Temperature-enhanced quantum sensing for the cutoff frequency of Ohmic environments
Yuan Ji-Bing, Song Ya-Ju, Tang Shi-Qing +2
We investigate the quantum sensing performance of a dephasing qubit as a probe in Ohmic environments, characterized by the coupling strength , the Ohmicity parameter , and th…
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…
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…
Controlling decoherence speed limit of a single impurity atom in a Bose-Einstein-condensate reservoir
Ya-Ju Song, Le-Man Kuang
We study the decoherence speed limit (DSL) of a single impurity atom immersed in a Bose-Einsteincondensed (BEC) reservoir when the impurity atom is in a double-well potential. We d…
Quantum speed-up of multiqubit open system via dynamical decoupling pulses
Ya-Ju Song, Qing-Shou Tan, Le-Man Kuang
We present a method to accelerate the dynamical evolution of multiqubit open system by employing dynamical decoupling pulses (DDPs) when the qubits are initially in W-type states.…
Impurity-induced Dicke quantum phase transition in an impurity-doped cavity-Bose-Einstein condensate
Ji-Bing Yuan, Ya-Ju Song, Le-Man Kuang
We present a new generalized Dicke model, an impurity-doped Dicke model (IDDM), by the use of an impurity-doped cavity-Bose-Einstein condensate. It is shown that the impurity atom…
