Strain engineering of Andreev spin qubits in Germanium
Vittorio Coppini, Patrick Del Vecchio, Antonio L. R. Manesco +4
Planar germanium heterostructures are promising hosts for hybrid quantum devices due to their compatibility with superconductors, low material disorder, and relaxed fabrication con…

Kramers-protected hardware-efficient error correction with Andreev spin qubits
Haoran Lu, Isidora Araya Day, Anton R. Akhmerov +2
We propose an architecture for bit-flip error correction of Andreev spins that is protected by Kramers' degeneracy. Specifically, we show that a coupling network of linear inductor…

Nonlinearity of transparent SNS weak links decreases sharply with length
Valla Fatemi, Pavel D. Kurilovich, Anton R. Akhmerov +1
Superconductor-normal material-superconductor (SNS) junctions are being integrated into microwave circuits for fundamental and applied research goals. The short junction limit is a…
