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…
