A low-cost compact muon detector for millikelvin operation
Tengiz Ibrayev, Danish Khan, Alex Herscovics +5
Ionizing radiation produces correlated errors in superconducting qubits, posing some challenges to quantum error correction. In addition, it causes background events in other super…
Local and Non-local Microwave Impedance of a Three-Terminal Hybrid Device
B. Harlech-Jones, S. J. Waddy, J. D. S. Witt +8
We report microwave impedance measurements of a superconductor-semiconductor hybrid nanowire device with three terminals (3T). Our technique makes use of transmission line resonato…
InAs-Al Hybrid Devices Passing the Topological Gap Protocol
Morteza Aghaee, Arun Akkala, Zulfi Alam +124
We present measurements and simulations of semiconductor-superconductor heterostructure devices that are consistent with the observation of topological superconductivity and Majora…
Dispersive Gate Sensing the Quantum Capacitance of a Point Contact
M. C. Jarratt, A. Jouan, A. C. Mahoney +5
The technique of dispersive gate sensing (DGS) uses a single electrode to readout a qubit by detecting the change in quantum capacitance due to single electron tunnelling. Here, we…
An FPGA-based Instrumentation Platform for use at Deep Cryogenic Temperatures
I. D. Conway Lamb, J. I. Colless, J. M. Hornibrook +4
We describe a cryogenic instrumentation platform incorporating commercially-available field-programmable gate arrays (FPGAs) configured to operate well beyond their specified tempe…
