Theory of Measurement in Quantum Mechanics

Measurement in quantum mechanics FAQ

This is a FAQ on physical and metaphysical approaches to the measurement problem in QM. Please help make it more complete. SeèWhat is needed' for details. The existing sci.physics FAQ does a good job of dealing with technical questions in most areas of physics. However it has no material on interpretations of QM which are among the most frequently discussed topics in sci.physics. Perhaps in par...

The Measurement Problem in Quantum Mechanics Revisited

Characterizing mixing and measurement in quantum mechanics

What fundamental constraints characterize the relationship between a mixture r5( ipir i of quantum states, the states r i being mixed, and the probabilities pi? What fundamental constraints characterize the relationship between prior and posterior states in a quantum measurement? In this paper we show that there are many surprisingly strong constraints on these mixing and measurement processes ...

Measurement and Classical Regime in Quantum Mechanics

In this article, I shall focus on two of the main problems raising interpretational issues in quantum mechanics, namely the notorious measurement problem (discussed together with the theory of measurement in section 4) and the equally important but not quite as widely discussed problem of the classical regime (discussed together with decoherence in section 3). The two problems are distinct, but...
