Suppressing non-Markovian noises by coupling the qubit to a chaotic device
Jing Zhang, Yu-xi Liu, Wei-Min Zhang +2
To suppress decoherence of solid-state qubits which are coupled to the non-Markovian noises, we propose a strategy to couple the qubit with a chaotic device, of which the broad pow…
Cooling and squeezing the fluctuations of a nanomechanical beam by indirect quantum feedback control
Jing Zhang, Yu-xi Liu, Franco Nori
We study cooling and squeezing the fluctuations of a nanomechanical beam using quantum feedback control. In our model, the nanomechanical beam is coupled to a transmission line res…
Protecting entanglement in superconducting qubits
Jing Zhang, Yu-xi Liu, Chun-Wen Li +2
When a two-qubit system is initially maximally-entangled, two independent decoherence channels, one per qubit, would greatly reduce the entanglement of the two-qubit system when it…
Using squeezed field to preserve two-atom entanglement against spontaneous emissions
Jing Zhang, Re-Bing Wu, Chun-Wen Li +1
Tunable interaction between two atoms in a cavity is realized by interacting the two atoms with an extra controllable single-mode squeezed field. Such a controllable interaction ca…
Asymptotically noise decoupling for Markovian open quantum systems
Jing Zhang, Re-Bing Wu, Chun-Wen Li +2
The noise decoupling problem is investigated for general N-level Markovian open quantum systems. Firstly, the concept of Cartan decomposition of the Lie algebra is introduc…
Quasi multipartite entanglement measure based on quadratic functions
Jing Zhang, Chun-Wen Li, Re-Bing Wu +2
We develop a new entanglement measure by extending Jaeger's Minkowskian norm entanglement measure. This measure can be applied to a much wider class of multipartite mixed states, a…
