Pre-management of Non-local Decoherence    [PDF]

Xiao-Feng Qian

The possibility of pre-managing a non-local decoherence process with limited resources based on initial conditions is an open question. A generic two-qubit system that undergoes local but different amplitude-damping dissipations is studied to analyze the relation between entanglement sudden death (ESD) properties and initial conditions. ESD-free, ESD-tolerable and ESD-no-go phases are shown to be pre-manageable through the initial entanglement and excitation probabilities. Our results may provide useful guidance to state preparations in practice.
