论文摘要
我们相信随机数是真正随机的能力，对于像密码学和量子力学基本测试的多样化的领域至关重要。现有的解决方案都有缺点 - 独立于设备的量子随机数发生器（QRNG）是高度不切实际的，标准的半设备独立QRNG仅限于特定的物理实现和信任水平。在这里，我们使用信号快门的形式的可信真空来源为半独立的随机性认证提供了一个新的框架。它采用了一组灵活的假设和信任水平，从而可以在涉及量子和经典熵来源的各种物理场景中应用。我们通过光子设置在实验上证明我们的协议，并在三个不同的假设下生成安全的随机位，并具有不同程度的安全性和结果数据速率。
Our ability to trust that a random number is truly random is essential for fields as diverse as cryptography and fundamental tests of quantum mechanics. Existing solutions both come with drawbacks -- device-independent quantum random number generators (QRNGs) are highly impractical and standard semi-device-independent QRNGs are limited to a specific physical implementation and level of trust. Here we propose a new framework for semi-device-independent randomness certification, using a source of trusted vacuum in the form of a signal shutter. It employs a flexible set of assumptions and levels of trust, allowing it to be applied in a wide range of physical scenarios involving both quantum and classical entropy sources. We experimentally demonstrate our protocol with a photonic setup and generate secure random bits under three different assumptions with varying degrees of security and resulting data rates.
