Quantum Remote Control of Unitary Operations on a Qubit of Pure Entangled States
Chunmei Yao · Chinese Physics Letters · 2006
We consider the remote implementation of an arbitrary unitary operation on one qubit of a pure two-qubit entangled state with 100% efficiency via entanglement swapping in detail, then directly generalize this protocol from two-qubit to N -qubit entangled states. The overall classical information and distributed entanglement cost required for this quantum remote control protocol is less than the bi-directional quantum state teleportation method.
