Abstract

The concept of nonseparability between spin and orbital degrees of freedom of laser modes is applied in the implementation of the quantum prisoners dilemma. The quantum version of the game brings novel features with a richer universe of strategies and is one of the basic examples to illustrate the concepts of game theory. Exploiting the classical paraxial spin–orbit modes, we implemented the most important strategies that can be achieved in the quantum version of the game.

Playing a quantum game on polarization vortices

The quantum mechanical approach to the well known prisoners dilemma, one of the basic examples to illustrate the concepts of Game Theory, is implemented with a classical optical resource, nonquantum entanglement between spin and orbital degrees of freedom of laser modes. The concept of entanglement is crucial in the quantum version of the game, which brings novel features with a richer universe of strategies. As we show, this richness can be achieved in a quite unexpected context, namely that of paraxial spin-orbit modes in classical optics.

Experimental Implementation of Quantum Prisoner Dilemma on IBM Quantum Computers

Kanyangzi Xu, Zhe Wu

Theory of games is an important discipline of applied mathematics, which has found numerous applications in psychology, ecology, and social science. While a well-established framework has been established for classical game theory, extending, and generalizing it towards the quantum domain still has some open questions. In this project, we focus on the prisoner’s dilemma-a standard example of a game analyzed in game theory-in a quantum world. Here, we start with the quantum version of prisoner’s dilemma, explain the quantum circuit implementation for describing the behavior of quantum prisoners, and investigate how quantum entanglement can change their strategies. By using the IBM quantum computer, we experimentally study the quantum prisoner dilemma, and we conclude that the best quantum strategies will break the prisoner’s dilemma.

Quantum Game Theory

Zibo Wang

Game theory has wide implementation on many fields of study. With more recent development in quantum computation and quantum information, we are able to study games with rule of quantum mechanics. This paper consists two part: in first part, basic knowledge of game theory is briefly recalled, and prisoner’s dilemma is introduced; in second part, how quantum version game is differ from classical is discussed, and an analysis quantum version of prisoner’s dilemma is presented.

On the justification of applying quantum strategies to the Prisoners' Dilemma and mechanism design

Haoyang Wu

The Prisoners' Dilemma is perhaps the most famous model in the field of game theory. Consequently, it is natural to investigate its quantum version when one considers to apply quantum strategies to game theory. There are two main results in this paper: 1) The well-known Prisoners' Dilemma can be categorized into three types and only the third type is adaptable for quantum strategies. 2) As a reverse problem of game theory, mechanism design provides a better circumstance for quantum strategies than game theory does.

How Quantum Prisoner’s Dilemma Can Support Negotiations

M. Szopa

Decision-making by the two negotiating parties is simulated by a prisoner's dilemma game.The game is formulated in a quantum manner, where players strategies are unitary transformations of qubits built over the basis of opposite decision options.Quantum strategies are correlated through the mechanism of quantum entanglement and the result of the game is obtained by the collapse of the resulting transformed state.The range of strategies allowed for quantum players is richer than in case of a classical game and therefore the result of the game can be better optimized.On the other hand, the quantum game is save against eavesdropping and the players can be assured that this type of quantum arbitration is fair.We show that quantum prisoner's dilemma has more favorable Nash equilibria than its classical analog and they are close to the Pareto optimal solutions.Some economical examples of utilizing quantum game Nash equilibria are proposed.

Playing Games with Quantum Mechanics

Simon J. D. Phoenix, Faisal Shah Khan

We present a perspective on quantum games that focuses on the physical aspects of the quantities that are used to implement a game. If a game is to be played, it has to be played with objects and actions that have some physical existence. We call such games playable. By focusing on the notion of playability for games we can more clearly see the distinction between classical and quantum games and tackle the thorny issue of what it means to quantize a game. The approach we take can more properly be thought of as gaming the quantum rather than quantizing a game and we find that in this perspective we can think of a complete quantum game, for a given set of preferences, as representing a single family of quantum games with many different playable versions. The versions of Quantum Prisoners Dilemma presented in the literature can therefore be thought of specific instances of the single family of Quantum Prisoner's Dilemma with respect to a particular measurement. The conditions for equilibrium are given for playable quantum games both in terms of expected outcomes and a geometric approach. We discuss how any quantum game can be simulated with a classical game played with classical coins as far as the strategy selections and expected outcomes are concerned.
