Deterministic remote preparation of pure and mixed polarization states

We propose a deterministic remote state preparation scheme for photon polarization qubit states, where entanglement, local operations, and classical communication are used. By consuming one maximally entangled state and two classical bits, an arbitrary (either pure or mixed) qubit state can be prepared deterministically at a remote location. We experimentally demonstrate the scheme by remotely preparing $12$ pure states and $6$ mixed states. The fidelities between the desired and achieved states are all higher than $0.99$ and have an average of $0.9947$.
