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…
Injection locking and parametric locking in a superconducting circuit
Danijela Marković, Jean-Damien Pillet, Emmanuel Flurin +2
When a signal is injected in a parametric oscillator close enough to its resonance, the oscillator frequency and phase get locked to those of the injected signal. Here, we demonstr…
