Historically, quantum measurement systems do not associate any system certainty with measurement, only the probability of outcomes. Is every quantum measurement 100% certain? The photon is counted or not. The spin is up or down. We know quantum is a probabilistic theory yet try and fail to make sense of quantum using only the non-probabilistic classical information.
Quantum measurement systems do have quantum system certainty (QSC) associated with measurements as a f(Θ). Further, this QSC is quantized for each event, 100% certain or 0% certain, one or the other, never both. A photon polarized at Θa has a probability of QSC as a f(Θa, Θ) and a spin measurement of up at Θb has a probability of QSC as a f(Θb, Θ). It’s very interesting the QSC f(Θ) is the same whether counting photons or measuring spin. The quantum system certainty will be presented which, by introducing the same probability of the QSC onto the polarization of the photon or spin measurement, provides enhanced clarity to quantum measurement.
