Quantum research
The University of Luxembourg’s quantum research landscape spans theoretical and applied physics, quantum computing, quantum cryptography, and computational quantum mechanics. With recent investments, including the hiring of Prof. Marko Rancic in Quantum Computing, and strategic research funding from ERC and FNR, the University is strengthening its position for Luxembourg’s national quantum strategy.
Our quantum research areas
Traditional computers process information in bits (0s and 1s), but quantum computers use quantum bits (qubits) that can represent both 0 and 1 at the same time. This unique ability, along with other quantum properties, allows quantum computers to solve certain complex problems far more efficiently than classical computers ever could.
Quantum Algorithms and Technologies of Emulation in High Performance Computing group
Led by Prof. Marko Rancic, the group focuses on further strengthening the university’s expertise in quantum software, algorithms, and interdisciplinary quantum research.

– Design of quantum secure cryptographic algorithms
– Secure implementation of post-quantum algorithms
Quantum information theory studies how information can be stored, processed, and transmitted using quantum systems. It bridges classical information theory and quantum mechanics, exploring how quantum properties like superposition and entanglement can be used to process information in new ways. Think of it as the theoretical framework that explains why quantum computers can solve certain problems faster than classical computers, and why quantum communication can be completely secure.
Quantum Information Theory Group
Led by Prof. Adoldo del Campo, this research group investigates non-equilibrium quantum systems with applications to quantum science and technology, as well as the foundations of physics. Their work includes developing shortcuts to adiabaticity for quantum control, studying the dynamics of phase transitions and topological defects, exploring quantum speed limits and information geometry, and examining open and noisy quantum systems.
Research focus
-
– Non-equilibrium quantum systems and their applications in quantum science and technology.
– Quantum speed limits, information geometry, and shortcuts to adiabaticity for fast and robust quantum control.
– Open and noisy quantum systems and their behavior in real-world scenarios.
Quantum Dynamics and Control Group
Led by Prof. Aurelia Chenu, the group focuses on using noise as a resource to control the dynamics of quantum systems. Another line of research focuses on many-body quantum systems. By studying the spectral statistics of complex many-body systems, they are able to quantify the amount of integrability / chaos and infer how regular is the resulting dynamics. They also study energy transfer in systems from physical chemistry, such as networks of chromophores, relevant for the study of transport in the photosynthetic light-harvesting complexes.
Research focus
-
– Quantum decoherence and dissipation for quantum technologies (FNR Attract QOMPET).
– Quantum thermodynamics, studying how energy dissipation affects quantum systems.
– Quantum control and noise-resilient quantum systems.
– Spectral analysis of many-body quantum systems and diagnosing quantum chaos.
Applied Security and Information Assurance (APSIA)
APSIA’s mission is to develop and evaluate techniques to mitigate the multitude of cyber threats, and make the digital world more secure and trustworthy for its citizens.
Research focus
-
– design and verification of cryptographic protocols
– privacy-enhancing technologies
– secure voting and digital democracy
Quantum communication takes advantage of quantum properties to create highly secure data transmission systems. Because quantum states change when observed, any attempt to intercept the communication can be detected immediately. This makes quantum communication systems naturally resistant to hacking.

Quantum materials exhibit properties that emerge from quantum effects rather than classical physics. These materials can conduct electricity without resistance, respond uniquely to magnetic fields, or display other unusual behaviors. Researchers study them to develop better electronics, sensors, and energy technologies.
Theory of Mesoscopic Quantum Systems Group
Led by Prof. Thomas Schmidt, this group focuses on topological quantum systems, nonequilibrium quantum systems, and quantum spin systems. Their research aims to answer fundamental questions and develop ideas for applications in quantum technologies, such as robust quantum computation using quantum nanophotonic devices.

– Topological quantum systems for robust quantum computing.
– Nonequilibrium quantum systems, quantum coherence and transport in nanoscale devices.
– Quantum spin systems, investigating exotic quantum states and materials.
Quantum mechanics describes how atoms and particles behave at their smallest scales. Unlike our everyday world, where things are either here or there, quantum mechanics reveals a reality where particles can exist in multiple states simultaneously and interact in ways that seem to defy common sense.
Theoretical Chemical Physics Group
Led by Prof. Alexandre Tkatchenko, the group develops accurate and efficient first-principles computational and artificial intelligence frameworks to study a wide range of complex molecular and material systems, aiming at qualitative understanding and quantitative prediction of their quantum properties at the atomic scale and beyond. The group includes and collaborates with physicists, chemists, biologists, mathematicians, and computer scientists; both in theory and experiment.
