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.

中国深圳2025年1月22日 /美通社/ -- 近日，科技服务提供商微云全息科技有限公司（纳斯达克股票代码：HOLO）（“HOLO”或“公司”）取得了新的研究突破。他们完全基于量子行走构建了具有叠加和纠缠性质的量子随机数生成器（QRNG）。

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.

量子行走作为量子态演化的过程，具有独特的叠加和纠缠性质。 HOLO巧妙地利用这些特性构建了量子随机数发生器（QRNG）。量子行走具有多种优势，其中从单个量子位生成多个位的能力尤其值得注意。在传统的随机数生成方法中，从单个比特源获取多个比特面临许多限制，而量子游走则突破了这些限制，大大增强了随机数生成的效率和灵活性。

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.

在任何实际系统中，量子行走的应用都有一定的局限性。实际限制主要由实验上可以实现的量子行走步数决定。例如，在核磁共振、离子捕获、冷原子、光子系统等实验场景中，量子行走步数受到实验设备精度、环境噪声干扰等因素的限制。然而，HOLO通过深入分析和数值模拟发现，尽管有这些限制，量子行走的动力学仍然可以显着增强粒子初始状态的随机性。

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.

HOLO 在他们的研究中考虑了量子系统中随机性量化的一种特殊形式，即测量的固有随机性，它已被量化为相干测量。通过相干测量的研究，HOLO 进一步阐明了量子相干性的操作方面。量子相干性是区分量子系统与经典系统的关键特征之一，对其操作方面的更深入理解有助于更好地利用量子特性来生成随机数。

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.

由于HOLO提出的QRNG协议完全基于离散时间量子游走（DTQW）动力学，因此它需要在位置和硬币空间中纳入良好的随机性度量。在量子行走的理论框架中，硬币空间和位置空间是两个关键概念。硬币空间类似于经典随机过程中的概率分布，而位置空间描述了粒子在空间中的位置状态。

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.

为了评估与币空间相关的随机性，HOLO 采用了一种特定的方法。首先，需要从密度矩阵中追踪出与位置空间相关的希尔伯特空间的一部分。密度矩阵是量子力学中描述量子系统状态的重要工具，通过操纵它，可以提取与特定空间相关的信息。在追踪出与位置空间相关的部分后，HOLO可以从简化的密度矩阵中计算出方法部分中描述的随机性。这种计算方法基于量子信息论的相关理论，能够准确量化硬币空间的随机性。

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.

同样，通过追踪币空间，HOLO可以结合仓位空间来计算随机性。通过分别计算这两个空间的随机性并对其进行综合分析，可以实现对基于量子游走的QRNG的随机性质量的全面评估。这种对仓位和币空间随机性的双重考虑，使得HOLO提出的QRNG在随机性生成方面更加全面可靠。

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.

与传统的随机数生成方法相比，HOLO 基于量子游走的 QRNG 具有显着的优势。传统的随机数生成器往往受到算法和硬件的限制，其生成的随机数在随机性和不可预测性方面存在一定的局限性。相比之下，基于量子行走的QRNG利用量子系统的固有特性来生成真正的随机数，其随机性不受经典算法的限制，具有更高的安全性和可靠性。

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.

在实际应用中，HOLO的QRNG具有广阔的前景。在密码学领域，随机数的安全性和随机性对于加密算法至关重要。基于量子游走的QRNG可以为加密算法提供高质量的随机密钥，增强密码系统的安全性，有效防御各种形式的攻击。在科学计算和模拟等领域，高质量的随机数还可以提高计算结果的准确性和可靠性，为科学研究提供有力的支持。

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.

未来，HOLO将继续深入研究基于量子行走的QRNG技术，不断优化算法和实验方案，克服实际应用中的局限性，进一步提高QRNG的性能和稳定性。
