Granular Aluminum Parametric Amplifier for Low-Noise Measurements in Tesla Fields
Nicolas Zapata, Ivan Takmakov, Simon Günzler +8
Josephson junction parametric amplifiers have become essential tools for microwave quantum circuit readout with minimal added noise. Even after improving at an impressive rate in t…

Pure kinetic inductance coupling for cQED with flux qubits
Simon Geisert, Soeren Ihssen, Patrick Winkel +11
We demonstrate a qubit-readout architecture where the dispersive coupling is entirely mediated by a kinetic inductance. This allows us to engineer the dispersive shift of the reado…
