We study quantum theory, information theory and the interplay between these fields. We explore applied and fundamental questions related to the certification, the quantification and the development of resources for quantum technologies.
Berkeley Lab’s Applied Mathematics & Computational Research (AMCR) Division develops the full stack of technologies that turn the world’s most powerful computers into engines of discovery. Our researchers advance mathematical modeling, large-scale simulation, novel algorithms, programming models, computer architectures, systems software, and performance optimization—melding these elements into high-performance codes that push scientific boundaries.
We investigate the fundamental principles of quantum information processing and complex quantum many-body systems. Using methods from mathematical physics, quantum information theory and computational science, we seek a deeper understanding of quantum phenomena while addressing the fundamental challenges underlying emerging quantum technologies. Our research spans quantum computing, quantum error correction, quantum algorithms, quantum communication and the study of strongly correlated quantum matter.
Département Communications, Images et Traitement de l'Information (CITI) is a research group located at Télécom SudParis, Institut Polytechnique de Paris. It specialises in various aspects of information processing (such as classical and quantum information and communication theory, signal and data processing, and machine learning), as well as applied mathematics.
Welcome to the Quantum Simulation and Computation Group at University of Portsmouth!
We are interested in a wide range of topics in quantum information and quantum computing connected to understanding the power and limitations of near-term quantum devices. As a major tool, we are using random quantum circuits to better understand the generic expressitivity of short quantum circuits.
Research focus:
- random unitaries and designs
- quantum learning theory
- quantum computing resources
- benchmarking and characterization
- classical simulation
Many-body light-matter systems are hybrid open quantum systems exhibiting both strongly correlated behaviors of matter and (in)coherent features of photons. They have emerged as a novel platform for studying nonequilibrium many-body quantum dynamics as well as for implementing new quantum technologies.
Our group was established at Lund University, Sweden, in 2023. The research is broadly within the field of quantum information theory and the foundations of quantum mechanics.
Typical focus points are entanglement, nonlocality, prepare-and-measure scenarios, quantum cryptography, quantum measurements, certification of quantum devices, semidefinite programming techniques and fundamental concepts of classical vs quantum.
