Explorer les propriétés d’un qudit, élément clé de l’informatique quantique

Une équipe de l’Institut Néel a démontré qu’il est possible de contrôler de façon quantique un spin unique multi-niveaux porté par un aimant moléculaire – constituant un « qudit » – permettant ainsi son étude approfondie. La suite ici. Lire l’actualité scientifique. •02/2019•

Running a nano-engine just by looking at it

In quantum physics, measuring a quantum system can strongly perturb its state, which also affects the system’s energy. We have recently proposed a new kind of engine that, in theory, can extract work from such energetic fluctuations of purely quantum nature, induced by the measurement. This « nano-engine » adapts James Clerk Maxwell’s thought experiment (the "Maxwell’s daemon") to the quantum domain. Full text.

A Single-Electron Transistor breaks the law of thermal conductivity

Good conductors of heat are usually also good conductors of electricity. The celebrated Wiedemann-Franz law states that, at a given temperature, the thermal conductivity of a metal is proportional to its electrical conductivity. Yet, a joint group of researchers of the Institut NEEL and Aalto University (Finland) has led an experiment revealing that this law is violated in a specific quantum electronic device, a single-electron transistor.
