Probability and the Classical/Quantum Divide

  title={Probability and the Classical/Quantum Divide},
  author={Subhash C. Kak},
This paper considers the problem of distinguishing between classical and quantum domains in macroscopic phenomena using tests based on probability and it presents a condition on the ratios of the outcomes being the same (Ps) to being different (Pn). Given three events, Ps/Pn for the classical case, where there are no 3-way coincidences, is one-half whereas for the quantum state it is one-third. For non-maximally entangled objects ) 11 00 ( 1 1 2 + + = r r AA φ we find that so long as r < 5.83… CONTINUE READING
