Abstract
Here we present a method of performing quantum state transfer in a chain of superconducting quantum bits. Our protocol is based on the engineerability of the energy levels of superconducting quantum systems. This, together with the tunability of the Josephson energy through an external flux bias allows for on-demand state transfer through a chain of qubits using a straight-forward current ramp on a common flux bias. Numerical simulations of the master equation using realistic parameters for capacitive nearest neighbor coupling, energy relaxation and dephasing shows that fast, high-fidelity state transfer should be feasible using this method.Citation
