Benchmarking Dark Matter Search using a Parity-Check Protocol with Machine-Learning Optimized Pulses
Yu-Han Chang, Ilya Moskalenko, Marko KuzmanoviÄ +7
We report on an improved microwave detection protocol for dark matter candidates such as the axion and the dark photon. We employ a superconducting transmon qubit dispersively coup…
Millimeter Wave Readout of a Superconducting Qubit
Akash V. Dixit, Zachary L. Parrott, Dennis Chunikhin +3
Millimeter waves are emerging as an enabling technology for connecting and enhancing different quantum platforms such as Rydberg atoms, optomechanics, and superconducting qubits. I…
Interface-sensitive microwave loss in superconducting tantalum films sputtered on c-plane sapphire
Anthony P. McFadden, Jinsu Oh, Lin Zhou +5
Quantum coherence in superconducting circuits has increased steadily over the last decades as a result of a growing understanding of the various loss mechanisms. Recently, tantalum…
End-to-end workflow for machine learning-based qubit readout with QICK and hls4ml
Giuseppe Di Guglielmo, Botao Du, Javier Campos +10
We present an end-to-end workflow for superconducting qubit readout that embeds co-designed Neural Networks (NNs) into the Quantum Instrumentation Control Kit (QICK). Capitalizing…
