Non-Hermitian-enhanced quantum sensing in an optical interferometer
X. J. Huang, Lei Xiao, Bingzi Huo +2
The precision of quantum parameter estimation is traditionally constrained by the quantum Cramér-Rao bound, which is based on the Hermitian measurement framework. Recent studies of…
Quantum sensing of aging transitions
Huining Zhang, Yunbo Zhang, Xiaoguang Wang +1
The aging transition is a critical phenomenon in which collective dynamics deteriorate as the fraction of inactive quantum nodes exceeds a threshold, referred to as the aging trans…
Aging of coupled qubits
Huining Zhang, Dianzhen Cui, W. Wang +1
The aging transition refers to the shift from an oscillatory state to a globally ceased state due to some forms of deterioration in classical physics. Similar behavior has also bee…
Agnostic Parameter Estimation with Large Spins
Huining Zhang, X. X. Yi
The quantum Fisher information of a quantum state with respect to a certain parameter quantifies the sensitivity of the quantum state to changes in that parameter. Maximizing the q…
Manipulating spectral transitions and photonic transmission in a non-Hermitian optical system through nanoparticle perturbations
Bo-Wang Zhang, Cheng Shang, J. Y. Sun +2
In recent years, extensive research has been dedicated to the study of parity-time () symmetry, which involves the engineered balance of gain and loss in non-Hermitia…
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…
