Quasiparticle dissipation in the measurement process of phase qubit using high-T-c superconductors

摘要

We discuss how to make use of high-T-c d-wave Josephson junctions in the construction of a phase qubit. We especially focus oil 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.
