Chess Becomes Harder: Thanks to Quantum Physics

Adding a twist to the normal Chess game using the uncertainty of the Quantum Mechanics makes thing more difficult.Queen's University computer scientists have invented a new version of chess where its nearly impossible to predict the nature of a piece before hand. As soon as the player touches the piece it assumes is new behavior.


'You only know what a piece really is once you touch the piece,' researcher Ernesto Posse said after he tried the game. 'Basically, planning ahead is impossible.'

Quantum quirks
According to quantum physics, very small particles behave according to principles that give them characteristics very different from the behaviour of larger objects. Here are a few properties of those quantum objects:
> Quantum superposition: A quantum object may exist in multiple states at the same time.
> Wave function collapse: An observer's interaction with a quantum object in a superposition of states, such as an attempt to measure its position or momentum, will make it "collapse" into a single state.
> Quantum entanglement: Two or more quantum objects may be linked so that any change to one is immediately experienced by another, no matter how far apart they are from one another.
