چکیده

Many previous works on quantum games are based on maximally entangled states. In this Letter, we investigate the correlations between entanglement and quantum games. For the particular case of the quantum prisoners’ dilemma, the property of the game changes fascinatingly with the variation of entanglement of the game’s state.  2001 Published by Elsevier Science B.V.

Playing Prisoner’s Dilemma with Quantum Rules

Quantum game theory is a recently developing field of physical research. In this paper, we investigate quantum games in a systematic way. With the famous instance of the Prisoner's Dilemma, we present the fascinating properties of quantum games in different conditions, i.e. different number of the players, different strategic space of the players and different amount of the entanglement involved.

درهم‌تنیدگی کوانتومی و گذار فاز کوانتومی تحت اتلاف در مدل ناهمسانگرد هایزنبرگ XXZ با برهم‌کنش ژیالوسینکی - موریا

  Because the key issue in quantum information and quantum computing is entanglement, the investigation of the effects of environment, as a source of quantum dissipation, and interaction between environment and system on entanglement and quantum phase transition is important. In this paper, we consider two-qubit system in the anisotropic Heisenberg XXZ model with the Dzyaloshinskii-moriya inter...

Quantum Non-Local Games

This work investigates upon the idea of using quantum entanglement in reference to non-local(NL) games. We begin with the definition of a non-local game and study it’s importance in context to the advantage gained over playing the game classically i.e. when no entanglement is involved. For certain NL games, like the XOR games, the gap between the value of the game(maximum success probability) p...

Darwinism in Quantum Systems?

We find quantum mechanics playing a role in evolutionary dynamics described by the notion of an Evolutionarily Stable Strategy (ESS). An ESS being a refinement of Nash equilibrium concept is a stable strategy in an evolutionary game with replicator dynamic as the underlying process. We investigate ESSs in two and three player symmetric quantum games played by the proposed scheme of applying ′id...

Thermal effect and role of entanglement and coherence on excitation transfer in a spin chain

We analyze the role of bath temperature, coherence and entanglement on excitation transfer in a spin chain induced by the environment. In Markovian regime, we show that coherence and entanglement are very sensitive to bath temperature and vanish in time in contrary to the case of having zero-temperature bath. That is while, finding the last qubit of the chain in excited state increases by incre...
