Inductively-protected Andreev (IPA) spin qubit
J. L. del Olmo N., F. J. Matute-Cañadas, A. Levy Yeyati +2
The spin of a quasiparticle trapped in a quantum dot Josephson junction forms the basis of an Andreev spin qubit (ASQ): a semiconductor-superconductor device where the interplay be…

Ultrastrong Coupling and Coherent Dynamics in a Gate-Tunable Transmon Qubit
I. Casal Iglesias, F. J. Matute-Cañadas, G. O. Steffensen +10
Ultrastrong light-matter coupling (USC) gives access to exotic quantum phenomena and promises faster quantum gates, yet coherent time-domain control in this regime remains largely…

Single-shot parity readout of a minimal Kitaev chain
Nick van Loo, Francesco Zatelli, Gorm O. Steffensen +12
Protecting qubits from noise is essential for building reliable quantum computers. Topological qubits offer a route to this goal by encoding quantum information non-locally, using…
