Abstract:
The effect of a position measurement on one component of a two-particle wave packet in a regularized space-momentum entangled
state is analyzed. The wave packet interacts in the physical space with a potential barrier. When a position or momentum measurement
is performed on one particle, a consequent strong modification of the dynamics of the other particle occurs.
