Remote state preparation and measurement of single photon
Arun K. Pati
abstract: Quantum information theory has revolutionized the way in which information is
processed using quantum resources such as entangled states, local operations
and classical communications. Two important protocols in quantum communications
are quantum teleportation and remote state preparation. In quantum
teleportation neither the sender nor the receiver know the identity of a state.
In remote state preparation the sender knows the state which is to be remotely
prepared without ever physically sending the object or the complete classical
description of it. Using one unit of entanglement and one classical bit Alice
can remotely prepare a photon (from special ensemble) of her choice at Bob's
laboratory. In remote state measurement Alice asks Bob to simulate any single
particle measurement statistics on an arbitrary photon. In this talk we will
present these ideas and discuss the latest developments and future open
problems.
