SHENZHEN, China, Jan. 22, 2025 /PRNewswire/ -- Recently, MicroCloud Hologram Inc. (NASDAQ: HOLO), ("HOLO" or the "Company"), a technology service provider, made a new research breakthrough. They have constructed a quantum random number generator (QRNG) of the properties of superposition and entanglement entirely based on quantum walks.

Quantum walks, as a process of quantum state evolution, possess unique properties of superposition and entanglement. HOLO has cleverly utilized these properties to construct the quantum random number generator (QRNG). Quantum walks offer several advantages, among which the ability to generate multiple bits from a single qubit is particularly noteworthy. In traditional random number generation methods, obtaining multiple bits from a single bit source faces many limitations, while quantum walks break through these constraints, greatly enhancing the efficiency and flexibility of random number generation.

In any practical system, the application of quantum walks has certain limitations. The practical limits are primarily determined by the number of quantum walk steps that can be achieved experimentally. For example, in experimental scenarios such as nuclear magnetic resonance, ion trapping, cold atoms, and photonic systems, the number of quantum walk steps is constrained by factors like the precision of experimental equipment and environmental noise interference. However, HOLO, through in-depth analysis and numerical simulations, has found that despite these limitations, the dynamics of quantum walks can still significantly enhance the randomness of the particle's initial state.

In their research, HOLO considers a special form of randomness quantification in quantum systems, namely the inherent randomness of measurements, which has been quantified as coherent measurement. Through the study of coherent measurements, HOLO further clarifies the operational aspects of quantum coherence. Quantum coherence is one of the key characteristics that distinguish quantum systems from classical systems, and a deeper understanding of its operational aspects helps to better utilize quantum properties for random number generation.

Since the QRNG protocol proposed by HOLO is entirely based on discrete-time quantum walk (DTQW) dynamics, it requires good randomness metrics to be incorporated in both the position and coin spaces. In the theoretical framework of quantum walks, coin space and position space are two key concepts. The coin space is analogous to the probability distribution in classical random processes, while the position space describes the particle's position state in space.

To assess the randomness associated with the coin space, HOLO employs a specific method. First, it is necessary to trace a portion of the Hilbert space related to the position space from the density matrix. The density matrix is a crucial tool in quantum mechanics for describing the state of a quantum system, and by manipulating it, information related to specific spaces can be extracted. After tracing out the portion related to the position space, HOLO can calculate the randomness described in the method section from the simplified density matrix. This calculation method, based on relevant theories in quantum information theory, enables accurate quantification of randomness in the coin space.

Similarly, by tracing the coin space, HOLO can calculate the randomness combined with the position space. Through separate calculations of the randomness in these two spaces and their comprehensive analysis, a thorough evaluation of the randomness quality of the quantum walk-based QRNG can be achieved. This dual consideration of randomness in both position and coin spaces makes the QRNG proposed by HOLO more comprehensive and reliable in terms of randomness generation.

Compared to traditional random number generation methods, HOLO's quantum walk-based QRNG offers significant advantages. Traditional random number generators are often limited by algorithms and hardware, and the random numbers they generate have certain limitations in terms of randomness and unpredictability. In contrast, the quantum walk-based QRNG leverages the inherent properties of quantum systems to generate truly random numbers, whose randomness is not constrained by classical algorithms, offering higher security and reliability.

In practical applications, HOLO's QRNG has broad prospects. In the field of cryptography, the security and randomness of random numbers are critical to encryption algorithms. The quantum walk-based QRNG can provide high-quality random keys for encryption algorithms, enhancing the security of cryptographic systems and effectively defending against various forms of attacks. In fields such as scientific computing and simulation, high-quality random numbers can also improve the accuracy and reliability of computational results, providing strong support for scientific research.

In the future, HOLO will continue to conduct in-depth research on quantum walk-based QRNG technology, constantly optimizing algorithms and experimental schemes, overcoming limitations in practical applications, and further improving the performance and stability of QRNGs.
