Quantum Photonics, Electronics and Engineering (PHELIQS)
Head : Jean-Michel GERARD - Deputy Head : Jean-Pascal BRISON

The laboratory for Quantum Photonics, Electronics and Engineering (PHELIQS) is a joint research unit of CEA and of the Grenoble Alpes University (UGA). PHELIQS consists of five teams, gathering altogether a permanent staff around 60 (researchers, university professors, technical and administrative staff) and hosts around 35 PhD students and 15 postdoctoral researchers.


PHELIQS is a basic research laboratory whose activities enter mainly into the fields of nanophysics and condensed matter physics, with potential mid or long term application prospects to information and communication technologies. PHELIQS researchers aim at understanding and mastering the original physical effects (in most case of quantum origin) which appear in solid-state systems of low dimensionality (2D, 1D, 0D) and in materials with strong electronic correlations. Their ambition encompasses finding novel solutions to major open problems in photonics and nanoelectronics, including the development of devices for quantum information processing.

The scientific activity of PHELIQS is based on a strong expertise and powerful tools for the controlled synthesis of innovative bulk materials and nanostructures (semiconductor nanowires and quantum dots, monolayers of graphene or other two-dimensional materials), as well as for the nanofabrication of nanostructures and nanodevices within the PTA clean room in Grenoble. PHELIQS also develops for its research programs dedicated high performance instrumentation for physical measurement under extreme conditions (low temperatures down to 10 mK, large magnetic field, high pressure) and for high sensitivity measurements (optical studies at the single photon level, transport studies at the single electron level, scanning tunneling microscopy and spectroscopy, quantum bit measurements). PHELIQS also builds upon its strong theoretical expertise in condensed matter physics (superconductivity, magnetism, strongly correlated electron systems) as well in quantum and mesoscopic physics.
