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…
Effect of atom-oscillator interaction on the aging transition in coupled oscillators
Huining Zhang, X. Z. Hao, X. X. Yi
Oscillators are often employed as a model of radiation fields, which may couple to an atom and play an important role for creating and manipulating nonclassical states in quantum m…
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…
