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…

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…

Criterion for quantum Zeno and anti-Zeno effects
Jia-Ming Zhang, Jun Jing*, Li-Gang Wang +1
In this work, we study the decay behavior of a two-level system under the competing influence of a dissipative environment and repetitive measurements. The sign of the second deriv…
