Quantum Chess provides an alternative to traditional chess ai which is based on branching, iterations, and historical plays databases. Instead Quantum Chess models each piece as a wave function between other pieces on the board allowing the discovery of optimal continuous paths. Please see the discussion page on where to begin. The theoretical advantage of Quantum Chess is that it automatically prunes redundant moves unlike iterative/branching models while maintaining strategy-like behavior completely unlike both chess AIs and humans. It is intended as an experiment to play against itself, and later to interface to other computers and humans. This should help form the basis for understanding real-world problems in a completely different way. Let this be an experiment into how we think about objects and waves as much as a viable ai chess alternative.
