Non-Markovian dynamics of mixed-state geometric phase of dissipative qubits
Wei Guo, Jian Ma, Xiaolei Yin +2
We investigate the geometric phase of a two-level atom (qubit) coupled to a bosonic reservoir with Lorentzian spectral density, and find that for the non-Markovian dynamics in whic…

Spin Squeezing under Non-Markovian Channels by Hierarchy Equation Method
Xiaolei Yin, Jian Ma, Xiaoguang Wang +1
We study spin squeezing under non-Markovian channels, and consider an ensemble of independent spin-1/2 particles with exchange symmetry. Each spin interacts with its own bath,…

Spin squeezing and concurrence
Xiaolei Yin, Xiaoqian Wang, Jian Ma +1
We study the relations between spin squeezing and concurrence, and find that they are qualitatively equivalent for an ensemble of spin-1/2 particles with exchange symmetry and pari…
