"Exploiting impurities in diamond for nanoscale measurements".
This event is over!
The NUMEV Seminars are open to a wide audience of students and researchers from all disciplines, who wish to learn more about the current research areas of the NUMEV-MIPS community (Mathematics, Computer Science, Physics and Systems) or about opportunities to develop their skills and know-how.

Quantum sensors are an emerging family of sensors based on the principles of quantum mechanics. These sensors are attracting growing interest because their performance is likely to exceed that of their classical counterparts. They use individual quantum objects characterized by extreme sensitivity to their environment. An emblematic quantum object in this field of application is an atomic defect in diamond crystal, known as the "NV center" (for Nitrogen-Vacancy). This defect behaves like an isolated atom, but is nestled in a matrix of the diamond crystal. In this presentation, we'll explain how such a defect can be used to create a high-performance nanoscale sensor to probe magnetic field, electric field, strain or temperature. We will then illustrate some application areas for this sensor, such as the field of modern condensed matter, for which these sensors are in the industrialization phase, and the more exploratory field of biological imaging and medical research.

Abstract
Quantum sensors are an emerging family of sensors based on the principles of quantum mechanics. These sensors are attracting growing interest because their performance is likely to surpass that of their classical counterparts. They use individual quantum objects characterized by an extreme sensitivity to their environment. An emblematic quantum object in this field of application is an atomic defect in the diamond crystal, known as the "NV center" (for Nitrogen-Vacancy). This defect behaves like an isolated atom, but is nestled within a diamond crystal matrix. During this presentation, we will introduce how such a defect can be used to create a high-performance sensor at nanoscales, to probe magnetic field, electric field, strain or temperature. We will then illustrate a few areas of application for this sensor. In particular, we will present two fields of application: modern condensed matter, for which these sensors are in the industrialization phase, and the more exploratory field of biological imaging and medical research.
