Chaotic switching for quantum coin Parrondo's games with application to encryption
Joel Weijia Lai, Kang Hao Cheong · Physical Review Research · 2021
Quantum game theory has stimulated some interest in recent years with the advancement of quantum information theory.This interest has led to a resurgence of quantum Parrondo's games.With two losing games combining to give a winning game, this paradoxical idea is known as Parrondo's paradox.By using chaotic switching between the two losing quantum games, we show that it is possible to achieve Parrondo's paradox involving a quantum walker playing two-sided quantum coin tossing games.Furthermore, we show that the framework of chaotic switching in quantum coin tosses can be applied to encryption.This is a proposal to deploy a quantum coin toss with chaotic switching for semiclassical encryption.
