Decoherence control mechanisms of a charged magneto-oscillator in contact with different environments

摘要

In this work, we consider two different techniques based on reservoir engineering process and quantum Zeno control method to analyze the decoherence control mechanism of a charged magneto-oscillator in contact with different type of environment. Our analysis reveals that both the control mechanisms are very much sensitive on the details of different environmental spectrum (J(omega)), and also on different system and reservoir parameters, e.g., external magnetic field (r(c)), confinement length (r(0)), temperature (T), cut-off frequency of reservoir spectrum (omega(cut)), and measurement interval (tau). We also demonstrate the manipulation scheme of the continuous passage from decay suppression to decay acceleration by tuning the above mentioned or reservoir parameters,e.g., r(c), r(0), T, and tau.
