equity stake in the company.
D-Wave would use the money to help fund the development of a 100,000-qubit annealing system and 10,000-qubit gate-model computer. Other vendors, including IBM, Quantinuum, Rigetti, and PsiQuantum, sign similar LOIs. However, the money isn’t guaranteed. There is debate whether the investments adhere to the intent of the CHIPS Act, which was passed during the Biden Administration, and whether the U.S. government should be taking stakes in private companies.
Still, it would be welcomed, Lanting says.
“For us there's a couple of things,” he says. “One is this is R&D that is core to our roadmap, core to both our annealing and our gate systems. And this allows us to pull in some timelines for some of the development work that we're planning to do. The second thing, and maybe more importantly, is this is the first time we've got a direct endorsement from the U.S. government as D-Wave for technology development. That endorsement we see as incredibly important.”

D-Wave’s Quantum Supremacy Result StandsMay 26, 2026 2:00 PM
Business Wire Recent classical simulation work represents progress, but does not overturn D-Wave’s peer-reviewed demonstration of beyond-classical quantum simulation D-Wave Quantum Inc. (NYSE: QBTS), (“D-Wave” or the “Company”), the only dual-platform quantum computing company providing both annealing and gate-model systems, software and services, today issued the following response to recent claims that newly published classical simulation work has “overturned” D-Wave’s demonstration of quantum computational supremacy in quantum simulation. The claim that D-Wave’s achievement has been overturned is inaccurate and not supported by the scientific record. D-Wave welcomes advances in classical algorithms, including recent tensor-network work from researchers at the Flatiron Institute and collaborators. Scientific progress in quantum computing depends on rigorous comparison between quantum and classical methods. However, the recently published work does not reproduce the full scope of D-Wave’s peer-reviewed Science result, nor does it solve the hardest problem instances and measurements reported in that work. The only major change in the Flatiron work that has now been published in Science is the addition of large diamond lattice data. This supports the claim that they are using BP-TNS to extract a Kibble-Zurek exponent in a 3D system, but the same criticisms apply as a year ago: they don’t compute the same observables, nor all the geometries, nor the largest size geometries, nor all the couplings computed by D-Wave and its collaborators. In the peer-reviewed Science paper, “Beyond-classical computation in quantum simulation,” D-Wave researchers and collaborators demonstrated beyond-classical computation in the quantum simulation of nonequilibrium magnetic spin dynamics using D-Wave annealing quantum computers. The work studied square, cubic, diamond and biclique topologies and showed that D-Wave quantum processing units produced samples consistent with quantum theory at scales where direct classical computation becomes impractical. For the largest problems studied, the paper reported that matching the D-Wave quantum processor’s simulation quality with matrix product state methods would require nearly a million years on the Frontier supercomputer, with memory and energy requirements exceeding practical limits. “D-Wave’s demonstration of beyond-classical computation continues to hold up under careful scientific scrutiny,” said Dr. Alan Baratz, CEO of D-Wave. “We welcome advances in classical methods, including recent work from the Flatiron Institute, but claims that these advances overturn D-Wave’s result are inaccurate. A claim that strong requires reproducing the full scope of our demonstration, including the hardest cases and the full set of measurements. That has not happened.” The Flatiron Institute’s BP-TNS algorithm is a meaningful contribution to the classical state of the art, and it is effective in some regimes. But it is not effective across the full range of problem classes studied in D-Wave’s Science paper. In a March 2025 response, D-Wave researchers and collaborators noted that the Tindall et al. work did not attempt the most complex lattice geometry, did not reproduce the largest simulations in 3D lattices, did not simulate the low-precision ensembles in which correlations grow fastest, and did not produce the full-state and fourth-order observables reported in D-Wave’s Science paper. In the arXiv paper “Evaluating Classical Simulations with a Quantum Processor," D-Wave researchers and collaborators further evaluated the limits of classical tensor-network simulations using a quantum processor as a reference. That work showed that BP-TNS fails for strongly coupled three-dimensional spin glasses on cubic and diamond lattices, and that loop-corrected BP-TNS is ineffective for higher-dimensional biclique problems. These are important quantum simulation regimes included in D-Wave’s original demonstration, not peripheral examples. “The BP-TNS algorithm is effective in some regimes and ineffective in others,” said Dr. Trevor Lanting, chief development officer at D-Wave. “Our analysis showed that it fails for strongly coupled three-dimensional spin glasses on cubic and diamond lattices, and that loop-corrected BP-TNS is ineffective for higher-dimensional biclique problems. These are important cases from our Science paper, and they remain beyond the reach of current classical methods.” D-Wave encourages continued work by the Flatiron Institute and others to advance classical simulation methods. Such progress is valuable and can help sharpen the boundary between classical and quantum capabilities. But scientific communication should distinguish between a meaningful advance in classical simulation and overturning a quantum supremacy result. The former is supported by the evidence. The latter is not. “We should all hold ourselves to a higher standard when communicating scientific results,” Baratz added. About D-Wave Quantum Inc.

