论文摘要
随着最近在光子学中对光子学中的量子优势示范的说法，以任意区分性的任意量子状态计算以任意量子状态的玻色子抽样计算的问题已经脱颖而出。在这项工作中，我们介绍了基于克利福德和克利福德的结果的结果。特别是，我们表明： 1）如何计算任意量子状态的边际检测概率（即检测某些但不是全部光子的概率）。 2）使用第一个结果，如何将Clifford和Clifford的采样算法推广到任意光子区分和任意输入量子状态。 3）如何将量子干扰的截断掺入采样算法中。 4）考虑了最近的光子量子优势实验的最大似然验证。
With the recent claim of a quantum advantage demonstration in photonics by Zhong et al, the question of the computation of lower-order approximations of boson sampling with arbitrary quantum states at arbitrary distinguishability has come to the fore. In this work, we present results in this direction, building on the results of Clifford and Clifford. In particular, we show: 1) How to compute marginal detection probabilities (i.e. probabilities of the detection of some but not all photons) for arbitrary quantum states. 2) Using the first result, how to generalize the sampling algorithm of Clifford and Clifford to arbitrary photon distinguishabilities and arbitrary input quantum states. 3) How to incorporate truncations of the quantum interference into a sampling algorithm. 4) A remark considering maximum likelihood verification of the recent photonic quantum advantage experiment.
