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 a pure maximally entangled state as the teleportation channel, while in real implementations the shared entanglement is severely degraded due to decoherence. In this talk, I will demonstrate how the utilization of weak measurement and environment-assisted measurement can enhance the performance of teleportation in the presence of noise to a considerable extent.