D Wave Quantum Wins US$100 Million CHIPS Act Backing As Losses Widen
May 22, 2026
• D-Wave Quantum (NYSE:QBTS) received a $100 million equity investment from the U.S. government under the CHIPS and Science Act.
• The funding comes through the U.S. Department of Commerce as part of a broader $2 billion federal initiative in quantum computing.
• The capital is intended to support D-Wave's quantum R&D, including both annealing and gate-model platforms, and to strengthen the domestic quantum supply chain.
D-Wave Quantum enters this funding milestone with its stock at $25.74 and a very large 3-year return, along with a 35.2% return over the past year. The share price is up 16.3% over the past week and 26.4% over the past month, while year-to-date performance is down 8.5%. This gives investors a mix of shorter-term strength and earlier-year weakness to weigh against the new capital injection.
For investors watching NYSE:QBTS, the U.S. government equity stake indicates that federal agencies view D-Wave as a key participant in quantum computing efforts tied to national priorities and research leadership. The planned use of funds across R&D, scaling of hardware platforms, and supply chain development may support the development of closer government partnerships and influence how D-Wave positions itself within the broader $2 billion U.S. quantum initiative.

Quantum Breakthrough: Unhackable Keys Sent Over 120 km Using Quantum Dots
BY LIGHT PUBLISHING CENTER, CHANGCHUN INSTITUTE OF OPTICS, FINE MECHANICS AND PHYSICS, CASAPRIL 17, 2026
Single Photons Emitted by a Quantum Dot Experiment
Cover highlight of the experiment. Single photons emitted by a quantum dot embedded in a photonic device are coupled into a fiber and encoded by ‘Alice’ into three distinct time-bin qubits. After ‘Bob’ performs the decryption, a sequence of quantum keys is shared between the users. Credit: Credit: Light: Science & Applications (2026). DOI: 10.1038/s41377-026-02205-9
Quantum dot–based time-bin QKD achieves stable, long-distance secure communication with practical performance.
Quantum key distribution is the most advanced area of quantum cryptography and offers fundamentally secure communication for the future quantum internet. Solid-state light sources such as semiconductor quantum dots (SQDs) have drawn significant attention because they can generate high-quality non-classical photons for quantum communication. These sources can support higher key generation rates and may enable the use of quantum repeaters.
Another promising approach involves encoding information in the timing of photonic qubits, known as time-bin encoding, which is well-suited for long-distance communication. Time-bin qubits are especially resilient to environmental disturbances that typically disrupt optical fiber networks.
In research published in Light: Science & Applications, an international team from German and Chinese institutions reports the first true demonstration of time-bin quantum key distribution using an on-demand telecom semiconductor quantum dot device.
