In this article, the operation and tolerances of a quantum controlled-NOT gate for photonic qubits are described and a two-photon source is used for its demonstration.
Abstract
We describe the operation and tolerances of a nondeterministic, coincidence basis, quantum controlled-NOT gate for photonic qubits. It is constructed solely from linear optical elements and requires only a two-photon source for its demonstration. Its success probability is 1/9.
