标题： Investigating a Device Independence Quantum Random Number Generation

摘要： 量子随机数生成（QRNG）是密码学领域不可或缺的资源。然而，对其认证一直是个挑战。本文中，我们在独立设备设置下借助量子纠缠来认证随机性，其中我们选择双光子干涉来进行源表征。CHSH 不等式违背和量子态断层扫描被用作测量设备的独立检查。这些措施确保了量子随机数生成的不可预测性。这项工作可以轻松扩展到更快的随机性扩展协议。 显示英文摘要

摘要： Quantum random number generation (QRNG) is a resource that is a necessity in the field of cryptography. However, its certification has been challenging. In this article, we certify randomness with the aid of quantum entanglement in a device independent setting, where we choose two-photon interference for source characterisation. The CHSH inequality violation and quantum state tomography are used as independent checks on the measurement devices. These measures ensure the unpredictability of quantum random number generation. This work can be easily extended to faster randomness expansion protocols.
