The unpredictable nature of quantum physics has been mimicked by Queen's University computer scientists to invent a new version of chess. In the quantum chess computer game created by undergraduate computer science student Alice Wismath, a piece that should be a knight could simultaneously also be a queen, a pawn or something else. The player doesn't know what the second state might be or which of the two states the piece will choose when it is moved. "It was very weird," said Ernesto Posse, a Queen's postdoctoral researcher who took part in a recent "quantum chess" tournament. "You only know what a piece really is once you touch the piece. Basically, planning ahead is impossible." Read the full article here.
