Quantum Measurement and Bell’s Theorem
The concept of measurement favoured by Einstein, Bohm, Putnam, et al. in the context of Quantum Theory (QT) is a realist concept. It encapsulates the realist idea that in measurement we are about the task of reporting an independently existing objective reality. Moreover for Einstein, Bohm, Putnam et al. this objective reality is to be characterised classically in terms of physical quantities possessing particular values.1 Thus an “ideal measurement” is characterised as a process in which a measured value for some physical quantity is produced and that measured value reflects the value possessed by the physical quantity.
