Quantum Parrondo ’ s games

  title={Quantum Parrondo ’ s games},
  author={A. P. Flitneya and J. H. C. Nga and D. Abbotta},
Parrondo’s paradox arises when two losing games are combined to produce a winning one. A history-dependent quantum Parrondo game is studied where the rotation operators that represent the toss of a classical biased coin are replaced by general SU (2) operators to transform the game into the quantum domain. In the initial state, a superposition of qubits can be used to couple the games and produce interference leading to quite di.erent payo.s to those in the classical case. c © 2002 Elsevier… CONTINUE READING
