MicroCloud Hologram Inc. Researches an Efficient High-Dimensional Quantum Key Distribution Protocol Based on Quantum Fourier Transform for Quantum Transmission

SHENZHEN, China, March 14, 2025 /PRNewswire/ -- MicroCloud Hologram Inc. (NASDAQ: HOLO), ("HOLO" or the "Company"), a technology service provider, they announced the proposal of an efficient high-dimensional quantum key distribution protocol for quantum transmission based on quantum Fourier transform, which brings a groundbreaking direction to the field. In this innovative proposal, the core inherent coding framework constructs a secure and reliable solution for key distribution. This framework utilizes two key quantum operations: quantum Fourier transform and quantum-controlled NOT gate, to achieve the clever concealment of secret information.

Specifically, the secret information is concealed within the relative phases of the generated high-dimensional entangled states. Quantum Fourier transform, an important tool in quantum computing, can convert quantum states between different basis vectors, providing a rich dimensional space for information encoding. The quantum-controlled NOT gate precisely flips the state of a qubit, and together, these two operations allow the information to be securely stored in the form of high-dimensional entangled states. When key information needs to be decoded, after performing the reverse operation, single-particle measurements are made using two mutually unbiased bases. Mutually unbiased bases are an important concept in quantum mechanics, where no information is leaked between the two bases, ensuring that the measurement process does not disturb the quantum state's information, while still accurately extracting the key information. Through this carefully designed decoding method, the secret information initially hidden in the high-dimensional entangled state can be effectively recovered.

In the QKD protocol proposed by HOLO, the use of keys in the form of high-dimensional quantum states becomes the key factor in breaking the limits of information efficiency. Compared to traditional binary quantum states, high-dimensional quantum states have a richer information-carrying capacity. Traditional binary quantum states can only represent two states, 0 and 1, whereas high-dimensional quantum states can encode information in multiple dimensions, significantly increasing the amount of information each particle can carry and successfully breaking the previous information efficiency limit of 1 bit per particle.

In terms of security and capacity, HOLO's QKD protocol demonstrates superior cryptographic performance, surpassing traditional cryptographic protocols. Most traditional cryptographic protocols are based on mathematical problems, such as the RSA algorithm, which relies on the large integer factorization problem. As computational power continues to improve, these traditional cryptographic protocols face the risk of being compromised. In contrast, HOLO's QKD protocol is based on fundamental principles of quantum mechanics, such as the quantum no-cloning theorem and Heisenberg's uncertainty principle, which fundamentally eliminate the possibility of information eavesdropping or tampering. Regarding capacity, the high-dimensional quantum state key can carry more information, enabling the protocol to transmit more keys under the same time and resource conditions, thus meeting the growing demands for information security and efficient transmission in the era of big data.

The efficient high-dimensional quantum key distribution protocol for quantum transmission based on quantum Fourier transform, proposed by HOLO, achieves multiple breakthroughs on the technical level. From breaking the limits of information efficiency to ensuring high security, and surpassing the performance of traditional cryptographic protocols, this protocol lays a solid foundation for the future development of quantum key distribution technology. It is expected to lead the field into a new stage of development.
