Verification of Born's rule by a quantum mechanical meter

Born's postulate tells that the probability of state | Ψ〉 being found in | φ〉 is given by Born's rule: P φ| Ψ =|〈 φ| Ψ〉| 2. We consider a model of a meter which tests Born's rule. We show that the meter verifies Born's rule by assuming that P φ| Ψ →1 as |〈 φ| Ψ〉| 2→1....
