Decoherence rates in complex Josephson qubit circuits
Decoherence rates in complex Josephson qubit circuits
A complete analysis of the decoherence properties of a Josephson junction qubit is presented. The qubit is of the flux type and consists of two large loops forming a gradiometer, one small loop, and three Josephson junctions. We develop a complete, quantitative description of the inductances and capacitances of the …
