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 Course a pied - Homme - Vetements - Manteau - Duvet discuss the use of this device in a two-qubit quantum game.When entanglement is Circle Pendant With Birthstone Beads Necklace absent, the maximum quantum advantage in this game is 1/3 bit.A slightly diminished quantum advantage, 0.

311 bit, can be realized with a simplified transaction protocol.
