Maxwell imagined an entity, called a demon, that observes a system and uses the information it acquired to realise feats that are seemingly forbidden by the laws of nature (in this case, the second law of thermodynamics). Despite its fundamental and practical interest, the field of information thermodynamics is still in its infancy with very few experiments. Energetic footprints associated to the processing of classical information have been observed only recently. Besides, the burst of quantum information technologies has raised new questions: Is quantum information a new type of fuel leading to a thermodynamic advantage of quantum Maxwell demons with respect to their classical counterparts? Is it possible to design a Maxwell demon that operates in full autonomy and in the classical macroscopic limit? How is information defined in this regime?<\/p><figure class=\"wp-block-dev4-reusable-blocks-image  object-fit--contain\">\n    \n<img decoding=\"async\" class=\"wp-block-image unilux-custom-image-block\"\n                alt=\"\"\n            src=\"https:\/\/www.uni.lu\/wp-content\/uploads\/sites\/11\/2023\/07\/demon2.jpg\"\n                    style=\"object-position: 50.00% 50.00%; font-family: &quot;object-fit: contain; object-position: 50.00% 50.00%;&quot;; aspect-ratio: 21\/9; object-fit: contain; width: 100%;\"\n        loading=\"lazy\"\n\/>    <\/figure><p>Prof. Massimiliano Esposito and his co-investigators plan to answer several similar questions in their new project, building on a strong consortium of experimentalists and theorists having brought major contributions in the field, and taking advantage of mature experimental platforms.\u00a0\u201cOur team is remarkably interdisciplinary as it brings together two theorists and two experimentalists to address classical and quantum aspects of information thermodynamics\u201d explains Prof. Massimiliano Esposito. In particular, they will show that the inherent backaction of a measurement on a quantum system provides a new form of energy resource for engines. They will demonstrate the existence of this resource directly using superconducting circuits and use it for two kinds of Maxwell demons. Besides, they will use colloids and electrical circuits to show new types of autonomous Maxwell demons in the classical limit.<i>\u00a0<\/i><\/p><p><strong>The Foundational Questions Institute<\/strong><\/p><p>Founded in 2006, the\u00a0<a href=\"https:\/\/fqxi.org\" target=\"_blank\" title=\"\" rel=\"noopener\">Foundational Questions Institut (FQXi)<\/a>\u00a0is an organisation that provides grants to catalyse, support, and disseminate research on questions at the foundations of physics and cosmology, particularly new frontiers and innovative ideas integral to a deep understanding of reality, but unlikely to be supported by conventional funding sources.
