The emergence of the classical world from quantum theory, and especially of a consensus among different observers, is a long-standing problem for the foundations of quantum theory. Using recent advances in multipartite quantum information theory, we shed light on these problems. Besides their interest for fundamental physics, they are related to quantum sensing and metrology using a quantum-network of stations, a situation of interest for the potential use of quantum-based measurement probes for exploring space and the Universe.

The objective of this activity was to propose a general infrastructure of an end-to-end simulator (E2ES) for space science missions, namely an E2ES requirements baseline, reference architecture and an associated library of software models (building blocks, BB) to promote reuse, standardisation and reduction of engineering costs by defining a products/science validation process throughout the lifecycle based on an E2ES.

Previous research has already demonstrated that graphene field effect transistors can be operated at incredibly high bandwidths, demonstrating 25+GHz with a theoretical limit of up to 500GHz for visible photodetection. Ultrafast photodetection has also been demonstrated on the 10s of femtosecond scale via the photothermoelectric effect for visible photodetection.
