Round 12: 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 (10[1])with this property were used in experiments by John Clauser and Anton Zeilinger. Successively applying Hadamard and CNOT (“C-not”) gates gives qubits this property. Experiments on states with this (10[1])property (10[1])validated Bell’s theorem. States with this property imply the (10[1])existence of hidden variables according to the EPR paradox, which claims it allows faster-than-light communication. (-5[1])For 10 points, name this property of quantum states that cannot be (10[1])measured independently, which Einstein called “spooky action (10[1])at a distance.” ■END■ (10[2]0[1])
