Generation of entangled states of two distant cavity modes via Josephson junction based devices

Risultato della ricerca: Article

Abstract

We present a simple scheme for the preparation of entangled states of the e.m. modes oftwo spatially separated microwave cavities exploiting their interaction with two superconductingSQUID rings embedded within them. The scheme requires that the twoSQUID qubits are initially prepared in an entangled state and the possibility of controllingboth the coupling strengths and the interaction times. We also briefly discuss theimportance of such a theoretical scheme in view of possible applications in the contextof quantum computing and its experimental feasibility.
