耗散免疫光子-光子关联的量子Borrmann效应
Quantum Borrmann effect for dissipation-immune photon-photon correlations
摘要：
本文从理论上研究了光子通过周期性布拉格间隔超导量子比特阵列耦合到波导中的二阶关联函数$g^{(2)}(t)$。我们证明了光子聚束和反聚束的持续时间比单个量子比特的辐射和非辐射寿命长得多。由于Borrmann效应，光子-光子相关性变得不受非辐射耗散的影响，Borrmann效应是布拉格机制固有的光-量子比特耦合的强烈非马尔可夫集体特征。这种量子关联的持久性为提高波导量子电动力学装置的性能开辟了新的途径。
英文摘要：
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.
