WiMi Develops FPGA-Based Homogeneous and Heterogeneous Digital Quantum Coprocessors
BEIJING, Jan. 7, 2025 /PRNewswire/ -- WiMi Hologram Cloud Inc. (NASDAQ: WiMi) ("WiMi" or the "Company"), a leading global Hologram Augmented Reality ("AR") Technology provider, today announced that the development team, by leveraging the flexibility and programmability of FPGAs, has proposed an innovative solution: an FPGA-based digital quantum coprocessor. This solution aims to overcome the limitations of existing quantum hardware and advance the development of quantum computing technology.
WiMi's FPGA-based Digital Quantum Coprocessor Technology is based on both homogeneous and heterogeneous structures of FPGAs. Homogeneous and heterogeneous are two key terms used to describe coprocessor architectures. A homogeneous coprocessor refers to a system where all quantum bits (qubits) are processed and computed in the same way, while a heterogeneous coprocessor allows different types of qubits or processing units to work together in different ways. Traditional quantum accelerators are typically based on physical implementations like superconducting qubits or ion traps. Although these technologies have made progress in the field of quantum computing, they face challenges related to scalability and stability. In contrast, WiMi's digital quantum coprocessor uses the digital logic of FPGAs to simulate the behavior of qubits, offering a new approach aimed at improving system stability and scalability.
WiMi's FPGA-based digital quantum coprocessor architecture is the core for implementing quantum computing functions. This architecture leverages the programmable features of FPGAs to simulate the behavior of qubits, including superposition states and quantum entanglement. The architecture needs to be carefully designed to ensure that quantum algorithms can run efficiently in a digital environment.
In a homogeneous architecture, each qubit follows the same design specifications and operational procedures. This means that all qubits use the same hardware resources and software logic. This design simplifies the complexity of the system, making it easier to manage and scale the qubits. Homogeneous architectures typically use a unified set of quantum gates, such as the Hadamard gate and CNOT gate, to implement quantum algorithms.
In contrast to the homogeneous architecture, a heterogeneous architecture allows different types of qubits or processing units to coexist, in order to accommodate various computational needs. This may include using different sets of quantum gates, quantum error correction codes, or optimizations for quantum algorithms. The design of a heterogeneous architecture is more flexible but also introduces higher complexity in terms of design and debugging.
In WiMi's FPGA-based digital quantum coprocessor technology, the IP core generator is a key tool for designing digital quantum coprocessors. It allows developers to create reusable, modular quantum computing elements that can be integrated into FPGAs. The development of the IP core generator involves a deep understanding of quantum algorithms and the efficient utilization of FPGA resources. VHDL is used to write the logical descriptions of qubits and quantum gates. Through VHDL, developers can precisely control the hardware behavior of the FPGA, enabling the implementation of complex quantum computing tasks.
The execution flow of a quantum program includes the encoding of quantum algorithms, the initialization of qubits, the operation of quantum gates, and the final measurement and output of results. Implementing this process on an FPGA requires precise timing synchronization and resource management. The simulation of digital quantum bits involves the digital representation of quantum superposition states and quantum entanglement. This requires the use of probabilistic models to handle the results of quantum measurements and to implement the randomness inherent in quantum algorithms.
WiMi's FPGA-based digital quantum coprocessor technology digitizes qubits by converting their states and behaviors into digital signals and logical operations. This is similar to the pipelined design of RISC (Reduced Instruction Set Computing) processors, both emphasizing parallel processing and resource optimization.
The FPGA-based digital quantum coprocessor architecture provides a new approach to implementing quantum computing functions. By carefully designing both homogeneous and heterogeneous architectures, and utilizing tools such as the IP core generator and VHDL, it is possible to achieve efficient and stable quantum computing solutions.
WiMi's homogeneous and heterogeneous digital quantum coprocessors represent an innovative technology that brings new vitality to the field of quantum computing. By leveraging the flexibility and programmability of FPGAs, this technology not only enhances the stability and scalability of quantum computing but also provides a new approach for implementing quantum algorithms. The design of homogeneous and heterogeneous architectures each has its advantages, offering customized solutions for different application scenarios. While challenges remain, these challenges also present new opportunities for the development of quantum computing technology.
The development of this technology by WiMi will not only drive advancements in scientific research but also have a profound impact on society and the economy. The commercialization of quantum computing applications will bring revolutionary changes across various industries, improving productivity and solving problems that traditional computers struggle with. WiMi will continue to explore and innovate in the field of quantum computing, constantly optimizing and refining FPGA-based digital quantum coprocessor technology. As the technology matures and its applications expand, quantum computing is expected to usher in a new era of computing, making a significant contribution to the development of human society.

WiMi Develops a Quantum Technology-Based Random Access Memory Architecture
BEIJING, Dec. 26, 2024 /PRNewswire/ -- WiMi Hologram Cloud Inc. (NASDAQ: WiMi) ("WiMi" or the "Company"), a leading global Hologram Augmented Reality ("AR") Technology provider, today announced the development of a Quantum Technology-Based Random Access Memory Architecture, known as QRAM. This architecture successfully implements fundamental logical operations such as AND, OR, NOT, and NOR gates in quantum logic gates by combining key basic operations in quantum computing, such as the CNOT gate, V gate, and V+ gate. Quantum Random Access Memory (QRAM) is a memory architecture specifically designed for quantum computing environments, with the core goal of enabling efficient reading and writing of information while maintaining the state of the quantum system. The design of QRAM is not only intended to leverage the parallel processing capabilities of quantum computing but also to utilize quantum properties such as superposition and entanglement to significantly enhance computational efficiency.
