State preparation of a fluxonium qubit with feedback from a custom FPGA-based platform
Richard Gebauer, Nick Karcher, Daria Gusenkova +12
We developed a versatile integrated control and readout instrument for experiments with superconducting quantum bits (qubits), based on a field-programmable gate array (FPGA) platf…
Observation of quantum many-body effects due to zero point fluctuations in superconducting circuits
Sebastien Leger, Javier Puertas-Martinez, Karthik Bharadwaj +11
Electromagnetic fields possess zero point fluctuations (ZPF) which lead to observable effects such as the Lamb shift and the Casimir effect. In the traditional quantum optics domai…
Non-degenerate parametric amplifiers based on dispersion engineered Josephson junction arrays
Patrick Winkel, Ivan Takmakov, Dennis Rieger +12
Determining the state of a qubit on a timescale much shorter than its relaxation time is an essential requirement for quantum information processing. With the aid of a new type of…
Fabrication and characterization of aluminum SQUID transmission lines
Luca Planat, Ekaterina Al-Tavil, Javier Puertas Martinez +10
We report on the fabrication and characterization of 50 Ohms, flux-tunable, low-loss, SQUID-based transmission lines. The fabrication process relies on the deposition of a thin die…
A photonic crystal Josephson traveling wave parametric amplifier
Luca Planat, Arpit Ranadive, Remy Dassonneville +7
An amplifier combining noise performances as close as possible to the quantum limit with large bandwidth and high saturation power is highly desirable for many solid state quantum…
