论文摘要
我们研究了玻色子系统的Leggett-Garg不平等现象（LGI），该系统通过变形Pegg-barnett相算子给出了可观察物。我们考虑两个可观察的物品，并表明量子傅立叶变换在实现所需测量值的实现中很有用。使用连贯的状态$ |α\ rangle $作为初始状态得出LGI的明确表格，我们探讨了当相位运算符的观察结果之间的时间差异时，它们违反了它们。我们表明，该系统在较大的幅度极限中仍然不存在，而不会耗散，但是随着耗散的影响，我们的违规行为会迅速减少。
We investigate the Leggett-Garg inequalities (LGIs) for a boson system whose observables are given by deforming the Pegg-Barnett phase operators. We consider two observables and show that the quantum Fourier transform is useful in the realization of the required measurements. Deriving explicit forms for the LGIs using the coherent state $|α\rangle$ as the initial state, we explore the regimes where they are violated when the time difference between observations of the phase operators is varied. We show that the system remains nonclassical in the large amplitude limit without dissipation, however with dissipation, our violation diminishes rapidly.
