Silent Phase Qubit Based on d-Wave Josephson Junctions
M. H. S. Amin, A. Yu. Smirnov, A. M. Zagoskin +4
We report on design and fabrication of a new type of flux qubit that capitalizes on intrinsic properties of submicron YBCO grain boundary junctions. The operating point is protecte…

Quasiparticle Decoherence in d-wave Superconducting Qubits
M. H. S. Amin, A. Yu. Smirnov
It is usually argued that the presence of gapless quasiparticle excitations at the nodes of the d-wave superconducting gap should strongly decohere the quantum states of a d-wave q…
