Using quantum Parrondo’s random walks for encryption

Assistant Professor Kang Hao Cheong and his research team from the Singapore University of Technology and Design (SUTD) have set out to apply concepts from quantum Parrondo’s paradox in search of a working protocol for semiclassical encryption. In a recent Physical Review Research letter, the team published the paper “Chaotic switching for quantum coin Parrondo’s games with application to encryption’ and discovered that chaotic switching for quantum coin Parrondo’s games has similar underlying ideas and working dynamics to encryption.
