Working Group 3
Quantum coherence phenomena such as entanglement lie at the heart of quantum science and technology and they represent the basis, for instance, for quantum information & computation, quantum metrology and energy transfer in light-harvesting complexes.
The goal of the WG3 is to explore manifestations of quantum coherence at the nanoscale. Due to its fundamental and very general nature, this topic is transverse to the topics of the other work groups, and presents substantial overlaps with them (e.g. colour centres, plasmons, quantum dots, nanoresonators and so on are tools investigated in other work groups too).
