量子随机数发生器（QRNG）从量子力学的内在概率性质产生真正的随机性。大多数QRNG的核心问题是估计真正随机性的熵，并以高速率产生这种随机性。在这里，我们提出并演示了一个概念验证QRNG，它以24 Mbit/s的高速率通过一个高维纠缠系统，在该系统中，用户通过观察非局域量子干涉来监视真实的时间熵，而不需要详细描述设备。我们的工作提供了一个重要的方法，一个强大的QRNG与可信的，但容易出错的设备。
A quantum random number generator (QRNG) generates genuine randomness from the intrinsic probabilistic nature of quantum mechanics. The central problems for most QRNGs are estimating the entropy of the genuine randomness and producing such randomness at high rates. Here we propose and demonstrate a proof-of-concept QRNG that operates at a high rate of 24 Mbit/s by means of a high-dimensional entanglement system, in which the user monitors the entropy in real time via the observation of a nonlocal quantum interference, without a detailed characterization of the devices. Our work provides an important approach to a robust QRNG with trusted but error-prone devices.
