Quasiparticle Dissipation in d-wave Superconductor Phase Qubit
Recent phase sensitive experiments on high Tc superconductors, e.g.,
YBa_2Cu_3O_7 single crystals, have established the d-wave nature of the cuprate
materials. Here we discuss how to make use of d-wave Josephson junctions in the
construction of a phase qubit. We especially focus on the effect of
quasiparticle dissipation on the macroscopic quantum tunneling which
corresponds to the measurement process for the d-wave phase qubit.Comment: 3 pages, 1 figure, The Seventh International Conference on Quantum
