Quantum speed limits in dephasing dynamics of a qubit system coupled to thermal environments
Xiangji Cai, Yanyan Feng, Jing Ren +4
We theoretically study the quantum speed limits (QSLs) of a qubit system coupled to a thermal dephasing environment with an Ohmic-like spectral density. Based on the geometric QSLs…

Quantum decoherence dynamics in stochastically fluctuating environments
Xiangji Cai, Yanyan Feng, Jing Ren +2
We theoretically study the decoherence of a two-level quantum system coupled to noisy environments exhibiting linear and quadratic fluctuations within the framework of a stochastic…
