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 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.

具有灵活假设的半设备无关随机数生成

我们相信随机数是真正随机的能力对于诸如密码学和量子力学的基础测试等众多领域至关重要。现有的解决方案都具有缺点-与设备无关的量子随机数生成器(QRNG)非常不切实际,而与标准的与半设备无关的QRNG限于特定的物理实现和信任级别。在这里,我们使用信号快门形式的可信真空源,提出了一个独立于半设备的随机性认证的框架。它采用了一组灵活的假设和信任级别,使其可以应用于涉及量子和经典熵源的各种物理场景。
