Instantaneous indirect measurement principle in quantum mechanics
Wangjun Lu, Xingyu Zhang, Lei Shao +6
In quantum systems, the measurement of operators and the measurement of the quantum states of the system are very challenging tasks. In this Letter, we propose a method to obtain t…
Extreme expected values and their applications in quantum information processing
Wangjun Lu, Lei Shao, Xingyu Zhang +4
We consider the probability distribution when the monotonic function of the independent variable takes the maximum or minimum expected value under the two constraints of…
Optimal state for a Tavis-Cummings quantum battery via the Bethe ansatz method
Wangjun Lu, Jie Chen, Le-Man Kuang +1
In this paper, we investigate the effect of different optical field initial states on the performance of the Tavis-Cummings (T-C) quantum battery. In solving the dynamical evolutio…
Charging of quantum batteries with general harmonic power
Jie Chen, Liyao Zhan, Lei Shao +3
We analyse the charging process of quantum batteries with general harmonic power. To describe the charge efficiency, we introduce the charge saturation and the charging power, and…
Quantum Fisher information and symmetric logarithmic derivative via anti-commutators
Jing Liu, Jie Chen, Xiao-Xing Jing +1
Symmetric logarithmic derivative (SLD) is a key quantity to obtain quantum Fisher information (QFI) and to construct the corresponding optimal measurements. Here we develop a metho…
