• Anyons on demand (2 years contract- ANR FullyQuantum 2018):

The Nanoelectronics Group currently has an opening for a Post-Doctoral Position on our experiment on Anyonic statistics with Fractional Levitons in the Fractional Quantum Hall Effect regime.

We are looking for an excellent and highly motivated candidate to lead a presently running experiment on the project on abelian and non-abelian statististics using on-demand anyon sources based on levitons in the FQHE regime. Through electronic Hong Ou Mandel interferences, the time control would permit an unprecedented measurement of the quantum statistical angle of e/3 or e/5 anyons or non-abelian anyons.

  • Electron quantum optics in graphene (2 years contract- EMPIR 2018):

Quantum computing is based on the manipulation of quantum bits (qubits) to enhance the efficiency of information processing. In solid-state systems, two approaches have been explored:
1/ static qubits, coupled to quantum buses used for manipulation and information transmission,
2/ flying qubits which are mobile qubits propagating in quantum circuits for further manipulation.
Flying qubits research led to the recent emergence of the field of electron quantum optics, where electrons play the role of photons in quantum optic like experiments. This has recently led to the development of electronic quantum interferometry as well as single electron sources. As of yet, such experiments have only been successfully implemented in semi-conductor heterostructures cooled at extremely low temperatures. Realizing electron quantum optics experiments in graphene, an inexpensive material showing a high degree of quantum coherence even at moderately low temperatures, would be a strong evidence that quantum computing in graphene is within reach.
One of the most elementary building blocks necessary to perform electron quantum optics experiments is the electron beam splitter, which is the electronic analog of a beam splitter for light. However, the usual scheme for electron beam splitters in semi-conductor heterostructures is not available in graphene because of its gapless band structure. I propose a breakthrough in this direction where pn junction plays the role of electron beam splitter.
