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…
Absence of collapse in quantum Rabi oscillations
Shu He, Yang Zhao, Qing-Hu Chen
We show analytically that the collapse and revival in the population dynamics of the atom-cavity coupled system under the rotating wave approximation (RWA), valid only at very weak…
Generalized rotating-wave approximation to the two-qubit and cavity coupling system
Yu-Yu Zhang, Qing-Hu Chen
The generalized rotating-wave approximation (GRWA) is presented for the two-qubit and cavity coipling system . The analytical expressions in the zeroth order approximation recover…
Genuine Multipartite Entanglement of Superpositions
Zhihao Ma, Zhihua Chen, Shao-Ming Fei
We investigate how the genuine multipartite entanglement is distributed among the components of superposed states. Analytical lower and upper bounds for the usual multipartite nega…
Multiple phase estimation for arbitrary pure states under white noise
Yao Yao, Li Ge, Xing Xiao +2
In any realistic quantum metrology scenarios, the ultimate precision in the estimation of parameters is limited not only by the so-called Heisenberg scaling, but also the environme…
Quantum metrology with unitary parametrization processes
Jing Liu, Xiaoxing Jing, Xiaoguang Wang
Quantum Fisher information is a central quantity in quantum metrology. We discuss an alternative representation of quantum Fisher information for unitary parametrization processes.…
