Andreev spin qubit protected by Franck-Condon blockade
P. D. Kurilovich, T. Vakhtel, T. Connolly +2
Andreev levels localized in a weak link between two superconductors can trap a superconducting quasiparticle. If there is a spin-orbit coupling in the link, the spin of the quasipa…

Using bi-fluxon tunneling to protect the Fluxonium qubit
Waël Ardati, Sébastien Léger, Shelender Kumar +8
Encoding quantum information in quantum states with disjoint wave-function support and noise insensitive energies is the key behind the idea of qubit protection. While fully protec…

Tunneling of fluxons via a Josephson resonant level
T. Vakhtel, P. D. Kurilovich, M. Pita-Vidal +3
Fluxons in a superconducting loop can be coherently coupled by quantum phase slips occurring at a weak link such as a Josephson junction. If Cooper pair tunneling at the junction o…
