Realizing quantum advantage without entanglement in single-photon states

We propose an optical circuit for attaining quantum measurement advantage in a system that has no quantum entanglement. Our device produces symmetric two-qubit X-states with controllable anti-diagonal elements, and does not require entangled states as input. We discuss the use of this device in a tw...
