Universal shot-noise limit for quantum metrology with local Hamiltonians
Hai-Long Shi, Xi-Wen Guan, Jing Yang
Quantum many-body interactions can induce quantum entanglement among particles, rendering them valuable resources for quantum-enhanced sensing. In this work, we derive a universal…
Microscopic origin of quantum supersonic phenomenon in one dimension
Zhe-Hao Zhang, Yuzhu Jiang, Hai-Qing Lin +1
Using the Bethe ansatz (BA), we rigorously obtain non-equilibrium dynamics of an impurity with a large initial momentum in the one-dimensional (1D) interacting bosonic medium.…
Scaling of energy and power in a large quantum battery-charger model
Lei Gao, Chen Cheng, Wen-Bin He +3
We investigate a multi-qubit quantum battery-charger model, focusing on its potential emulation on a superconducting qubit chip. Using a large-spin representation, we first obtain…
Finite-time stabilization control of quantum systems
Sen Kuang, Xiaoke Guan, Daoyi Dong
The finite-time control problem of quantum systems is investigated in this paper. We first define finite-time stability and present a finite-time Lyapunov stability criterion for f…
