摘要

玻色子采样已经在理论上被提出,并在实验中被证明具有量子计算优势。然而,人们对玻色子采样的实际应用仍缺乏深入了解。在此,我们提出玻色子采样可用于高效模拟多个相同玻色子的功分布。我们将功分布与玻色子采样联系起来,数值计算了一维量子活塞系统中单玻色子特征态之间的过渡振幅矩阵,然后将矩阵映射到玻色子采样的线性光学网络中。利用分组概率估计方法,可以通过玻色子采样的输出概率有效地模拟功分布。该方案最多需要多项式数量的采样和光学元件。我们的工作为仅使用光子和线性光学计算复杂量子功分布开辟了一条新路。

Efficiently simulating the work distribution of multiple identical bosons with boson sampling

Efficiently simulating the work distribution of multiple identical bosons with boson sampling

Boson sampling has been theoretically proposed and experimentally demonstrated to show quantum computational advantages. However, it still lacks the deep understanding of the practical applications of boson sampling. Here we propose that boson sampling can be used to efficiently simulate the work distribution of multiple identical bosons. We link the work distribution to boson sampling and numerically calculate the transition amplitude matrix between the single-boson eigenstates in a one-dimensional quantum piston system, and then map the matrix to a linear optical network of boson sampling. The work distribution can be efficiently simulated by the output probabilities of boson sampling using the method of the grouped probability estimation. The scheme requires at most a polynomial number of the samples and the optical elements. Our work opens up a new path towards the calculation of complex quantum work distribution using only photons and linear optics.
