General Questions Related to Quantum Measurement

[QUOTE="bhobba, post: 5760223, member: 366323"] The formalism alone these days can be used to determine when a measurement has occurred - its just after decoherence. It doesn't resolve any interpretational issues - just clarifies the idea of what a measurement is. For simplicity you can say the mixed state that occurs after decoherence is a proper mixed state, without detailing exactly what it means or how it becomes one as opposed to an improper mixed state. There is no way to observationally tell the difference which is why you can neither disprove or prove it. If you do that - its called the ignorance ensemble interpretation - then you have an interpretation and most QM issues are resolved. But that is an interpretive assumption. BTW its exactly the same as the ensemble interpretation you can look up except its applied to just after decoherence. Thanks Bill [/QUOTE]
