AI 中文摘要
我们提出并分析了一种基于三体量子系统的新型量子随机数发生器，其中两个子系统用作探测器。在量子非破坏性测量方案中，一个探测器用于验证系统演化中存在真正的量子效应，而第二个探测器则从可优化的分布中生成随机数，以最大化其熵。使用一个两能级系统和两个三能级系统，我们生成了来自近乎均匀的三结果分布的随机数，产生接近最大的熵，因此实现了接近最优的随机数生成。该协议的一个关键特征是随机数生成和认证同时发生。此外，认证不依赖于探测器之间的类空间隔，消除了设备无关方法的一个主要限制。这一特性使得该协议能够实际实现并促进设备的小型化，使其成为可扩展量子技术的有前途候选方案。
英文摘要
We propose and analyze a novel quantum random-number generator based on a tripartite quantum system in which two subsystems act as detectors. Within a quantum non-demolition measurement scheme, one detector is used to certify the presence of genuine quantum effects in the system's evolution, while the second generates random numbers from a distribution that can be optimized to maximize their entropy. Using one two-level system and two three-level systems, we generate random numbers from a nearly uniform three-outcome distribution, yielding close-to-maximal entropy and therefore near-optimal randomness generation. A key feature of the protocol is that randomness generation and certification occur simultaneously. Moreover, certification does not rely on spacelike separation between detectors, removing a major constraint of device-independent approaches. This property enables practical implementation and facilitates the miniaturization of the device, making the protocol a promising candidate for scalable quantum technologies.
