Paper Abstract

The dc SQUID qubit can be viewed as a single current biased Josephson junction attached to an inductive isolation network. Excellent broadband isolation is possible and is adjustable in situ. The isolation network increases the effective shunt resistance due to the lead impedance allowing for long energy dissipation times T1. We present data on Rabi oscillations, and macroscopic quantum tunneling as isolation from the bias leads is varied.
