Samuel Lellouch is an Assistant Professor in Digital Twinning at the University of Birmingham, where he is leading a research and innovation activity in the field of theory, modelling and simulation for quantum systems and quantum technologies. He is Co-Investigator at the UK Quantum Hub for Sensing and Timing.

Samuel is developing fundamental research on quantum systems in the aim to unveil new techniques that would enable the practical deployment of quantum technologies in real-life practical applications. He is especially interested in atom-interferometry-based quantum sensors and seeks to address challenges such as field resilience, sensitivity improvements and reduced system complexity via the development of new operation schemes, innovative atom-optics and post-processing techniques. Samuel is building full digital twins of quantum sensors and is collaborating with experimental physicists, engineers and key industrial partners to accelerate, via digital simulation, the manufacturing and industrial uptake of quantum sensors in applications relevant to positioning and navigation systems, space, civil engineering, and fundamental physics.

Samuel holds the Young Researcher Prize 2015 from the IFRAF/GdR Atomes Froids (France’s cold atom network).

Biography

Dr Lellouch graduated both as a physicist and an engineer from the Ecole Polytechnique (Paris). He obtained his PhD from the Institut d’Optique (A. Aspect’s group), Université Paris 11, on the theoretical study of many-body disordered quantum gases. Samuel then worked on the Floquet engineering of many-body quantum states, first at the Université Libre de Bruxelles, Belgium, and later on at the Université de Lille, France, through a two-year individual PRESTIGE mobility fellowship from the EU.

In 2019, willing to transpose his fundamental expertise to the development of quantum technologies, Samuel established his activities at the University of Birmingham, within the UK National Quantum Hub for Sensing and Timing, where he has led since then a theory, modelling and simulation workforce underpinning the development of cold-atom-based quantum sensors. In 2023, Samuel was appointed Assistant Professor in Digital Twinning. He is currently developing digital twins of quantum sensors in order to accelerate their uptake in real-life practical applications in positioning and navigation systems, space, civil engineering, and fundamental physics.

Research

Ranging from fundamental quantum science to applied quantum devices, Samuel’s activities aim at underpinning, via theoretical studies and digital simulation, the entire journey of quantum systems from the lab into practical industrial applications. They encompass the following research themes:

Optimized matter-light interactions

Coherent manipulation of quantum states using light lies at the heart of many quantum devices, from quantum sensors and quantum clocks to quantum computing and information processing. Samuel is conducting fundamental research on matter-light interactions in the aim to unlock new approaches to quantum state manipulation that would enhance the performance of quantum devices.

Atom interferometry

Atom interferometry is a critical technology where quantum interference between two wavepackets put in a quantum superposition is used to perform high-precision measurements of a desired quantity. Since its first proof of principle, it has matured to a versatile technology that is currently sought to be used in ultraprecise quantum sensors for metrology, geophysics, civil engineering, energy and resource harvesting, space and navigation. Through the development of comprehensive models, simulation tools and fundamental research on new schemes for atom interferometry, Samuel is driving solutions to enable the use of atom interferometry in real-life applications, and enhance the performance, resilience and technological readiness of atom-interferometry-based quantum sensors.

Digital twinning

Samuel is developing full digital twins of quantum devices in the aim to accelerate their uptake in real-life applications. This digital simulation capability would permit, among others, to test design options that would be too complex or costly in real life, including investigating the benefits of implementing the newest ideas from quantum theory, and to support fast trials, and later prototype development, with digital simulation.

Theory of ultracold quantum systems

Since the first experimental realization of a Bose-Einstein condensate in 1995, ultracold quantum gases have reached an unprecedented degree of control and versatility, becoming privileged simulators to investigate exotic properties of quantum matter, as well as potentially disruptive candidates for the future generation of quantum technologies. Samuel’s interests span the fields of periodically-driven quantum systems, many-body quantum systems, and ultracold quantum gases and condensed-matter theory.

Samuel collaborates strongly with a variety of industrial partners including Thales Alenia Space, MBDA, Teledyne-e2v and a diversity of academic collaborators such as MPQ Munich, NIST, and through the fundamental physics AION and AEDGE consortia.
