Multiplexed readout of Superconductor--Normal-Conductor--Superconductor bolometers
Priyank Singh, András Gunyhó, Heikki Suominen +9
Recently, ultrasensitive calorimeters have been proposed as a resource-efficient solution for multiplexed qubit readout in superconducting large-scale quantum processors. However,…

Low-characteristic-impedance superconducting tadpole resonators in the sub-gigahertz regime
Miika Rasola, Samuel Klaver, Jian Ma +4
We demonstrate a simple and versatile resonator design based on a short strip of a typical coplanar waveguide shorted at one end to the ground and shunted at the other end with a l…

Decay-protected superconducting qubit with fast control enabled by integrated on-chip filters
Aashish Sah, Suman Kundu, Heikki Suominen +2
Achieving fast gates and long coherence times for superconducting qubits presents challenges, typically requiring either a stronger coupling of the drive line or an excessively str…
