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…
Energy Optimal Control for Quantum System Evolving on SU(1,1)
Jian-Wu Wu, Chun-Wen Li, Jing Zhang +1
This paper discusses the energy optimal control problem for the class of quantum systems that possess dynamical symmetry of SU(1,1), which are widely studied in various physical pr…
Controllability of Quantum Systems on the Lie Group SU(1,1)
Jian-Wu Wu, Chun-Wen Li, Jing Zhang +1
This paper examines the controllability for quantum control systems with SU(1,1) dynamical symmetry, namely, the ability to use some electromagnetic field to redirect the quantum s…
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…
