End-to-end correlated subgap states in hybrid nanowires
G. L. R. Anselmetti, E. A. Martinez, G. C. Ménard +9
End-to-end correlated bound states are investigated in superconductor-semiconductor hybrid nanowires at zero magnetic field. Peaks in subgap conductance are independently identifie…
Time-domain characterization and correction of on-chip distortion of control pulses in a quantum processor
M. A. Rol, L. Ciorciaro, F. K. Malinowski +7
We introduce Cryoscope, a method for sampling on-chip baseband pulses used to dynamically control qubit frequency in a quantum processor. We specifically use Cryoscope to measure t…
Conductance-matrix symmetries of a three-terminal hybrid device
G. C. Ménard, G. L. R. Anselmetti, E. A. Martinez +10
We present conductance-matrix measurements of a three-terminal superconductor-semiconductor hybrid device consisting of two normal leads and one superconducting lead. Using a symme…
A fast, low-leakage, high-fidelity two-qubit gate for a programmable superconducting quantum computer
M. A. Rol, F. Battistel, F. K. Malinowski +8
A common approach to realize conditional-phase (CZ) gates in transmon qubits relies on flux control of the qubit frequency to make computational states interact with non-computatio…
Suppressing quasiparticle poisoning with a voltage-controlled filter
Gerbold C. Ménard, Filip K. Malinowski, Denise Puglia +5
We study single-electron charging events in an Al/InAs nanowire hybrid system with deliberately introduced gapless regions. The occupancy of a Coulomb island is detected using a ne…
Radio-frequency methods for Majorana-based quantum devices: fast charge sensing and phase diagram mapping
Davydas Razmadze, Deividas Sabonis, Filip K. Malinowski +9
Radio-frequency (RF) reflectometry is implemented in hybrid semiconductor-superconductor nanowire systems designed to probe Majorana zero modes. Two approaches are presented. In th…
