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 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...
متن کاملOn the realization of interaction-free measurements
A pMsiblc realistic implemenwion of a method for inkmtion-free measurements. due to Elitzur and Vaidman. is proposed and discussed. It is argwd that the effed can be obse~ed in an optical laboratory. The interaction-free measurements of Elitzur and Vaidman [l] is a proposal to consider a well known device and ask a question which is, in a sense, opposite to what is usually asked. The suggested ...
