In the very first pages of "Quantum Mechanics" by Landau & Lifchitz, the measurement process is described as an interaction between a quantum system and a "classical" system.(adsbygoogle = window.adsbygoogle || []).push({});

I like this interpretation since any further evolution of the quantum system is anyway entangled with the "classical" system.

I think it is quite plausible that this evolution as described by the SE, would agree to the evolution as postulated from the famous wavepacket "reduction axiom". (maybe by assuming further that "classical" means a very dense energy spectrum)

Have some of you seen some proofs or some models that details/discuss this point of view?

Thanks, Michel
