Are Interaction-free Measurements Interaction Free?
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 interactionfree measurements can be called as “seeing in the dark”. Since then several experiments have been successfully performed and various modifications were suggested...
متن کاملInteraction-Free Measurements
1 The Penrose bomb testing problem I am greatly indebted to Roger Penrose. I have learned very much from his papers, from his exciting books, and from our (too short) conversations. I am most grateful to Roger for developing the idea of Avshalom Elitzur and myself on interaction-free measurements (IFM). The version of IFM Penrose described in his book (1994) is conceptually different from our o...
متن کاملQuantum Mechanical Interaction - Free Measurements
A novel manifestation of nonlocality of quantum mechanics is presented. It is shown that it is possible to ascertain the existence of an object in a given region of space without interacting with it. The method might have practical applications for delicate quantum experiments.
متن کاملThe Meaning of the Interaction-Free Measurements
Interaction-free measurements introduced by Elitzur and Vaidman [Found. Phys. 23, 987 (1993)] allow finding infinitely fragile objects without destroying them. Many experiments have been successfully performed showing that indeed, the original scheme and its modifications lead to reduction of the disturbance of the observed systems. However, there is a controversy about the validity of the term...
متن کاملThe Elitzur-vaidman Interaction-free Measurements
The interaction-free measurements proposed by Elitzur and Vaidman [1] (EV IFM) is a quantum mechanical method to find an object that interacts with other systems solely via its explosion without exploding it. In this method, an object can be found without " touching it " , i.e. without any particle being at its vicinity. The basic idea of the method is as follows. A quantum test particle is bei...
