论文摘要
我们提出了一种从不受信任的测量设备和受信任来源的量子随机数生成的方案，并通过实验证明了它。不需要关于测量中噪声或瑕疵的假设，并且该方案易于使用现有技术实施。测量装置用一些可信的状态进行探测，并且输出熵可以在观察到的结果分布上降低限制。该方案可以应用于具有任何有限的结果的测量值，尤其可以通过使用相干状态探测的探测器对真空的同源测量来实现，因为我们通过强度调节电信波长飞行员激光器的强度调节，然后通过模拟到数量的对象进行了同种动力学检测和iCtigation-nigitigital-digitial-digital-tigitial-tigital conserconion的强度调节。我们表明，随机性可以在存在高斯添加噪声和非高斯瑕疵的情况下得到认证。
We present a scheme for quantum random-number generation from an untrusted measurement device and a trusted source and demonstrate it experimentally. No assumptions about noise or imperfections in the measurement are required, and the scheme is simple to implement with existing technology. The measurement device is probed with a few trusted states and the output entropy can be lower bounded conditioned on the observed outcome distribution. The protocol can be applied to measurements with any finite number of outcomes and in particular can be realised by homodyne measurements of the vacuum using a detector probed by coherent states, as we experimentally demonstrate by intensity modulation of a telecom-wavelength pilot laser followed by homodyne detection and discretisation by analog-to-digital conversion. We show that randomness can be certified in the presence of both Gaussian additive noise and non-Gaussian imperfections.
