Environment-assisted entanglement restoration and improvement of the fidelity for quantum teleportation |
Abstract | ||
|---|---|---|
Three environment-assisted schemes are proposed to suppress the amplitude damping decoherence for entanglement distribution via weak measurement reversal. Based on the measurement of environment and appropriate weak measurement reversal operations, the initial entangled state can be recovered between two separated participants with high success probability and fidelity. In some specific cases, the restored optimal concurrence could reach up to 1 without requirement of the reversing measurement. Moreover, we concretely show that the proposed environment-assisted entanglement restoration can be applied to quantum teleportation to significantly improve the fidelity of the teleported state. |
