Thus, of course, we favor quantum measurement over classical measurement. Quantum measurement suffers from a problem called decoherence. Many folk are working on a concept of quantum measurement which is non-destructive, i.e., which does not alter stuff which is being measured. If you look at our 24Jul99 section of Flash , you will see nondestructive measurement of a simple quanton's phase has finally been accomplished. It is important to know that quantum decoherence is a measurement problem.
All actual reality is partially decoherent.
It is SQ, or Static Quality. But often we wish to animately measure quantons without causing them to decohere or latch. We are just now learning how to do that. Our animated quantons are semiotics for that dynamic process. End 22-23May2001 aside.
