Environment-mediated quantum state transfer

Year: 2008

Type: article

Abstract: We propose a scheme for quantum state transfer (QST) between two qubits, which is based on their individual interaction with a common boson environment. The corresponding single-mode spin-boson Hamiltonian is solved by mapping it into a wave propagation problem in a semi-infinite ladder and the fidelity is obtained. High fidelity occurs when the qubits are equally coupled to the boson while the fidelity becomes smaller for nonsymmetric couplings. The complete phase diagram for such an arbitrary QST mediated by bosons is discussed.
