Main achievements in Physics
I have
performed an experimental PhD on superconducting quantum bits (Saclay, France, 1999-2002). This work led to the first
superconducting quantum bit prototype with a lifetime of the order of a
microsecond [Science
296, 886 (2002)]. After
my thesis, I became a theorist of hybrid mesoscopic electronic circuits.
I was a post-doc in Basel, Switzerland (2002-2005), and then Paris (2005-2008),
working on spin dependent transport in
quantum dots as well as superconducting and ferromagnetic proximity
effects in hybrid diffusive structures. Highlights from this period
include the discovery of a spin transistor effect in carbon nanotubes
[Nature Phys. 1, 99 (2005)], a prediction
of positive
current cross-correlations in quantum dot circuits [Phys. Rev.
Lett. 92, 206801 (2004) /
Phys. Rev. B 70, 115315 (2004)], which
was realized experimentally in 2007 in the group of C. Marcus (in Harvard at
that time), and the development of spin-dependent boundary conditions for
quasi-classical superconductivity [Phys. Rev. B 72, 180503(R) (2005) / Phys. Rev. B 80, 184511 (2009)]. Since my
arrival at the Laboratoire Pierre Aigrain
of ENS-Paris, I have mainly focused on the development of Mesoscopic Quantum
Electrodynamics (or Cavity Quantum Electrodynamics with hybrid nanocircuits),
in close collaboration with the experimental "Hybrid
Quantum Circuits" team of Takis Kontos.
The results of this collaboration include the observation of a coherent
spin/photon coupling at the single spin level [Science
349, 6246 (2015)],
photon-emission by a quantum dot/superconductor junction [Phys. Rev. X, 6, 021014 (2016)] and the freezing
of the charge dynamics in a Kondo impurity [Nature 545,
71 (2017)]. More recently, I have started working on the
superconducting proximity effect in Weyl semimetals and the quantum detection
of Dark Matter.
A secondary activity in Archaeomusicology
I also
have a secondary research activity on the history of concussion idiophones from antiquity
to today. I am carrying out this project in parallel
with my research in Physics. Such a wide range of research themes is possible
thanks to the multidisciplinary character of my employer the CNRS. For more
details see here.
