Research of quantum coherent dynamic uncertainty relations based on three channels
In order to investigate the effects of depolarisation channel,bit phase-flip channel and phase-damped channel three channels on the quantum coherence,firstly,analytic expressions for the l1 norm coherent sum of the initial state and the output state through these channels are derived based on two sets of canonical orthogonal bases.Furthermore,the dynamic change of the quantum coherent sum under different channels is studied.It is shown that during the process of quantum information transmission,the coherence and performance of quantum can be improved by optimizing the channel environment.The results can provide valuable references for research in quantum information processing and quantum communication.
