Optimized heat transfer at exceptional points in quantum circuits
Matti Partanen, Jan Goetz, Kuan Yen Tan +12
Superconducting quantum circuits are potential candidates to realize a large-scale quantum computer. The envisioned large density of integrated components, however, requires a prop…
Qubit Measurement by Multichannel Driving
Joni Ikonen, Jan Goetz, Jesper Ilves +10
We theoretically propose and experimentally implement a method of measuring a qubit by driving it close to the frequency of a dispersively coupled bosonic mode. The separation of t…
Multiplexed readout of kinetic inductance bolometer arrays
Hannu Sipola, Juho Luomahaara, Andrey Timofeev +4
Kinetic inductance bolometer (KIB) technology is a candidate for passive sub-millimeter wave and terahertz imaging systems. Its benefits include scalability into large 2D arrays an…
Observation of a broadband Lamb shift in an engineered quantum system
Matti Silveri, Shumpei Masuda, Vasilii Sevriuk +9
The shift of energy levels owing to broadband electromagnetic vacuum fluctuations, the Lamb shift, has been pivotal in the development of quantum electrodynamics and in understandi…
Nanobolometer with Ultralow Noise Equivalent Power
R. Kokkoniemi, J. Govenius, V. Vesterinen +10
Since the introduction of bolometers more than a century ago, they have been applied in a broad spectrum of contexts ranging from security and the construction industry to particle…
Flux-driven Josephson parametric amplifier for sub-GHz frequencies fabricated with side-wall passivated spacer junction technology
Slawomir Simbierowicz, Visa Vesterinen, Leif Grönberg +3
We present experimental results on a Josephson parametric amplifier tailored for readout of ultra-sensitive thermal microwave detectors. In particular, we discuss the impact of fab…
