Realizing a SWAP gate and generating cluster states in a controllable superconducting coupling system
Feng‐Yang Zhang, Pei Pei, Zhen Wang, He‐Shan Song · Physica Scripta · 2010
We propose a new controllable protocol for information transmission which is based on coupling superconducting charge qubits to a single-mode quantum transmission line. We show how to physically implement high-fidelity information transmission by controlling the external magnetic flux in this system. By choosing appropriate parameters, the cluster states can be generated. Finally, we investigate the feasibility of this protocol with present-day technology.
