Information propagation in a quantum system. Examples of open spin-1/2 chains

Abstract

If the information is encoded into the state of the subsystem SS of a quantum system initially (at t=0t=0), then it becomes distributed over the whole quantum system at t>0t>0 due to the quantum interactions. Consequently, this information, in general, can be extracted, either completely or partially, from any subsystem of a quantum system. {We suggest a method of extraction of information, which is based on the polarization measurements on the receiver RR}.
