论文摘要
自我测试和半设备独立协议正在成为量子技术的首选选择，能够通过几乎没有假设和简单的实验实现来证明其量子性质。特别是对于量子随机数发生器实时监视源的可能性仅通过测量输入/输出统计来是其他经典系统无法提供的特征。这种新可能性的成本不一定会提高复杂性和降低的性能。实际上，在这里我们表明，通过由市售组件组成的简单光学设置，可以实现高生成率。我们设法证明145.5〜MHz的量子随机生成率。
Self-testing and Semi-Device Independent protocols are becoming the preferred choice for quantum technologies, being able to certify their quantum nature with few assumptions and simple experimental implementations. In particular for Quantum Random Number Generators the possibility of monitoring in real time the entropy of the source only by measuring the input/output statistics is a characteristic that no other classical system could provide. The cost of this new possibility is not necessarily increased complexity and reduced performance. Indeed, here we show that with a simple optical setup consisting of commercially available components, a high bit generation rate can be achieved. We manage to certify 145.5~MHz of quantum random bit generation rate.
