Our research is devoted to the study and development of quantum functionalities in semiconductor systems using the nanofabrication techniques of opto-electronics. We develop high performances integrated sources of quantum light, non-linear devices operating at the single photon level, spin-based quantum memories and optomechanical platforms for quantum information processing.

The group conducts theoretical research on correlated quantum systems. Our main efforts focus on the physics of systems that constitute promising plateforms for concrete realization of quantum technologies. Together with other systems in condensed matter and quantum optics, ultracold atoms have already produced milestone results, which turn quantum technologies from dream to reality.

Electronic energy transfer (EET) is a ubiquitous photophysical process that plays a crucial role in the light-harvesting capabilities of natural antenna complexes, and could also hold important implications in artificial systems. Emerging experimental breakthroughs indicate that the dynamics of light harvesting is not fully described by a classical random-walk picture, but also quantum coherent transfer takes place.

The Commission High Level Steering Committee (http://qurope.eu/db/news/expert-group-quantum-technology-flagship) has released a summary of the results obtained during its first meeting (Brussels, Tuesday 20 Spetember 2016).

Our research group explores the physics of information in quantum integrated circuits, which we design, realize and measure. These objects can be viewed as quantum machines processing information. In contrast with ordinary circuits, in which quantum mechanics enters only at the level of individual electrons, the degrees of freedom of these machines at the signal level behave according to the laws of quantum mechanics.

MULTI replaces the familiar sequential model of computation that uses Boolean variables and combinational gates by logic operations that are executed in parallel on devices that have a built-in many state memory and whose inputs and outputs are multivalued. MULTI seeks to design, simulate and experimentally implement proof of principle devices on the atomic and molecular scale.

The TCP group research activities focus on the theory and modeling of the dynamics of molecular systems subject to external perturbations, with applications to