In WiMi's QRAM architecture, the quantum CNOT gate, V gate, and V+ gate serve as the fundamental operation units. Each quantum operation is equivalent to certain logical operations in classical computing, but simultaneously leverages the properties of quantum states to achieve efficient computation.
CNOT Gate (Controlled-NOT Gate): The CNOT gate is a crucial operation in quantum computing, used to control the relationship between two quantum bits (qubits). In classical computing, this is similar to the function of an XOR gate, but in the quantum environment, it allows qubits to exist in a superposition of states, enabling the simultaneous processing of multiple states.
V Gate and V+ Gate: The V gate and V+ gate are quantum gates used to implement more complex logic. The operations of these two gates are similar to the AND and OR gates in classical computing. However, their advantage lies in the ability to process multiple potential outcomes in the quantum system simultaneously, without the need to evaluate each possibility separately.
By combining these fundamental quantum gates, basic operations in quantum logic such as AND, OR, NOT, and NOR can be successfully implemented. This provides the necessary support for designing complex quantum circuits, while being more flexible and efficient compared to classical logic gates.
One of the major advantages of the QRAM architecture is its full utilization of the properties of quantum superposition and quantum entanglement. In classical computing, memory read and write operations are linear and must be performed sequentially. However, in quantum computing, because qubits can exist in multiple states (superposition), parallel read and write operations can be performed simultaneously. This ability significantly enhances computational efficiency, especially when handling large-scale datasets or complex computational tasks.
Additionally, quantum entanglement enables the correlation between multiple qubits without the need for direct communication, further improving the speed of data transfer and computation. Memory operations with entangled qubits are much faster and more efficient than traditional memory operations, opening up new possibilities for parallel computing.
In WiMi's QRAM architecture, the entire design logic includes several key steps and technical nodes, such as quantum state-based random access, the introduction of quantum error correction mechanisms, and seamless integration with quantum computers.
The core feature of QRAM is its ability to perform random access within a quantum system. Traditional computer RAM achieves reading and writing to memory units through address buses, data buses, and other components, whereas QRAM accomplishes this process through the states of quantum bits (qubits). By utilizing quantum superposition, multiple addresses can be accessed simultaneously in a single operation. This means that in a QRAM system, data can be accessed in parallel across multiple addresses, greatly improving the efficiency of data operations.
To achieve this, WiMi has designed a system based on CNOT gates, V gates, and V+ gates. These quantum gates allow flexible control over memory access processes while maintaining the quantum state of the system and ensuring the efficient transmission of qubits in an entangled state. Through this system, QRAM not only enables high-speed data reading and writing, but also ensures the reliability and accuracy of information processing.
Furthermore, error correction is crucial in any quantum computing system. Due to the fragile nature of qubit states, even small external disturbances can cause computational errors. Therefore, WiMi's QRAM architecture incorporates a quantum error correction mechanism to ensure that the qubit states are accurately preserved and transmitted during data reading and writing. This includes an error correction method based on quantum entanglement, where redundant entangled qubits are introduced to detect and correct potential errors. This method not only effectively reduces the impact of external noise on the system but also ensures the stability of data during multiple read operations.
WiMi's QRAM design is intended to seamlessly integrate with quantum computers. Since quantum computing operations depend on the superposition and entanglement states of qubits, the QRAM system demonstrates high compatibility when interfacing with a quantum processing unit (QPU). The design ensures smooth transmission of qubits between memory and processor during data access, thereby significantly improving computational efficiency.
By utilizing the V gate, V+ gate, and CNOT gate, WiMi's QRAM system can quickly execute quantum logic operations and, when handling complex computational tasks, can read and write data at near-real-time speeds. This makes QRAM a key component in large-scale quantum computing applications.
The successful development of QRAM technology has had a revolutionary impact across multiple fields. As a critical component of quantum computers, QRAM will significantly enhance the overall performance of quantum computing systems. Its efficient parallel data access capabilities make it especially well-suited for handling large-scale computational tasks such as molecular simulations, climate modeling, and complex optimization problems. By significantly reducing computation time, QRAM will play an indispensable role in the future of high-performance quantum computing.
Another important application of QRAM is in quantum communication and quantum encryption. By leveraging quantum entanglement, QRAM can enable high-speed data transmission while ensuring data security. The non-locality of quantum entanglement guarantees that data cannot be intercepted during transmission, providing a solid foundation for future quantum encryption technologies.
With the development of quantum computing, the field of quantum machine learning has also gradually emerged. QRAM's efficient data access capabilities make it highly suitable for handling large-scale datasets, enabling model training to be completed in a shorter time. This will significantly advance the development of quantum artificial intelligence, allowing complex machine learning tasks to be solved quickly on quantum computers.
As quantum technology continues to evolve, QRAM, as a core technology, will provide crucial support for the future of quantum computing. WiMi is committed to continuing the development of QRAM technology, continually optimizing its performance, reducing implementation costs, and expanding its applications across various industries.
The successful development of QRAM technology marks an important step in the advancement of quantum computing. As quantum computers progress and quantum technologies mature, QRAM will become an indispensable core component of quantum computing systems. With the ongoing optimization and promotion of this technology, QRAM is expected to bring disruptive innovations across multiple fields and lay a solid foundation for the arrival of the quantum era.
