Abstract

A bomb explodes when anything interacts with it: Can it be found without exploding it? Can we find that the bomb is not present in a particular place without any probe being there? Which tasks can be achieved without particles in the transmission channel: transmission of a classical message, teleportation of a quantum state, establishing a secret key? I will review the claims that these tasks can be done and will argue that only some of them are true.
