Dynamics of Measurement-Induced Disturbance for a Qubit-Qutrit System in Noninertial Frames
Hao Yuan, Lian-Fu Wei · Communications in Theoretical Physics · 2013
We investigate the dynamics of measurement-induced disturbance (MID) for a qubit-qutrit system in noninertial frames under various multi-local decoherence channels (i.e., dephasing, phase-flip, bit-(trit-) flip, bit-(trit-) phase-flip, and depolarizing channels). We find that, for any acceleration, the MID can decay in a monotonic way to zero or to a nonzero steady value (i.e., residual MID exists). Consequently, no sudden death of the MID occurs, which is different from entanglement.