Experimental Time Bin Quantum Key Distribution Setup
Experimental time-bin quantum key distribution setup. A laser pulse is used to excite a quantum dot loaded in a cryostat cooled to 4K. The emitted single photons are extracted, filtered, and sent to the encoder, where three time-bin states are randomly encoded onto them. The time-bin qubits are decrypted at the receiver setup from Bob, which consists of a decoder, superconducting nanowire single-photon detector (SNSPD), and a time-to-digital converter (TDC). FPC: fiber polarization controller; PPS: programmable power source. Credit: Light: Science & Applications (2026). DOI: 10.1038/s41377-026-02205-9
High-Speed Quantum Dot System Achieves Record Key Rates Over 120 km
The researchers generated three distinct time-bin qubit states both deterministically and randomly using a self-stabilized encoder that converts polarized single photons from a telecom C-band quantum dot. At the receiving end, the qubits are decoded with an actively stabilized interferometer that includes a phase shifter, allowing continuous operation without manual adjustments. The system successfully transmitted signals over distances greater than 120 km (about 75 miles) through optical fiber while maintaining stable performance for more than 6 hours.
This proof of concept achieved the highest secure key rate reported for time-bin QKD systems using a high-performance quantum dot source. The device produces bright, high-purity single photons at an operating rate of about 76 MHz. Even after transmission across 120 km (about 75 miles) of standard optical fiber, the system keeps the average quantum bit error rate below 11%. Under realistic finite key conditions, it delivers an average secure key rate of approximately 15 bits per second, which is sufficient for practical uses such as encrypting text messages.
Stability, Performance, and Real-World Quantum Communication Impact
The researchers emphasize the significance of these results: “Telecom-band QDs with Purcell enhancement can provide high-brightness photons suitable for intercity fiber communication, making them promising candidates for integration into practical QKD systems.”
“Most existing QD-based QKD systems are vulnerable to changes in the practical quantum channel caused by environmental factors, such as turbulence, temperature, and vibrations. This necessitates active compensation. In contrast, time-bin encoding, where qubits are encoded in the temporal position of single photons, offers intrinsic stability against such channel fluctuations even without any complex compensation protocols.”
Quantum Bit Error Rate and Achievable Key Rates Over Fibre Distance
Achieved secure key rates over distance. Quantum-bit error rate and achievable key rates over fibre distance. The results show a maximum achievable transmission distance of 127km. Credit: Light: Science & Applications (2026). DOI: 10.1038/s41377-026-02205-9
They continue, “The system is operated continuously for 6 hours, highlighting the intrinsic robustness of the time-bin scheme enabled by the system, including the Sagnac interferometer (SNI), active feedback control, etc.”
“This result underscores the feasibility of integrating QD single-photon sources into stable and field-deployable time-bin QKD systems, marking an important step toward scalable, quantum-secure communication networks based on solid-state single-photon emitters.”

Quantum Computing Stocks Rally After Nvidia Unveils New AI Model SuiteApril 15, 2026 8:37 AM
IH Market News
Shares of quantum computing firms moved higher in premarket trading on Wednesday after Nvidia (NASDAQ:NVDA) introduced a new family of open-source AI models aimed at advancing development in the quantum computing space.D-Wave Quantum (NYSE:QBTS) surged more than 8% in early trading, while IonQ (NASDAQ:IONQ) climbed 6.2%. Other players in the sector, including Infleqtion (NYSE:INFQ), Rigetti Computing (NASDAQ:RGTI) and Quantum Computing (NASDAQ:QUBT), also posted gains ranging from 3.9% to 5.5%.The newly introduced platform, branded NVIDIA Ising—named after a mathematical framework used to model complex systems—is designed to support researchers and businesses in building quantum processors capable of handling real-world use cases.According to Nvidia, the models are focused on tackling two of the biggest challenges facing the industry: error correction and processor calibration. The company said the system can deliver up to 2.5 times faster performance and triple the accuracy in the decoding processes required for quantum error correction.