基于伪随机相位序列调制的单光子场的量子纠缠的有效模拟

Effective Simulation of Quantum Entanglement Based on A Single-photon Field Modulated with Pseudorandom Phase Sequences

Jian Fu, Yi Hu, Shuo Sun

摘要:

我们证明了一个单光子场被n个不同的伪随机相位序列(PPS)调制,可以构成一个2^n维的希尔伯特空间,该空间具有张量积结构。利用PPS调制的单光子场,讨论了Bell态和GHZ态的有效模拟,并用相关分析和冯诺伊曼熵对模拟结果进行了表征。我们得到了与量子力学中类似的结果,并发现这些结论可以很容易地推广到n个量子粒子。对量子纠缠的模拟研究具有重要的意义,因为它不仅可以为我们提供对量子纠缠基本特性的有用认识,而且可以为量子计算提供新的见解。

英文摘要:

We demonstrate that a single-photon field modulated with n different pseudorandom phase sequences (PPSs) can constitute a 2^n-dimensional Hilbert space that contains tensor product structure. By using the single photon field modulated with PPSs, we discuss effective simulation of Bell states and GHZ state, and apply both correlation analysis and von Neumann entropy to characterize the simulation. We obtain similar results with the cases in quantum mechanics and find that the conclusions can be easily generalized to n quantum particles. The research on simulation of quantum entanglement may be important, for it not only provides useful insights into fundamental features of quantum entanglement, but also yields new insights into quantum computation.
