Decoherence of Phase Qubit using High-Tc Superconductor
arXiv:cond-mat/0504274 · doi:10.1016/j.physe.2005.06.051
Abstract
We discuss how to make use of high-Tc d-wave Josephson junctions in the construction of a phase qubit. We especially focus on the effect of the quasiparticle dissipation and the zero energy bound state on the macroscopic quantum tunneling which corresponds to the final measurement process of the d-wave phase qubit.
