The parity game is an example of a nonlocal game: by sharing a Greenberger-Horne-Zeilinger (GHZ) state before playing this game, the players can win with a higher probability than is allowed by classical physics. The GHZ state of N qubits is also the ground state of the ferromagnetic quantum Ising model on N qubits in the limit of vanishingly weak quantum ﬂuctuations. Motivated by this observation, we examine the probability that N players who share the ground state of a generic quantum Ising…

Nonlocal games yield an unusual perspective on entangled quantum states. The deﬁning property of such games is that a set of players in joint possession of an entangled state can win the game with…

An upper bound on the best possible classical strategy for attempting to play this game is proved, as well as a novel, matching lower bound on how well imperfect quantum-mechanical apparatus must perform in order to exhibit a behaviour that would be classically impossible to explain.

The basic building block of quantum computation is the qubit, a system with two (nearly)
degenerate states that can be used to encode quantum information. Real systems typically

If the nine distinct probability distributions that are generated by the self checking configuration, one for each pair of angles, are consistent with the specifications, the source and the two measurement apparatus are guaranteed to be identical to the claimed specifications up to a local change of basis on each side.
