This European conference, organized at the Collège de France in Paris from June 4 to 6, 2024, aims to bring together two scientific communities to discuss the latest advances in knowledge of the fundamental aspects of quantum phenomena in hybrid superconductors and in the field of quantum devices and sensors in general.

Taking stock of the knowledge and the state of the art in quantum detection

The international conference "Quantum Sensing" is organized within the framework of the European SuperQuMAP project. It is funded by a COST Action (interdisciplinary scientific and technological research cooperation network) and by a few sponsors including the LNE.

The conference covers 5 fields of research and development:

- Superconducting single particle detectors

Superconducting single particle detectors are now the leading technology in terms of single photon detection performance. Their implementation is widespread in many fields, but there are still many open questions about the underlying microscopic physics and the development of new generations of detectors that are more efficient or operate at moderate cryogenic temperatures. These issues will be at the heart of this session.

- Sensors and devices for quantum optics and metrology

Quantum sensing uses quantum systems to enable or enhance sensing. The latest generation of quantum sensors and devices go beyond the standard quantum limit by using entangled states, but are not close to what is allowed by quantum mechanics. Convergence towards this ultimate limit is an open challenge in the field of detection.

- Quantum sensor-based microscopies and spectroscopies

The use of quantum sensors with ultimate sensitivity to locally probe the topographical and spectroscopic properties of matter is making it possible to penetrate the properties of materials and generate new functionalities.

- Novel phenomena and principles for quantum sensing

This session will be dedicated to all the emerging phenomena, theories and physical principles at the heart of quantum detection and the ultimate limit allowed by mechanics.

- Twistronic

This session is devoted to twistronic materials are all quantum-active interfaces from which nontrivial quantum phases emerge that are not intrinsic to the basic materials. From stacking, twisting, gate modulation and optical excitation, new fields of exploration in physics become accessible, enabling to travel from the limit of weak correlations to the limit of strong correlations, in a topological and many-body framework.
