Biography:

Nathalie Picqué is a research group leader at the Max-Planck Institute of Quantum Optics (Garching, Germany). She was previously a tenured research scientist with the Centre National de la Recherche Scientifique (CNRS) at Orsay (France). She received her doctoral degree in Physics from Université Paris-Saclay (France) in 1998. Her research interests are in the areas of optics and molecular physics, more particularly in interferometry, precision spectroscopy and laser technology. Her research focuses on exploring new ideas that involve laser frequency combs and on applying these novel concepts to metrology, molecular spectroscopy, holography and chip-scale sensing. A 2019 Optica fellow, Nathalie Picqué has received several awards, including the 2007 Bronze Medal of the CNRS, the 2013 Coblentz award in Molecular Spectroscopy, the 2021 Gentner-Kastler Prize in Physics, a 2021 European Research Council Advanced Grant, the 2022 Helmholtz Prize in Metrology and the 2022 Breakthrough in Physical Sciences of the Falling-Walls Foundation.

prof. Frederic Grillot of Telecom Paris and Univ. New Mexico, France

Semiconductor nanostructures with low dimensionality like quantum dots are one the best attractive solutions for achieving high performance photonic devices. In particular, quantum dots are currently experiencing a second revolution, in particular thanks to their very high potential for silicon photonics & quantum technologies. When one or more spatial dimensions of the nanocrystal approach the de Broglie wavelength, nanoscale size effects create a spatial quantization of carriers along with various other phenomena based on quantum mechanics. Thanks to their compactness, great thermal stability and large reflection immunity, semiconductor quantum dot lasers are very promising candidates for low energy consumption and isolation free photonic integrated circuits. When directly grown on silicon, they even show a four-wave mixing efficiency much superior compared to the conventional quantum well devices. This remarkable result paves the way for achieving high-efficiency frequency comb generation from a photonic chip. Quantum dot lasers also exhibit a strong potential for applications in optical routing and optical atomic clock. Last but not least, a quantum dot single photon source is a building block in secure communications, and therefore can be applied to quantum information processing for applications such as quantum computers. The talk will review the recent findings and prospects on nanostructure based light emitters made with quantum-dot technology. Many applications ranging from silicon-based integrated solutions to quantum information systems will be presented. In addition, the lecture will strongly highlight the importance of nanotechnologies on industry and society especially for shaping the future information and communication society.

Prof Christine Silberhorn of Dept. of Physics, University of Paderborn, Germany

Quantum technologies promise a change of paradigm for many fields of application, for example in communication systems, in high-performance computing and simulation of quantum systems, as well as in sensor technology. They can shift the boundaries of today’s systems and devices beyond classical limits and seemingly fundamental limitations. Current efforts in quantum photonics target the implementation of practical and scalable systems. Here the realization of controlled quantum network structures and multi-dimensional systems is key for many applications.

Here we review the progress for three differing approaches to overcome current limitations for the implementation of multi-dimensional photonic systems: non-linear integrated quantum optics, pulsed temporal modes and time-multiplexing.
