  title={Comment on "Quantum Games and Quantum Strategies"},
  author={Anthony Bordg and Yijun He},
We point out a flaw in the unfair case of the quantum Prisoner's Dilemma as introduced in the pioneering Letter "Quantum Games and Quantum Strategies" of Eisert, Wilkens and Lewenstein. It is not true that the so-called miracle move therein always gives quantum Alice a large reward against classical Bob and outperforms tit-for-tat in an iterated game. Indeed, we introduce a new classical strategy that becomes Bob's dominant strategy, should Alice play the miracle move. Finally, we briefly… 
Quantum Conditional Strategies for Prisoners' Dilemmata Under the Ewl Scheme
This work examines some well-known game conditional strategies that have been studied within the framework of the repeated PD game and tries to associate these strategies to proper quantum finite automata that receive them as inputs and recognize them with probability 1, achieving some interesting results.
Quantum Games and Entanglement as a Resource
Bell’s seminal paper [2] firmly established the non-local nature of quantum mechanics, disproving the existence of local hidden variable theories. This paved the way for understanding entanglement as
A Review of Quantum Games
The accuracy of a few simple quantum games has been supported with experimental evidence through computer science, suggesting the potential relevance of the theory once necessary technological advances are made.
2 00 3 Quantum duels and truels
A truel, or three person generalization of a duel, is a popular model in game theory of a struggle for survival. The outcome is often sensitive to the precise rules under which the truel is performed

Finite Automata Capturing Winning Sequences for All Possible Variants of the PQ Penny Flip Game
This paper establishes a rigorous connection between finite automata and the P Q game along with all its possible variations, and introduces the new concepts of a winning automaton and complete automaton for either player.

We study a general 2 × 2 symmetric entangled quantum game. When one player has access only to classical strategies, while the other can use the full range of quantum strategies, there are ‘miracle’
Quantum Games and Quantum Strategies
We investigate the quantization of non-zero sum games. For the particular case of the Prisoners' Dilemma we show that this game ceases to pose a dilemma if quantum strategies are allowed for. We also
Quantum strategies
It is proved that in general a quantum strategy is always at least as good as a classical one, and furthermore that when both players use quantum strategies there need not be any equilibrium, but if both are allowed mixed quantum strategiesthere must be.
