论文摘要
从理论上讲，我们在存在粒子损失和脱落的情况下研究光子莫特绝缘子中的纠缠动力学。我们探索了两种配置，在将光子链链的中心位点注入或提取光子后，产生了纠缠。我们研究了两端降低密度矩阵的纠缠负态，这是时间和位点间距离的函数。我们的发现表明，尽管存在粒子损失，但量子纠缠传播表现出弹道特征，其传播速度与与动力学相关的不同的准粒子有关，分别是光子双元和整体。我们的分析表明，在两种构型中，光子耗散具有明显的不对称行为，其在Holon纠缠传播中的作用要比对Doublon案例更为引人注目。
We theoretically investigate the entanglement dynamics in photonic Mott insulators in the presence of particle losses and dephasing. We explore two configurations where entanglement is generated following the injection or extraction of a photon in the central site of a chain of cavity resonators. We study the entanglement negativity of two-site reduced density matrices as a function of time and inter-site distance. Our findings show that in spite of particle losses the quantum entanglement propagation exhibits a ballistic character with propagation speeds related to the differerent quasiparticles that are involved in the dynamics, namely photonic doublons and holons respectively. Our analysis reveals that photon dissipation has a strikingly asymmetric behavior in the two configurations with a much more dramatic role on the holon entanglement propagation than for the doublon case.
