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.…
