论文摘要
我们提供了一个通用框架，该框架允许人们获得$ n $非互动的动力学在空间上无法区分的粒子本地与分离的环境耦合。该方法是普遍的，对玻色子和费米子以及任何类型的系统环境相互作用都是有效的。然后将其应用于在范式的马尔可夫噪声下研究两个相同量子位的动力学，例如相阻尼，去极化和振幅阻尼。我们发现，相同Qubits的空间不可区分性是系统的可控内在特性，可保护量子纠缠免受有害噪声的影响。
We provide a general framework which allows one to obtain the dynamics of $N$ noninteracting spatially indistinguishable particles locally coupled to separated environments. The approach is universal, being valid for both bosons and fermions and for any type of system-environment interaction. It is then applied to study the dynamics of two identical qubits under paradigmatic Markovian noises, such as phase damping, depolarizing and amplitude damping. We find that spatial indistinguishability of identical qubits is a controllable intrinsic property of the system which protects quantum entanglement against detrimental noise.
