Round 10: Tossup 16

States with this physical property are often compared to a game in which Alice and Bob’s expected value increases due to the CHSH inequality. States with this property (10[1])were used in experiments by John Clauser and Anton Zeilinger. Successively applying Hadamard and CNOT (“C-not”) gates (-5[1])gives qubits this property. (10[2])Experiments on states with this property validated Bell’s theorem. (-5[1])States with this property (10[1])imply the existence of hidden variables according to the EPR paradox, which claims (10[1])it allows faster-than-light communication. (-5[1])For 10 points, name this property of quantum states that cannot be measured independently, (10[1])which Einstein called (10[1])“spooky action at a distance.” ■END■ (10[2]0[4])
