It is constructed solely from linear optical elements and requires only a two-photon source for its demonstration. Its success probability is 1/9. Received 16 December 2001. WebFeb 27, 2004 · We demonstrate a robust implementation of a deterministic linear-optical Controlled-NOT (CNOT) gate for single-photon two-qubit quantum logic. A polarization Sagnac interferometer with an embedded 45 -oriented dove prism is used to enable the polarization control qubit to act on the momentum (spatial) target qubit of the same photon.
