Quantum teleportation with partially entangled joint measurements induced by coherent errors
This work addresses how coherent errors in joint measurements degrade quantum teleportation fidelity. The authors introduce a measurement-reversal framework that allows for recovering unit teleportation fidelity even when the joint measurements are only partially entangled due to these errors. It shows that optimizing performance requires balancing channel entanglement, measurement entanglement, and their relative basis alignment.
