量子骰子

量子博弈是量子信息的一个重要分支.以Meyer所研究的单硬币博弈游戏为基础,主要讨论了具有六个态的骰子游戏.对于经典的二人骰子游戏而言,游戏者双方P和Q获胜的几率相同,都是1/2.而在量子骰子游戏中,用骰子的态密度矩阵来表示该态,若其中一个游戏者Q用量子策略来代替经典游戏中随机的翻转过程,而另一个游戏者P仍然采用经典策略,则Q完全可以控制游戏的胜负.从而对于量子骰子游戏而言,可以得出:量子策略比经典策略更具优越性.

Quantum dice

Quantum game is one of the important branches in quantum information.Based on the single- coin-tossing game studied by Meyer,the dice game which has six states is discussed.In classical dice game, the probabilities of two players,P and Q,to win the game are both equal to 1/2.In quantum dice game, each state of the dice can be denoted by its density matrix.And if the player Q adopts quantum strategies instead of classical ones while the other player P adopts the usual classical probabilistic strategies,Q can...
