Single-photon control and target qubits were mixed with a single ancilla photon in a device constructed using only linear optical elements. The successful operation of the controlled-NOT gate relied on post-selected three-photon interference effects, which required the detection of the photons in the output modes.4 pagesen-USThis item is likely protected under Title 17 of the U.S. Copyright Law.
