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…
Quantum-state transfer between atom and cavity field in Jaynes-Cummings model
G. Zhang, G. R. Li, Z. Song
We present a scheme for transferring quantum state between atom and cavity field in Jaynes-Cummings model. It is based on the fact that the atom in a cavity can induce the generati…
Asymmetric coherent transmission for single particle diode and gyroscope
S. Yang, Z. Song, C. P. Sun
We study the single particle scattering process in a coherent multi-site system consisting of a tight-binding ring threaded by an Aharonov-Bohm flux and several attaching leads. Th…
Quantum entanglement of two flux qubits induced by an auxiliary SQUID
T. Shi, Z. Song
We revisit a theoretical scheme to create quantum entanglement of two three-levels superconducting quantum interference devices (SQUIDs) with the help of an auxiliary SQUID. In thi…
Dynamic generation of entangling wave packets in XY spin system with decaying long range couplings
S. Yang, Z. Song, C. P. Sun
We study the dynamic generation of spin entanglement between two distant sites in an XY model with -decay long range couplings. Due to the linear dispersion relation $ε(k)…
Quantum state swapping via qubit network with Hubbard interaction
S. Yang, Z. Song, C. P. Sun
We study the quantum state transfer (QST) in a class of qubit network with on-site interaction, which is described by the generalized Hubbard model with engineered couplings. It is…
