Institut Néel's superconducting circuit lab in Grenoble
Our interns, PhDs, Postdocs, and staff members work on a wide range of topics in complementary research directions.
Mesoscopic physics and superconducting qubits
Olivier Buisson is a senior CNRS researcher (Directeur de Recherche) and the director of the LANEF consortium in Grenoble. His main research areas concern mesoscopic physics and superconducting qubits. Coordinator of The ANR Projet Octaves (2021-2025). In 1999, he initiated quantum dynamics in superconducting qubits and proposed Quantum ElectroDynamics experiments using superconducting qubits. He experimentally studies a large variety of superconducting qubits since then. In 1990, he was contracted to the CRTBT-CNRS lab in Grenoble and studied plasma modes in thin superconducting films. Post-doctoral research in Rio de Janeiro with Prof. Paulo Costa Ribiero and Mauro Doria on biophysics and modelization of anisotropic superconductors. PhD (1990) at the Joseph Fourier University (Grenoble) on superconducting mesoscopic disks and superconducting networks under the supervision of Bernard Pannetier.

Acoustics and nanomechanics with superconducting microwave circuits
Jeremie Viennot is a CNRS researcher since 2020. His research currently focuses on the development of quantum acoustics and nanomechanical devices, coupled to superconducting circuits via the piezoelectric effect. Coordinator of ANR project Q-MagMech (2020-2025). Marie Sklodowska-Curie fellow (2019-2020). Postdoctoral research in the group of Konrad Lehnert at JILA, Colorado University Boulder (USA), working on quantum acoustics and microwave optomechanics with superconducting qubits. PhD (2015) under the supervision of Takis Kontos at ENS Paris, focusing on hybrid circuit quantum electrodynamics with spins in carbon nanotube quantum dots.
Erika Borsje-Hekking has been a Project Manager at the Néel Institute since October 2017. Currently, she is taking care of the PEPR RobustSuperQ of the French Quantum Initiative, coordinated by Nicolas Roch and Denis Vion (Cea-Saclay).
