Impulsive quantum measurements: Restricted path integral vs. von Neumann collapse

  • Published:
Il Nuovo Cimento B (1971-1996)

Summary

The relation between the restricted path integral approach to quantum measurement theory and the commonly accepted von Neumann wave function collapse postulate is presented. It is argued that in the limit of impulsive measurements the two approaches lead to the same predictions. The example of repeated impulsive quantum measurements of position performed on a harmonic oscillator is discussed in detail and the quantum non-demolition strategies are recovered in both the approaches.
