  We introduce a new board game based on the ancient Chinese game of Go (Weiqi,
Igo, Baduk). The key difference from the original game is that players no
longer alternatively play single stones on the board but instead they take
turns placing pairs of entangled go stones. A phenomenon of quantum-like
collapse occurs when one of the stones in an entangled pair is directly in
contact with at least one other stone. The player to whom the entangled pair
belongs must then remove one of the stones in the pair from the board. The aim
of the game is still to surround more territory than the opponent and as the
number of stones increases, all the entangled pairs of stones eventually reduce
to single stones. Quantum Go provides an interesting and tangible illustration
of quantum concepts such as superposition, entanglement and collapse.
