Dynamics of spatially indistinguishable particles and entanglement protection
arXiv:2008.07471 · doi:10.1103/PhysRevA.102.062429
Abstract
We provide a general framework which allows one to obtain the dynamics of 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.
