Quantum state transfer in arrays of flux qubits

Abstract

In this work, we describe a possible experimental realization of Bose’s idea to use spin chains for short distance quantum communication [S. Bose, Phys. Rev. Lett. 91 207901]. Josephson arrays have been proposed and analyzed as transmission channels for systems of superconducting charge qubits. Here, we consider a chain of persistent current qubits, that is… (More)
