Utilizing encoding time as a resource to enhance quantum sensing by probe qubit dephasing
Ji-Bing Yuan, Hai-Fei Liu, Ya-Ju Song +3
We examine a system in which an impurity qubit is immersed in a quasi-two-dimensional dipolar Bose-Einstein condensate whose collective excitations act as a depasing reservoir for…

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…
