Project: Ressources électroniques quantiques
| Acronym | ElQuRes |
| Duration | 01/05/2024 - 30/04/2027 |
| Project Topic | The ambition of ELQURES is to contribute to the second quantum revolution in electronics by using coherent ballistic electrons and quantum states of electromagnetic resonators as resources for quantum-limited measurements and information processing. Established quantum technology platforms exploit the ability to generate, control and measure individual quantum excitations in a particular physical substrate which can vary from electromagnetic modes to atomic levels to spins of confined electrons. ELQURES brings the spotlight to a novel type of quantum resource and explores coherent propagating electrons as a source for non-classical states that can be efficiently manipulated electrically and integrated with other on-chip platforms. The scientific objectives of ELQURES are: (i) develop a unified framework for quantum tomography of electrical currents integrating different energy regimes and measurement principles; (ii) establish foundations for the control of coherent light-matter coupling between single to few electrons and electromagnetic fields with the aim of generating non-classical states of those field; (iii) demonstrate sources of coherent picosecond-scale wave-packets that enable all-electrical metrology of electrical signals with quantum resolution. The project brings together pioneers of solid-state electron quantum optics (ENS Paris and ENS Lyon) and leaders of single-electron technologies for fundamental electrical metrology (PTB, University of Latvia) that are uniquely positioned to unlock the potential of electronic coherence in the non-linear and the hot-electron regimes. The broader goal of ElQuRes is to advance the science of electron quantum optics to novel regimes and catalyze the emergence of single-electron quantum technologies with Europe in the leading role. |
