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•

Scientific highlights

Scanning Hall-Probe Microscopy

At the Institut NEEL, we develop many highly sophisticated scanning probes to use for a large variety of experiments under extreme conditions of magnetic field, low temperature and vacuum, as well as microscopes sensitive to charge, to currents, to magnetic fields, forces, electrical potential, to name just a few. Here, we wish to highlight a microscope which does not operate under extreme conditions but has the advantage of being extremely versatile. This microscope is a "Scanning Hall-Probe Microscope" (SHPM) which allows us to do direct, quantitative measurements of the spatial variation of a a magnetic field, that is to "map" the field.

Heat transport in the quantum regime has its own limits !

At extremely low temperature, the transport of matter, charge or energy through a very narrow "quasi one-dimensional" channel can be quantized. This has been demonstrated for a long time, for example for a current of electrical charges. Indeed, electrical conductance across a quantum dot takes values that are an integer multiple of the quantum of electrical conductance 2e2 /h, where e is the charge of the electron and h is the Planck constant. We expect to observe the same quantization phenomenon for heat currents, a regime that would no longer follow Fourier’s law, the classical law of heat conduction. As this quantization has been shown clearly for electrons and photons, it remains a mystery for phonons, the quanta of vibration of the crystal lattice. Full text.
