QMAT — Quantum Sensors for Physi­cal Mater­ial Science

The project devel­ops a low-temperature, high-magnetic-field scanning quantum micro­scope based on NV-center quantum sensors to inves­ti­gate local mater­ial proper­ties at the 2D inter­face. By using multi­ple and entan­gled NV centers, the sensi­tiv­ity, spatial resolu­tion, and acces­si­ble frequency range are signif­i­cantly improved. The technol­ogy enables, for the first time, the visual­iza­tion and analy­sis of vortex dynam­ics in 2D super­con­duc­tors, thereby creat­ing a power­ful new tool for the study of quantum materials.

he project devel­ops a measure­ment platform for quantum sensing aimed at mater­ial analy­sis at sub-Kelvin temper­a­tures and high magnetic fields (up to 1 T). The goal is to extend spin-based quantum microscopy, in which single or few atomic sensors detect local magnetic and electronic proper­ties of materi­als, to extreme measure­ment condi­tions. To achieve this, NV centers in diamond are stabi­lized at very low temper­a­tures, their coher­ence times are improved, and mater­ial proper­ties as well as surface treat­ments are optimized. These devel­op­ments will enable reliable, high-resolution measure­ments for materi­als science applications.

By achiev­ing the stated objec­tives, new appli­ca­tion areas for quantum technolo­gies will emerge through the exper­i­men­tal charac­ter­i­za­tion and theoret­i­cal simula­tion of novel materi­als. The goal is to bring a new quantum sensing tool to the market that can make key contri­bu­tions to the research and devel­op­ment of emerg­ing quantum technologies.
