Catalytic Quantum Teleportation
Catalytic Quantum Teleportation
In this work, we address fundamental limitations of quantum teleportation---the process of transferring quantum information using classical communication and preshared entanglement. We develop a new teleportation protocol based upon the idea of using ancillary entanglement catalytically, i.e., without depleting it. This protocol is then used to show that catalytic entanglement …
