So what’s quantum chess?

It’s a complicated version of regular chess that incorporates the quantum concepts of superposition, entanglement, and interference. “It’s like you’re playing in a multiverse but the different boards [in different universes] are connected to each other,” said Caltech physicist Spiros Michalakis during a livestream of the tournament. “It makes 3D chess from Star Trek look silly.”

Okay: Superposition: Elementary particles of our universe are not in one single specific place, they are only in a probable one.

Entanglement: What happens to one elementary particle affects any other particle entangled with it, no matter how far they are apart.

Interference: You can stop a quantum process by measuring it long enough (the quantum Zeno effect).

So quantum chess must be played by different rules.

Meanwhile, here’s Dr. Spock playing Charlie in Charlie X (1966): “Captain Kirk must learn the limits to the power of a 17-year-old boy with the psychic ability to create anything and destroy anyone.”

The fact that the spooky quantum world is real means that quantum computing could greatly reduce computers’ drastic environment impact.
