The University of Amsterdam hosts the Strontium Quantum Gases group of Florian Schreck, who coordinates QuRIOUS. The group uses strontium quantum gases to study quantum many-body physics and for precision measurement. Besides the QuRIOUS project, three projects are pursued: the creation of ultracold RbSr ground-state molecules, a programmable quantum simulator based on individual Sr atoms in optical tweezers and a continuous atom laser. The group also coordinates the AQuRA project, and has previously coordinated MoSaiQC and iqClock.

The University of Birmingham’s Cold Atoms Group is led by Prof. Yeshpal Singh. The Cold Atoms Research Group was set up during 2008 and is part of the Midlands Ultra Cold Atoms Research Centre (MUARC) together with the University of Nottingham. Scientists of the Cold Atoms group in Birmingham are leading the national Quantum Technology Hub for Sensors and Metrology that has the aim of exploiting the exceptional properties of quantum matter to realise real-world applications like ultra-precise atomic clocks and interferometers and ‘gravitational cameras’ which can unveil the underworld – from modern urban infrastructure to the buried secrets of Stonehenge.

The French National Centre for Scientific Research (French: Centre national de la recherche scientifique, CNRS) is France’s largest public research operator, as well as the largest fundamental science agency in Europe employing more than 10,000 tenure researchers in all fields of natural sciences, technology, humanities and social sciences. The research activities of QuRIOUS will be hosted in three different CNRS laboratories: FEMTO-ST (TF Dpt), LPL and LTE hosted respectively by University of Bourgogne Franche-Comté, Sorbonne Paris Nord University (USPN) and Observatoire de Paris – PSL University. These three laboratories have a recognized expertise and complementary knowledge in the fields of time-and-frequency metrology and atomic physics.

The superradiant laser lab at LPL has extensive experience with studies of many-body phenomena arising in quantum gasses of ultracold atoms. They are developing a continuous superradiant laser based on a beam of cold strontium atoms. This future active optical clock will have access to the REFIMEVE network thanks to the presence of the network’s co-founder team at LPL.

University of CopenhagenThe Copenhagen group at the Niels Bohr Institute (NBI) is carrying out research on optical clocks and frequency references. The group has more than 17 years of experience working with cold two-electron atoms, such as Mg and Sr, for precision measurements and was the first to realize a BEC in Denmark using Na. Recently, the group demonstrated the potential of combining a low finesse optical cavity and atoms with narrow linewidth for bringing down local oscillator frequency noise and instability.

The Istituto Nazionale di Ricerca Metrologica (INRIM) is a public scientific research body which carries out and promotes research in metrology and develops the most advanced measurement standards and methods and related technologies, fulfilling the functions of a primary metrological institute. INRIM creates and maintains the national standards for units of measurement. Among its activities, the Time&Frequency group carries on research related to atomic frequency standards, such as the development of ultra-stable frequency references in the optical domain, fiber frequency transfer, development of techniques for detection and manipulation of ultra-cold gases, and tests of fundamental physics. A cavity-enhanced optical lattice clock based on strontium atoms is currently under development, experimenting advanced cooling, trapping and frequency stabilization techniques. It aims at merging quantum technologies experimented in the so-called cavity quantum electrodynamics (cavity QED) community with state-of-the-art optical lattice clock technology. It also pursues theoretical investigations of light-matter interactions in the full quantum regime, with particular attention to effects related to optical lattice clocks, such as ultracold collisions and entanglement (spin-squeezing) generation in collective atomic states.

The TU Wien contribution to the QuRIOUS project will be lead by Dr. Georgy A. Kazakov, who have been working over many years in the Quantum Metrology group lead by Prof. Thorsten Schumm. The Quantum Metrology group is working primarily towards a new type of atomic clock that will use the transition in the nucleus of Thorium-229 as a reference. The TU Wien group will develop theoretical models and simulate the behaviour of a superradiant clocks in the presence of various real-life effect, optimize of experimental parameters, and analyse the experimental data.
