RT Journal Article T1 Dynamical analysis of seemingly interaction-free measurements A1 Luis Aina, Alfredo A1 Sánchez Soto, Luis Lorenzo AB A full quantum analysis of 100% efficient interaction-free measurements is presented. It is shown that it is possible to describe consistently the phenomenon in terms of an effective interaction between object and apparatus that disturbs measurable quantities of the observed system.
