Abstract

In 1993, Elitzur and Vaidman introduced the concept of interaction-free measurements, which allowed finding objects without "touching" them. In the proposed method, since the objects were not touched, even by photons, thus, the interaction-free measurements can be called "seeing in the dark." Since then, several experiments have been successfully performed and various modifications were suggested. Recently, however, the validity of the term "interaction-free" has been questioned. The criticism of the name is briefly reviewed and the meaning of the interaction-free measurements is clarified.
