Hi there,

Ok, so if you know the interactions, etc., you can calculate from time0 the probabilities for certain results at say time8.

But say, however, we perform a measurement before time8. Will the original predictions for time8 still hold if a measurement is performed prior to that time? Or will it be different - in that case, what information do you need from the measurement, to plug into the unitary operator (which will include interactions, etc.) to find the new probabilities at time8?

The wave equation can be set up to be as complicated or simple as you like. It is possible to include variation of the equation over time, or make the simplifying assumption that nothing varies over time. It is up to you.