“AI is essential to making quantum computing practical,” said Jensen Huang, founder and CEO of NVIDIA. “With Ising, AI becomes the control plane — the operating system of quantum machines — transforming fragile qubits to scalable and reliable quantum-GPU systems.”Nvidia cited estimates from Resonance projecting the global quantum computing market will surpass $11 billion by 2030, with future expansion heavily dependent on advances in scalability and error correction technologies.Quantum computing is widely seen as having the potential to address highly complex problems across fields such as physics, chemistry and cybersecurity—tasks that remain beyond the capabilities of traditional computing systems. However, the development of stable and reliable machines continues to be a major hurdle, as existing systems remain highly susceptible to errors.Nvidia stock priceD-Wave Quantum stock priceIonQ stock priceInfleqtion stock priceRigetti Computing stock priceQuantum Computing stock price

Quantum Threats Are Real. These Companies Are Building the FixMarch 6, 2026 11:00 AM
PR Newswire (US)
Issued on behalf of Quantum Secure Encryption Corp. (QSE)USA News Group News CommentaryVANCOUVER, BC, March 6, 2026 /PRNewswire/ -- A quantum-enabled cyberattack on a single major U.S. bank could trigger between $2.0 trillion and $3.3 trillion in cascading economic damage, according to a recent report from the Citi Institute[1]. That vulnerability is accelerating a global security overhaul, with global information security spending projected to reach $244.2 billion in 2026 as post-quantum cryptography emerges among the top forces reshaping enterprise defense[2]. Companies at the forefront of this transition include QSE Corp. (CSE: QSE) (OTCQB: QSEGF) (FSE: VN8), Arqit Quantum (NASDAQ: ARQQ), IonQ (NYSE: IONQ), Quantum Computing (NASDAQ: QUBT), and D-Wave Quantum (NYSE: QBTS). IDC predicts that 40% of G2000 organizations will engage cybersecurity firms to conduct quantum risk assessments by 2027, driven by looming NIST deprecation deadlines for RSA and ECC encryption[3]. Already, 97% of enterprises plan to allocate cybersecurity budget to post-quantum cryptography over the next 24 months, reflecting urgency that extends well beyond research labs[4].QSE Corp. (CSE: QSE) (OTCQB: QSEGF) (FSE: VN8) is building the security layer that enterprises and governments will need when quantum computers render today's encryption obsolete. The Vancouver-based company specializes in post-quantum cryptography, delivering a modular platform built on proprietary quantum-delivered entropy and zero-knowledge architecture designed to protect sensitive data from both current cyber threats and future quantum-enabled attacks.The platform covers multiple layers of the post-quantum security stack. QSE's Quantum Preparedness Assessment (QPA) gives organizations a structured migration methodology for identifying cryptographic exposure and planning remediation at the executive level. QAuth delivers entropy-enabled single sign-on that embeds quantum-resistant key generation directly into identity workflows. The qREK SDK lets developers integrate quantum-resilient encryption into any application, while QSE-Chat offers fully quantum-secure messaging for enterprise and government clients on both iOS and Android."Our objective is to give enterprises clarity," said Ted Carefoot, CEO of QSE. "Post-quantum transition requires structured planning. Our methodology provides measurable indicators and visibility to help organizations understand where they stand and how to prioritize next steps."That clarity is translating into commercial traction across four continents. QSE recently renewed its enterprise agreement with The Muthoot Group, one of India's largest financial services organizations, covering approximately 14,000 user licenses. The company also entered South America with a three-year security deal supporting three Brazilian government end-clients for approximately 4,500 user licenses. International distribution extends through a partnership with NUSA Networks and Porta Nusa in Indonesia and a distributor agreement with Enzo Plus spanning 300 channel partners in Southeast Asia.On the defence front, QSE joined the Canadian Association of Defence and Security Industries (CADSI) and participated at the World Defense Show 2026 in Saudi Arabia as part of the official Canadian Delegation. The company holds a CyberSecure Canada Level 2 Certification and recently joined the Municipal Information Systems Association (MISA) as a National Partner, positioning across municipal, federal, and allied defence channels as post-quantum migration timelines compress worldwide.CONTINUED...
