[QUOTE="WernerQH, post: 6799877, member: 686891"] I believe you have this backwards. What you are talking about is a theoretian's idealized measurement that has little to do with real experiments. Applied to a harmonic oscillator, a position measurement would imply adding an infinite amount of kinetic energy, if the imagined collapsed state really were an eigenstate of the position operator. Contrariwise, there is little reason to doubt that the correlation function ## \langle x(t)x(0) \rangle ## computed for an unperturbed oscillator is a useful first approximation to measurement results. And of course this first approximation can be improved by including perturbing effects (as done by Schwinger). [/QUOTE]
