Motion-Enhanced Quantum Entanglement in the Dynamics of Excitation Transfer

【摘要】 We investigate the dynamics of entanglement in the excitation transfer through a model consisting of three interacting molecules coupled to environments.It is shown that the entanglement can be further enhanced if the distance between the molecules is oscillating.Our results demonstrate that the motional effect plays a constructive role on quantum entanglement in the dynamics of excitation transfer.This mechanism might provide a useful guideline for designing artificial systems to battle against decoherence.更多还原
