Dephasing due to quasiparticle tunneling in fluxonium qubits: a phenomenological approach

Autor: Samuele Spilla, Fabian Hassler, Anna Napoli, Janine Splettstoesser

Publikováno v: New Journal of Physics, Vol 17, Iss 6, p 065012 (2015)

The fluxonium qubit has arisen as one of the most promising candidate devices for implementing quantum information in superconducting devices, since it is both insensitive to charge noise (like flux qubits) and insensitive to flux noise (like charge

Giant thermoelectric effects in a proximity-coupled superconductor–ferromagnet device

Autor: P Machon, M Eschrig, W Belzig

Publikováno v: New Journal of Physics, Vol 16, Iss 7, p 073002 (2014)

The usually negligibly small thermoelectric effects in superconducting heterostructures can be boosted dramatically due to the simultaneous effect of spin splitting and spin filtering. Building on an idea of our earlier work (Machon et al 2013 Phys.

Measurement and dephasing of a flux qubit due to heat currents

Autor: Samuele Spilla, Fabian Hassler, Janine Splettstoesser

Publikováno v: New Journal of Physics, Vol 16, Iss 4, p 045020 (2014)

We study a flux qubit made of a superconducting loop interrupted by three Josephson junctions, which is subject to a temperature gradient. We show that the heat current induced by the temperature gradient, being sensitive to the superconducting phase

We investigate theoretically the non-local conductance through a superconducting wire in tunnel contact with normal and ferromagnetic leads. In the presence of an in-plane magnetic field, the superconducting density of states is spin-split, and the c
