Remote state preparation with classically correlated state

We experimentally demonstrate the first remote state preparation with no shared entanglement, employing classically correlated state (CCS). CCS is verified with quantum state tomography process, and the fidelity is 0.99. The states chosen from a special diameter of the Poincaré sphere can be remotely prepared with unit efficiency at the cost of one cbit, if one classically correlated state is shared. The scheme can remotely prepare the other states on the Poincaré sphere with other CCS using the same experimental setup. The efficiency is 50% in general.
