摘要：

We demonstrate a robust implementation of a deterministic linear-optical controlled-NOT Gate for single-photon two-qubit quantum logic. A polarization Sagnac interferometer with an embedded 45 degrees-oriented dove prism is used to enable the polarization control qubit to act on the momentum (spatial) target qubit of the same photon. The optical controlled-NOT gate requires no active stabilization because the two spatial modes share a common path, and it is used to entangle the polarization and momentum qubits.
