FQxI Physics

Congratulations to William Wong, who won the FQxI challenge at the @Moth_Quantum hack. We asked entrants to teach a general audience something about quantum physics, using Moth’s Atlas engines. William made Quantum Crew, a party game where two teams try to keep a space station running without talking to each other. However carefully they plan, they can’t get more than 75% of rounds right. Give each pair a set of entangled crystals and they reach about 85%. Physicists use this kind of test to show that entangled particles can’t just be carrying instructions set in advance. We also liked that the game shows what entanglement can’t do: the crystals never let the players send each other a message.
