Optical Communication with Invisible Photons Chapter uri icon


  • It has always been a self-evident and obvious feature of any kind of communication that there should be an exchange of objects like photons or electrons between the sender and the receiver to convey any information. In this chapter a protocol is presented in which information is transmitted between a sender and receiver with no particles in the transmission channel. The basic building block of this counterfactual communication protocol, the MachZehnder interferometer, is discussed. The concept of interaction-free measurement is also introduced.
