Time in Quantum Measurement

Abstract

Based on a model of quantum measurement we derive an estimate for the external measurement-time. Some interesting consequences will be analyzed.

A Model of Time

“…This way we would derive models of spin -time or polarisation -time. Note, however, that it follows from our estimates in [8] that it is the fact that the space dimension is three, n = 3, which leads to the possibility of constant velocity and ultimately to an absolute bound on velocity which singles out space-time.…”

“…In [8] we derived classical velocity from our model. It is simply the quotient between some distance (function of eigenvalues of the space observable) and the time it takes to register a particle at that distance.…”

“…In [7,8] we present a model of quantum measurement which bases on the notions of decoherence and collapse. Given an apparatus or register A, a system S and the environment E at temperature T , the measurement process M can be thought of as being represented by the following sequence:…”
