Assistant professor position, Sorbonne Université, SYRTE laboratory, Paris (section 30).

The Systèmes de Référence Temps-Espace (SYRTE) laboratory carries out research in the field of fundamental astronomy, time and frequency metrology and sensor, and history of astronomy. A pioneering institution in their deveopment, it studies different types of cold-atom-based quantum sensors: microwave clocks, optical clocks and inertial sensors (gyrometers, gravimeters, gradiometers, chip-scale interformeters). These sensors have demonstrated a remarkable efficiency for realizing measurement instruments of unprecedented performances, for innovative applications in different disciplinary fields: geophysics, fundamental metrology, tests of fundamental laws of physics, positionning and navigation. In order to overcome sensitivity limits of these sensors, or improve their compactnes to turn them into transportable devices, it is important to utilize ressources offered by quantum mechanics, which have been, so far, little exploited for space-time measurement. These protocols include, as exemples, optimal quantum control, non-demolition measurement and preparation of squeezed states for measurement beyond the standard quantum limit, or even entanglement between different sensors. The SYRTE laboratory wants to hire an Assistant Professor in  quantum physics to work in the specific domain of quantum protocoles applied to cold atoms sensors, in order to improve their limits in terms of sensitivity, and strengthen its position in ahighly competitive domain at the international scale.

Workshop on Standardization of Galileo Timing Receivers (Prague, February 2, 2024, 10:00-13:00 CET)

The primary objective of the workshop is to present the ongoing standardisation activities for timing receivers.

The availability of accurate and secure timing information is crucial for a range of strategic sectors. This is especially the case for critical infrastructures, like telecommunication networks, energy distribution grids, financial markets. All of these will benefit from the future Galileo Timing Service.

In a joint effort, EUSPA and the European Commission will host  a workshop dedicated present the ongoing standardisation activities for timing receivers, aimed at the publication of the first ever Standard in 2024, a key component of the upcoming Galileo Timing Service. The workshop will provide a great opportunity for discussing with Stakeholders on the benefits for Timing and Synchronisation (T&S) applications, and on the user needs of the Timing community.

The workshop will be hybrid, taking place online and at EUSPA HQ.
