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…
The Berezinskii-Kosterlitz-Thouless Transition and Anomalous Metallic Phase in a Hybrid Josephson Junction Array
C. G. L. Bøttcher, F. Nichele, J. Shabani +2
We investigate the Berezinskii-Kosterlitz-Thouless (BKT) transition in a semiconductor-superconductor two-dimensional Josephson junction array. Tuned by an electrostatic top gate,…
Parametric longitudinal coupling between a high-impedance superconducting resonator and a semiconductor quantum dot singlet-triplet spin qubit
C. G. L. Bøttcher, S. P. Harvey, S. Fallahi +5
Long-distance two-qubit coupling, mediated by a superconducting resonator, is a leading paradigm for performing entangling operations in a quantum computer based on spins in semico…
Readout Of Singlet-Triplet Qubits At Large Magnetic Field Gradients
Lucas A. Orona, John M. Nichol, Shannon P. Harvey +5
Visibility of singlet-triplet qubit readout is reduced to almost zero in large magnetic field gradients due to relaxation processes. Here we present a new readout technique that is…
Superconducting, Insulating, and Anomalous Metallic Regimes in a Gated Two-Dimensional Semiconductor-Superconductor Array
C. G. L. Bøttcher, F. Nichele, M. Kjaergaard +4
The superconductor-insulator transition in two dimensions has been widely investigated as a paradigmatic quantum phase transition. The topic remains controversial, however, because…
