‘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.’
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.
