Antisymmetry-breaking-coupling-enhanced sensing of quantum reservoirs
Ji-Bing Yuan, Zhi-Min Tang, Ya-Ju Song +4
We investigate the utilization of a single generalized dephasing qubit for sensing a quantum reservoir, where the antisymmetric coupling between the qubit and its reservoir is brok…

Atomic and photonic entanglement concentration via photonic Faraday rotation
Zhao-Hui Peng, Jian Zou, Xiao-Juan Liu +2
We propose two alternative entanglement concentration protocols (ECPs) using the Faraday rotation of photonic polarization. Through the single-photon input-output process in cavity…
