Buzek}, title = {Quantum Parrondo{\textquoteright}s game with random strategies}, abstract = {We present a quantum implementation of Parrondo{\textquoteright}s game with randomly switched strategies using (1) a quantum walk as a source of {\textquoteright}randomness{\textquoteright} and (2) a completely positive (CP) map as a randomized evolution. The game exhibits the same paradox as in the classical setting where a combination of two losing strategies might result in a winning strategy. We show that the CP-map scheme leads to significantly lower net gain than the quantum-walk scheme.}, year = {2007}, journal = {Journal of Modern Optics}, volume = {54}, number = {13-15}, pages = {2275{\textendash}228}, month = {9}, language = {eng}, }
