论文摘要
从理论上讲，我们研究了通过周期性的bragg间距超导码头传输的光子$ g^{（2）}（t）$，耦合到波导。我们证明，光子束和防孔持续的时间比单个量子的辐射和非辐射寿命更长。由于Borrmann效应，光子光子相关性变得不受非辐射耗散的影响，这是Bragg制度固有的轻质耦合的强烈非马克维亚集体特征。量子相关性的这种持久性为增强波导量子电动力学设置的性能开辟了新的途径。
We study theoretically the second-order correlation function $g^{(2)}(t)$ for photons transmitted through a periodic Bragg-spaced array of superconducting qubits, coupled to a waveguide. We demonstrate that photon bunching and anti-bunching persist much longer than both radiative and non-radiative lifetimes of a single qubit. The photon-photon correlations become immune to non-radiative dissipation due to the Borrmann effect, that is a strongly non-Markovian collective feature of light-qubit coupling inherent to the Bragg regime. This persistence of quantum correlations opens new avenues for enhancing the performance of setups of waveguide quantum electrodynamics.
