Entanglement Enhanced Information Transfer through Strongly Correlated Systems and its Application to Optical Lattices

Abstract

We show that the inherent entanglement of the ground state of strongly correlated systems can be exploited for both classical and quantum communications. Our strategy is based on a single qubit rotation which encodes information in the entangled nature of the ground state. In classical communication, our mechanism conveys more than one bit of information in each shot, just as dense coding does, without demanding long range entanglement. In our scheme for quantum communication, which may more appropriately be considered as a remote state preparation, the quality is higher than the highly studied attaching scenarios. Moreover, we propose to implement this new way of communication in optical lattices where all the requirements of our proposal have already been achieved.
