چکیده انگلیسی:
Quantum teleportation as a key protocol for quantum communication and quantum computing demonstrates the
stark difference between quantum and classical information
transmission. An ideal teleportation protocol requires pure maximally entangled state as the teleportation channel, while in real
implementations the shared entanglement is severely degraded
due to decoherence. In this letter, we propose a scheme to
protect the quantum teleportation from decoherence by means
of environment assisted measurement with weak measurements
and flip operations. We show that the teleportation fidelity of
our proposed scheme is significantly improved compared to
teleportation with no protection and a teleportation protocol
based on quantum measurement reversal. Also, the explicit
formula of average teleportation fidelity and success probability
of the entanglement protection are derived.
