On Correlated Equilibria in Marinatto–Weber Type Quantum Games

“…To see how correlated equilibrium (26) in game (22) implies a Nash equilibrium in the MW approach to that game, consider the initial state |Ψ in (14) such that α ij = √ p ij for i = 0, 1 and j = 0, 1, 2. Then…”

“…In general, a large part of noncooperative quantum game theory is devoted to studying results of a quantum game by simply applying nonclassical moves, seeking rational strategy profiles among quantum strategies, and pointing out differences between classical and nonclassical solutions [10][11][12][13][14][15]. This paper presents a completely different approach.…”

“…In particular, the measurement can be identified with a payoff function. For example, in [19], the Authors studied the quantum Russian roulette with payoff functions…”

“…In this game each player, Alice and Bob for instance, has a qubit |ψ = c 1 |1 + c 2 |0 where |1 represents the "alive" state and |1 the "dead" state, and their only objective is to flip his/hers opponent's spin. Following this idea Schmidt and da Silva proposed the quantum version of the gamble known as Russian roulette, where players shoot themselves at point blank range using a gun loaded with just one bullet [19]. The authors found some interesting results concerning the cases where the gun was fully loaded as well as when there was just one quantum bullet inside its chambers.…”

“…It lies at the crossroads of physics, quantum information processing, computer and natural sciences. Various quantizations of games were presented by different authors [1][2][3][4][5].…”
