Deterministic Controlled-NOT gate for single-photon two-qubit quantum logic
arXiv:quant-ph/0402208 · doi:10.1103/PhysRevLett.93.070502
Abstract
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. The CNOT 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.
