    • 2015, Shan Gao, Protective Measurement and Quantum Reality, →ISBN, page 42:
      We would like now to show that the counterpart of the conditional probability ℘(jǀk) in quantum mechanics is indeed the probability of a final detection event, which, given a certain experimental context (a premeasurement), allows us to finally ascribe a property to the object system (the system that has been measured).
