Prof. Ilegems received an honorary doctorate from the University of Toulouse (1998) and the Heinrich Welker Award from the Compound Semiconductor Symposium (2006) for his contributions to III-V semiconductor materials and device research.
The research activities of the Semiconductor Device Physics Laboratory centred on the physics and technology of semiconductor devices. The main subjects of interest included quantum photonics (semiconductor microcavities, light emitting diodes, lasers and detectors), wide bandgap semiconductor nitrides, physics of nano and low-dimensional structures, high electron mobility transistors, crystal growth and materials technology. The research programs were carried out in close collaboration with numerous academic and industrial groups in Switzerland and abroad, in particular within the framework of programs of the European Community.
Earlier research topics pursued at Bell Laboratories and at EPFL include Molecular Beam Epitaxy and doping of GaAs and AlGaAs thin films with applications to heterostructure lasers, detectors, and Bragg mirrors, hydride vapor phase epitaxy and physical characterization of GaN on sapphire, liquid-solid phase diagrams of ternary III-V compound systems, and silicon-based non-volatile memory cells.

Pasquale Scarlino
I obtained my master's degree in Physics at the University of Salento, Lecce (Italy) in February 2011. During 2006-2011, I have also been a student of Scuola Superiore ISUFI (SSI). SSI is one of six schools of excellence established in Italy to develop the intellectual capital in technological and social sciences. I conducted an external Master thesis project during an 8 months internship in the Quantum Transport Group at TU Delft, under the supervision of Prof. L.M.K. Vandersypen. There, I implemented the Quantum Point Contact Radio-Frequency Reflectometry technique, which allows increasing the single-shot electron spin readout bandwidth and is currently routinely used in the group.I obtained my Ph.D. degree in February 2016, in the Spin Qubits group of Prof. L.M.K. Vandersypen at the Kavli Institute of Nanoscience-Qutech (TU Delft). During my Ph.D. I have been leading the Si/SiGe spin qubits project, collaborating with the M. Eriksson Group at Wisconsin University. In parallel, I have been working on other different projects, in particular with GaAs depletion quantum dots, high impedance superconducting resonators, and surface acoustic wave resonators. I have been working as a Postdoc fellow in the group of Prof. A. Wallraff (Quantum Device Lab) at ETH Zurich. My main project, in collaboration with the group of Prof. K. Ensslin and Prof. T. Ihn, consisted in integrating semiconductor and superconductor technologies. Realizing a well-controlled interface between the semiconductor and superconductor-based quantum information technologies may allow harnessing the best of both device architectures, for example by providing an interface between strongly coupled charge state and high coherence spin states. Furthermore, it enables the possibility to explore light/matter hybridization in a class of solid-state systems and regimes that are new in the context of quantum optics.From June 2019 till September 2020, I have been a Senior Researcher at Microsoft Station Q Copenhagen and at the Center for Quantum Devices in Copenhagen, focusing on developing semiconductor-superconducting hybrid hardware for topologically protected quantum computation.Since October 2020, I am a tenure track Assistant Professor of Physics in the School of Basic Sciences at the EPFL where I founded the Hybrid Quantum Circuit (HQC) laboratory.

Benoît Marie Joseph Deveaud
Benoit Deveaud is now Research Director at Ecole Polytechnique in Palaiseau (France)
Benoît Deveaud was born in France in 1952. In 1971, he enters Ecole Polytechnique in Paris where he specializes in physics. In 1974, he joins the National Center for research in Telecommunications (CNET).
He undertakes at the same time studies on the main impurity centers in III-V semiconductors, and continues his studies in physics by preparing a diploma in solid state physics in Rennes. In 1984, he defends his PhD thesis at the University of Grenoble, under the supervision of Gérard Martinez. Meanwhile, his team gets interested in semiconductor microstructures and launches studies on the structural and optical properties of superlattices based on gallium arsenide. These studies highlight for example vertical transport in superlattices as well as the quantification of excitonic energies in a quantum well.
In 1986 he joins the team of Daniel Chemla in Bell Laboratories (Holmdel, USA) and takes part in the development of the first luminescence set-up having a temporal resolution better than 1 picosecond. He studies then ultrafast processes in quantum wells.
Returning to France in 1988, at CNET, he coaches a laboratory of high-speed studies, interested in the optical and electronic properties of semiconductor materials.
Appointed professor in Physics at EPFL in October 1993, his research team studies the physics of ultrafast processes in semiconductor micro and nanostructures and in devices that use them. He has been the Director the Institute of Micro and Optoelectronics since 1998, then of the Institute of Quantum Photonic and Electronics from 2003 to 2008.
His team takes an active part in the "Quantum Photonics" National Center of Competence in Research, of which he was the Deputy Director from 2001 to 2005 then the Director from July 2005 till the end of the NCCR in 2013
From 2008 till 2014 he has been Dean for Research at EPFL and president of the research commission.
Starting in 2014, he has been head of Physics, till his departure from EPFL in 2017.
He has been a divisional editor of Physical Review Letters from 2001 to 2007.
