Qu-Test is a partnership of European testbeds for quantum technology, which is composed of distributed infrastructures with globally unique equipment and competencies across Europe. The goal of the partnership is to provide European industry with the necessary support in terms of infrastructure and know-how to move faster to the market and create a robust supply chain for the quantum technology market. The partnership is aligned along three testbeds: quantum computing, quantum communication, quantum sensing. In more detail, the Quantum Computing Testbed will measure, characterise and validate cryogenic quantum devices, cryogenic qubits such as superconducting and semiconducting qubits, photonics qubits and ion traps provided by European industry, with an increasing service maturity and targeting larger quantum processors during the course of the FPA. The Quantum Communication Testbed will characterise devices for Quantum Key Distribution (QKD) and Quantum Random Number Generation (QRNG) and provide design and prototyping services to support innovation in the supply chain of quantum communication technologies. Finally, the Quantum Sensing Testbed will benchmark sensing and metrology instruments provided by industry and use a large suite of quantum sensors (clocks, gravimeters, magnetometers, imagers) to validate industrial use cases aiming at generating new business cases for quantum sensing and metrology devices. The three testbeds will be coordinated by a Single Entry Point (SEP) that will receive the requests of industry and direct them efficiently to the right testbed infrastructure. With additional services of IPR support, business coaching and innovation management, Qu-Test supports the European quantum industry with a holistic one-stop-shop to move the full ecosystem forward.

The field of matter-wave interferometry is emerging as a highly-promising interdisciplinary field, at the interface between fundamental science and quantum technologies/photonics/semiconductor European industry. The primary goals of MAWI are to use the exquisite control of ultracold quantum matter to implement guided matter-wave interferometers and to train young researchers in the emerging fields of matter-wave interferometry and quantum sensors based on interferometric schemes. The remit of MAWI is in the area of novel quantum sensing devices, with potential sensitivity enhancement of several orders of magnitude with respect to existing devices. Achieving this goal requires training the next generation of “quantum interferometry researchers” to a broad range of topics from fundamental to applied science, including both experimental developments and modelling, with strong connections to industry and emerging technological trends. Our training network focuses on the combination of optimal preparation of initial ultracold atomic sources and potentials to control and guide the atoms; their combination to build integrated guided atom interferometers for precision measurements, e.g., of rotations and accelerations; and technological advances towards their miniaturisation. The end goal of a fully-integrated cold atom quantum device could become a major commercial tool in the coming decade, complementing, or potentially even hybridising with, parallel developments in the photonics and semiconductor industries. Supported by our state-of-the-art facilities, our complementary expertise and skills, the participation of well-known European companies and a broad range of established external partners, we are poised to make lasting contributions to the scientific and technological developments of integrated matter-wave architectures and to the training of the next generation of research leaders who will propel quantum technologies even beyond our current expectations.

EURISA aims at ensuring long term availability of a European cost-effective and performant IMU based on fiber-optic gyroscopes and quartz accelerometers for the future space missions. As of today, all European missions depend on American IMU, mainly Northrop Grumman LN200S, with no alternative in Europe for compact and cost-effective IMU. The main goal of the project is to deliver an engineering model of this IMU at TRL equal or higher than 6. The engineering model will be tested in space environments and its inertial performances will be measured and validated. On top of that, the project will also deliver crafted hybridization algorithms to provide the best possible navigation performances EURISA relies on 4 actors of the European space ecosystem: Airbus Defence & Space, ETH Zurich, DLR Bremen and iXblue. They have all the required competencies and know-hows to make a success out of this project: space electronics, inertial sensors, knowledge on the space mission requirements, hybridization algorithms, space environment and also manufacturing and quality. In practice, the project will be built on current developments of the partners that have already reached TRL 4 and above: compact fiber-optics gyroscopes, quartz accelerometer, space electronic boards based on COTS and hybridization algorithms. In the frame of EURISA, these different elements will be further developed or adapted, then qualified and finally assembled together to make the future European IMU. By using current developments and many synergies together with the use of COTS, we ensure a cost-effective product and a safe path toward a TRL 6 maturity.

Optical clocks are amazingly stable frequency standards, which would remain accurate to within one second over the age of the universe. Bringing these clocks from the lab to the market offers great opportunities for telecommunications, navigation, sensing, and science, but no commercial optical clock exists. Europe's world leading optical clock technology within academia and national metrology institutes combined with its strong photonics industry, provide us with a golden opportunity to take a leading position in this strategic technology. With AQuRA we want to seize this opportunity and build up a sovereign, efficient industrial capability able to build the world’s most advanced quantum clocks. We will deliver the first industry-built, rugged and transportable optical clock with an accuracy that approaches the best laboratory clocks. Our work is based on the experience that many of us gained by building an optical clock with industry during the Quantum Flagship project iqClock (2018-2022). In AQuRA industry takes the lead and will deliver a 20x more accurate clock in a 3x smaller volume at TRL 7. This will be possible by combining our industry partners’ experience in rugged photonics products with the know-how of our world-leading academic and national metrology institute partners. We will build, strengthen and diversify the European supply chain of optical clock components, filling critical gaps in the supply chain, and thereby establish a sovereign, competitive industry for optical clocks. In particular we will develop the rugged laser sources, miniaturized optical interface circuits, and the atom source needed for an optical clock, all of which will also become products on their own. Partner Menlo Systems will integrate these components with their ultrastable laser system into the AQuRA optical clock. We will accelerate market uptake by demonstrating our clock's usefulness to applications in telecom, geodesy and metrology, and by engaging with end users.

Gravimetry aims at unveiling the density structure of the undergrounds by measuring subtle changes of the local gravity acceleration. The first-generation of quantum gravity sensors (QGs) has received a strong interest from many customers, and the market is still growing. But the commercial potential and the positive-impact of the technology are not yet fully exploited because of several limitations such as transportability, robustness, user-friendless or high operation costs. To overcome the barriers that limit the operational utilization of field gravimetry and develop the solutions that will allow us to fully address the exploitable market, we propose to conduct in FIQUgS the development of several innovations, either at the technological level with improved QGs built upon a reliable and efficient supply chain, or in terms of operational methodology. The development of a next generation QGs product line, and the services associated for the conduction of field surveys, data acquisition and data inversion will allow to considerably develop our capability to address the market of advanced geophysics. The unique industrial and technological capabilities that will result from FIQUgS will positively contribute to several important societal objectives, especially the European Green Deal: - the new field QGs will allow for a reduction of the environmental impact associated to mining activities thanks to a reduction of drilling operations, and civil engineering where it will contribute to more efficient and resilient constructions. - they will contribute to an improved utilization of geothermal energies through the development of non-invasive monitoring capabilities of the energy reservoir. - they will be involved in CO2 storage operations and will contribute to the fight against global warming thanks to these advanced monitoring capabilities. FIQUgS will also have an impact in quantum technologies markets, such as high-performance navigation or advanced photonics.
