Quantum sensing

Contact: Vincent JACQUES

Sensing using spin qubits is a rapidly growing field, enabling to probe a large variety of quantities. These quantities include magnetic field, electric field, pressure or temperature to name a few. Single spin qubits associated with the NV centers in diamond are outstanding in this respect, thanks to their long coherence time even at room temperature.

The main focus of the team is devoted to the use of NV-based sensors, enabling non-invasive, quantitative and vectorial magnetic field imaging with an unprecedented combination of nanoscale spatial resolution and ultrahigh magnetic sensitivity. These unique capabilities are applied to explore exotic spin textures in ferromagnetic nanostructures and to tackle fundamental problems in condensed matter physics at room temperature and in cryogenic environments.

NV centers are also attractive nanothermometers. Another research scope of the team aims at implementing wide field thermal imagers with nanoscale resolution. Such probes provide transformational capabilities with applications spanning from semiconductor technologies and manufacturing fields to bioscience and nanomaterials.
