Strongly anisotropic non-Kramers electron spin as a quantum coherence probe of angular fluctuations
Achuthan Manoj Kumar, Remy Dassonneville, Guillaume Gerbaud +5
Strongly anisotropic non-Kramers rare-earth ions combine giant longitudinal g-factors with a vanishing transverse component imposed by time-reversal symmetry, a combination that ma…
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…
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…
Understanding the saturation power of Josephson Parametric Amplifiers made from SQUIDs arrays
Luca Planat, Remy Dassonneville, Javier Puertas Martinez +7
We report on the implementation and detailed modelling of a Josephson Parametric Amplifier (JPA) made from an array of eighty Superconducting QUantum Interference Devices (SQUIDs),…
A tunable Josephson platform to explore many-body quantum optics in circuit-QED
Javier Puertas Martinez, Sebastien Leger, Nicolas Gheeraert +10
Coupling an isolated emitter to a single mode of the electromagnetic field is now routinely achieved and well understood. Current efforts aim to explore the coherent dynamics of em…
