The AMADEUS project was presented by USTUTT at the Quantum Sensing GRC event held in Les Diablerets, Switzerland, from the 23rd to the 28th of July 2023.
The Quantum sensing GRC is a premier, international scientific conference focused on advancing the frontiers of science through the presentation of cutting-edge and unpublished research, prioritizing time for discussion after each talk and fostering informal interactions among scientists of all career stages.
The conference program includes a diverse range of speakers and discussion leaders from worldwide institutions and organizations, concentrating on the latest developments in the field.
In addition to the talks, the conference has designated time for poster sessions from individuals of all career stages, and allowed informal networking opportunities with leaders in the field through afternoon free time and shared meals.
Description of the poster presented :
Diamond nitrogen vacancy (NV) centers are a promising platform for quantum sensing with broad applications across multiple fields. High-concentration NV centers enable high-sensitivity magnetometry, offering significant potential for magnetic measurements. Compared to existing state-of-the-art magnetometry technologies, such as SQUID and OPM, NV-based magnetometry offers several advantages, including a larger dynamic range, frater bandwidth, and better spatial resolution.
They presented a magnetic gradiometer composed of two NV-based magnetometers that can resolve weak magnetic signals from a test object under high environmental magnetic field noise conditions. Their design and measurement results for the NV ensemble gradiometer demonstrate its potential for recording the magnetic signals produced by human brain activity. They also discuss the possibility of using this technology for Magnetoencephalography (MEG)measurements and brain-machine interface applications in an open environment. Overall, their study highlights the potential of NV-based magnetometry for advancing quantum sensing and brain imaging technology.
