We introduce a three-junction superconducting quantum interference device SQUID that can be used as an optimal tunable element in Josephson quantum computing applications. This device can replace the simple dc SQUID generally used as a tunable element in this kind of applications, with a series of advantages concerning the coherence time and the tolerance to small errors. We study the device both theoretically and experimentally at 4.2 K, obtaining a good agreement between the results. ©

Abstract

We introduce a three-junction superconducting quantum interference device SQUID that can be used as an optimal tunable element in Josephson quantum computing applications. This device can replace the simple dc SQUID generally used as a tunable element in this kind of applications, with a series of advantages concerning the coherence time and the tolerance to small errors. We study the device both theoretically and experimentally at 4.2 K, obtaining a good agreement between the results. ©
