Trapping quantum coherence with a dissipative thermal bath
Jia-Ming Zhang, Bing Chen, Jun Jing
In the long-time limit, an open quantum system coupled to a dissipative environment is believed to lose its coherence without driving or measurement. Counterintuitively, we provide…
Robust Multiple-Range Coherent Quantum State Transfer
B. Chen, Y. D. Peng, Y. Li +1
We propose a multiple-range quantum communication channel to realize coherent two-way quantum state transport with high fidelity. In our scheme, an information carrier (a qubit) an…
An impurity-induced gap system as a quantum data bus for quantum state transfer
Bing Chen, Yong Li, Z. Song +1
We introduce a tight-binding chain with a single impurity to act as a quantum data bus for perfect quantum state transfer. Our proposal is based on the weak coupling limit of the t…
Long-range adiabatic quantum state transfer through a tight-binding chain as a quantum data bus
Bing Chen, Wei Fan, Yan Xu +3
We introduce a scheme based on adiabatic passage that allows for long-range quantum communication through tight-binding chain with always-on interaction. By adiabatically varying t…
Long-range adiabatic quantum state transfer through a linear array of quantum dots
Bing Chen, Q. H. Shen, Wei Fan +1
We introduce an adiabatic long-range quantum communication proposal based on a quantum dot array. By adiabatically varying the external gate voltage applied on the system, the quan…
Quantum phase transition of two-mode Bose-Einstein condensates with an entanglement order parameter
Wei Fan, Yan Xu. Bing Chen, Zhaoyang Chen +2
The ground state entanglement of the two-mode Bose-Einstein condensate is investigated through a quantum phase transition approach. The entanglement measure is taken as the order p…
