Quantum strategies
... 6 |T i. Then Picard can improve his expected payoff (to 1) by changing his strategy, replacing U2 with U3−1 F U1−1 , which is unitary since each of U1 , U3 and F is. Since U3 U2 U1 |Hi cannot be both |Hi and |T i, at least one of the players can improve his expected payoff by changing his strategy w ...

Quantum Teleportation Between Discrete and Continuous
... distinguished by simply projecting mode A onto the singlephoton state. Indeed, a photon detection event cannot happen in response to states (6b). Furthermore, state jΦþ i transforms into a positive cat state, whose Fock decomposition for a small α contains primarily the vacuum state. The negative ca ...
