Experimental Demonstration of Deterministic Entanglement Transformation

According to Nielsen's theorem Phys.Rev.Lett. 83(1999)436 and as a proof of principle, we demonstrate the deterministic transformation from a maximum entangled state to an arbitrary nonmaximum entangled pure state with local operation and classical communication in an optical system. The output states are verified with a quantum tomography process. We further test the violation of Bell-like inequality to demonstrate the quantum nonlocality of the state we generated. Our results may be useful in quantum information processing.
