Parameter estimation with limited access of measurements
Jianning Li, Dianzhen Cui, X. X. Yi
Quantum parameter estimation holds the promise of quantum technologies, in which physical parameters can be measured with much greater precision than what is achieved with classica…
Effect of quantum jumps on non-Hermitian system
Xiangyu Niu, Jianning Li, S. L. Wu +1
One among the possible realizations of non-Hermitian systems is based on open quantum systems by omitting quantum jumping terms in the master equation. This is a good approximation…
Detecting the effects of quantum gravity with exceptional points in optomechanical sensors
Dianzhen Cui, T. Li, Jianning Li +1
In this manuscript, working with a binary mechanical system, we examine the effect of quantum gravity on the exceptional points of the system. On the one side, we find that the exc…
Cramér-Rao bound and quantum parameter estimation with non-Hermitian systems
Jianning Li, Haodi Liu, Zhihai Wang +1
The quantum Fisher information constrains the achievable precision in parameter estimation via the quantum Cramér-Rao bound, which has attracted much attention in Hermitian systems…
