TLDR
In this paper, the quantum prisoners dilemma was implemented in the quantum version of the game and the classical paraxial spin and orbital spin-orbit modes were exploited to implement the most important strategies.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.read more

Using the nonseparability of vector beams to encode information for optical communication
TL;DR: It is shown that 2 bits of information can be encoded when applying the identity and three Pauli operators to its polarization degree of freedom, and that vector beams can be efficiently decoded with as low as 2.7% cross talk.

TL;DR: In this article, the authors demonstrate electromagnetic quantum states of single photons and of correlated photon pairs exhibiting hybrid entanglement between spin and orbital angular momentum, obtained from entangled photon pairs emitted by spontaneous parametric down conversion.

Entanglement beating in free space through spin-orbit coupling.
TL;DR: Using local Bell states engineered from classical vector vortex beams with non-separable degrees of freedom, the so-called classically entangled states, it is demonstrated that the entanglement evolves during propagation, oscillating between maximally entangled and product states (purely scalar).

Quantum games: a review of the history, current state, and interpretation
TL;DR: This work reviews both theoretical and experimental developments in the area of quantum games since the inception of the subject circa 1999 and offers a narrative on the controversy that surrounded the subject in its early days.

Astigmatic laser mode converters and transfer of orbital angular momentum
TL;DR: In this paper, a mode converter based on the Gouy phase was proposed to transform a Hermite-gaussian mode of arbitrarily high order to a Laguerre-Gaussian mode and vice versa.

Quantum Games and Quantum Strategies
TL;DR: In this article, the authors investigated the quantization of nonzero sum games and showed that the Prisoners' Dilemma does not pose a dilemma if quantum strategies are allowed for, and constructed a particular quantum strategy which always gives reward if played against any classical strategy.
Journal ArticleDOI
Quantum strategies
TL;DR: 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.
