Parrondo's paradox in quantum walks with time-dependent coin operators
Marcelo Amanajás Pires, Sı́lvio M. Duarte Queirós · Physical review. E · 2020
We show that a Parrondo paradox can emerge in two-state quantum walks without resorting to experimentally intricate high-dimensional coins. To achieve such goal we employ a time-dependent coin operator without breaking the translation spatial invariance of the system.
