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…

Quantum sensing of temperature close to absolute zero in a Bose-Einstein condensate
Ji-Bing Yuan, Bo Zhang, Ya-Ju Song +3
We propose a theoretical scheme for quantum sensing of temperature close to absolute zero in a quasi-one-dimensional Bose-Einstein condensate (BEC). In our scheme, a single-atom im…
