量子围棋中文简介

未名量子围棋是根据吴飙、陈汉博、罗智康的理论[arXiv: 2004.08272; Science China Information Science 64 (2021) 122501]设计的。这个理论的基本原则是：（1）尽量保留围棋的特征；（2）充分利用量子力学的态叠加原理来丰富围棋的步法；（3）保证量子计算机能下这个围棋，就像现在的经典计算机可以自己下围棋一样。根据这些原则设计的量子围棋最后等效于两个棋手在同时下多盘相互关联的围棋。

量子计算机原理对围棋的吃子规则产生的改变是最大的。如果严格按照量子计算机的原理，黑方在一个棋盘上吃掉一颗白子必须在其它棋盘上相同位置放上一颗白子，反之亦然。这样，吃掉对方棋子的同时需要在其它棋盘上为对方下子。这和普通的围棋反差太大。由于这个原因，我们在设计未名围棋时采取了一个折中方案：如果对方的第n步下的棋子在一个棋盘上被吃了，在其它棋盘上第n步下的棋子也被吃。

Quantum Weiqi (or Go) 

Weiming quantum Weiqi is based on the quantum theory of board games by Biao Wu, Hanbo Chen, and Zhikang Luo[arXiv: 2004.08272; Science China Information Science 64 (2021) 122501]. The aim of this theory is to ensure that (1) the classical game of Weiqi (or go) is a special case; (2) there are new moves based quantum superposition principle; (3) quantum computer can play this game just like the classical computer can play the conventional Weiqi (or go). The result is that two players play multiple correlated Weiqi games simultaneously.
The capture of stone is mostly affected by the basic principles of quantum computer. To strictly follow the principles, one has to design the following rule for capture: if the black captures one white stone in one game, then white stones have to be placed at the same position in other games; vice versa.  This means that while capturing the opponent’s stones in one game, one has to place the opponent’s stones in other games. This is radically different from the conventional game of Weiqi. In Weiming quantum Weiqi, we have adopted a compromise: if the stone placed by the opponent in the nth step is captured in one game, it is also captured in other games.
