SHENZHEN, China, Jan. 14,
2025 /PRNewswire/ -- MicroCloud Hologram Inc.
(NASDAQ: HOLO), ("HOLO" or the "Company"), today announced the
development and application of Quantum Nonlinear Optical Holography
(QNOH) technology to directly generate spatially entangled qudits.
This technology leverages the Spontaneous Parametric
Down-Conversion (SPDC) process in quantum optics, precisely shaping
the spatial quantum correlations of entangled photon pairs within a
two-dimensional patterned nonlinear photonic crystal, without the
need for complex pump shaping. This innovation not only breaks
through the limitations of traditional optics but also offers
unprecedented application prospects for quantum key distribution
(QKD) and quantum computing based on spatial degrees of
freedom.
Quantum Nonlinear Optical Holography technology combines the
advantages of quantum optics, nonlinear optics, and holography,
aiming to directly shape the spatial properties of quantum photons
through nonlinear optical processes. Traditional nonlinear optical
holography has been widely applied in the field of classical
optics, particularly in areas such as information storage, beam
control, and optical communication. However, its application in the
quantum domain has been relatively scarce, as shaping quantum
states typically requires higher precision and more complex
interventions.
The key innovation of Quantum Nonlinear Optical Holography
technology is its ability to directly generate spatially entangled
qudits through the Spontaneous Parametric Down-Conversion process,
overcoming the limitations of conventional quantum optical
techniques. A qudit is a high-dimensional quantum system, which,
compared to the traditional qubit, has more degrees of freedom and
can store more information. Therefore, it holds greater promise for
applications in quantum computing and quantum communication.
The core implementation of HOLO's Quantum Nonlinear Optical
Holography technology relies on the Spontaneous Parametric
Down-Conversion process. In this process, a single high-energy
photon enters a nonlinear optical medium (such as a BBO crystal)
and, through interaction with the crystal, splits into two
lower-energy photons, which are referred to as the signal photon
and the idler photon. These two photons exhibit quantum
entanglement, meaning their states are tightly correlated,
regardless of the spatial distance between them.
Unlike traditional quantum optical technologies, this technique
uses a two-dimensional patterned nonlinear photonic crystal. In
such a crystal, photons can be precisely controlled in predefined
spatial degrees of freedom. By manipulating the patterned structure
of the crystal, the spatial quantum correlations of the entangled
photon pairs can be directionally shaped, thereby generating the
desired quantum states.
What sets HOLO's Quantum Nonlinear Optical Holography technology
apart is that it does not require complex pump light shaping.
Traditional quantum optical systems typically rely on specific
shapes and frequency adjustments of the pump light source to ensure
that the generated quantum states meet the desired criteria.
However, QNOH technology achieves direct manipulation of the
spatial properties of entangled photon pairs by controlling the
structure and material properties of the nonlinear photonic
crystal, making the process more efficient and stable.
In traditional quantum information processing, the quantum bit
(qubit) is widely used as the basic unit. However, the
computational and storage capacity of a qubit is limited by its
binary states (0 or 1). In contrast, a qudit (a high-dimensional
quantum system) can process information in higher dimensions,
offering greater potential for quantum computing and quantum
communication.
One of the biggest breakthroughs of HOLO technology is its
ability to generate spatially entangled qudits. By precisely
controlling the design of the photonic crystal, the technical team
successfully endowed photon pairs with multiple degrees of freedom
within a two-dimensional space, allowing each entangled photon pair
to move beyond traditional binary states and expand into higher
dimensions. These quantum states can manifest as different quantum
modes and frequencies, significantly enhancing the capacity and
diversity of the quantum system.
HOLO's Quantum Nonlinear Optical Holography technology generates
spatially entangled qudits through the following steps:
Photon Source Selection and Control: Through the precisely
designed nonlinear photonic crystal, an appropriate pump light
source is chosen to excite the signal and idler photons in the
Spontaneous Parametric Down-Conversion process. These photon pairs
are highly entangled and can be precisely controlled in spatial
degrees of freedom.
2D Patterned Crystal Design: A two-dimensional patterned
nonlinear photonic crystal is used to control the propagation paths
and interactions of photons within the crystal, allowing the
spatial quantum correlations of the signal and idler photon pairs
to be shaped according to design requirements. This structure not
only enhances the stability of quantum entanglement but also
enables information encoding and decoding across different
dimensions.
Shaping Spatial Quantum Correlations: By adjusting the phase and
amplitude at different positions within the photonic crystal, the
spatial correlations of the generated entangled photon pairs are
ensured to match the desired quantum state. This allows the quantum
information of the photons to be transmitted in a more efficient
and multidimensional manner.
Quantum State Verification: Experimental verification shows that
the quantum states generated by this technology not only possess
spatial quantum correlations but also violate the
Clauser-Horne-Shimony-Holt (CHSH) inequality, proving their
entangled nature. According to the fundamental principles of
quantum mechanics, the violation of this inequality indicates the
authenticity of quantum information and the validity of quantum
entanglement.
The successful development of HOLO's QNOH technology has brought
a significant breakthrough to the fields of quantum key
distribution (QKD) and quantum communication. Entanglement-based
quantum key distribution is one of the core technologies in quantum
communication today, ensuring the security of key exchange through
the properties of quantum entanglement. The high-dimensional
entangled qudits generated by the QNOH technology can provide
higher key transmission rates and stronger resistance to
interference, thereby enhancing the security and efficiency of
quantum communication networks.
Additionally, HOLO's QNOH technology is also noteworthy for its
application in quantum computing. Since quantum computing can
process information in high-dimensional quantum states, the
generation of qudits will greatly improve the parallelism and
efficiency of quantum computing. Traditional quantum computing uses
quantum bits for computation, while high-dimensional qudits can
store more information and perform more complex computational
tasks, thereby accelerating the execution of quantum
algorithms.
HOLO's Quantum Nonlinear Optical Holography technology not only
brings new possibilities to quantum communication and quantum
computing but also paves the way for the future development of
quantum information science. In the future, as this technology
continues to improve, it may find broader applications in fields
such as quantum networks, quantum encryption, and quantum
simulation.
In future research, optimizing the design of two-dimensional
photonic crystals to further enhance the efficiency and stability
of spatially entangled qudit generation will become a key issue in
the field of quantum optics. Meanwhile, Quantum Nonlinear Optical
Holography technology is also expected to integrate with other
quantum technologies, such as quantum sensing and quantum imaging,
opening up more application scenarios in the field of quantum
science.
The successful development of Quantum Nonlinear Optical
Holography technology marks a significant advancement in the field
of quantum optics. By precisely generating spatially entangled
qudits, this technology offers a fresh perspective and more
powerful tools for various fields, including quantum communication,
quantum computing, and quantum information processing. As quantum
technology continues to mature, quantum networks and quantum
computers in the future are expected to enter a new era of greater
efficiency and security, driven by this innovative technology.
