Generating NOON states in circuit QED using multi-photon resonance in the presence of counter-rotating interactions
Shi-fan Qi, Jun Jing
The NOON states are valuable quantum resources, which have a wide range of applications in quantum communication, quantum metrology, and quantum information processing. Here we pro…
Quantumness protection for open systems in a double-layer environment
Yu-Long Qiao, Jia-Ming Zhang, Yusui Chen +2
We study the dynamics of the two-level atomic systems (qubits) under a double-layer environment that is consisted of a network of single-mode cavities coupled to a common reservoir…
Berry-phase-based quantum gates assisted by transitionless quantum driving
Shifan Qi, Jun Jing
We propose a novel proposal for geometric quantum gates using three- or two-level systems, in which a controllable variable, the detuning between the driving frequency and the atom…
Exact coherence dynamics mediated by a single cavity mode in the presence of leakage
Yusui Chen, Quanzhen Ding, Wufu Shi +2
We present a quantum-state-diffusion equation to characterize the dynamics of a generic atomic system coupled to a leaky cavity mode. As quantum resources, the population, the cohe…
Measurement-induced cooling of a qubit in structured environments
Jia-Ming Zhang, Jun Jing, Lian-Ao Wu +2
In this work, we study the thermodynamics of a two-level system (qubit) embedded in a finite-temperature structured-bath under periodical measurements. The system under measurement…
