Invited Talk

Dr. Gesa Welker, Eindhoven University of Technology
Quantum sensing is one of the pillars in the currently ongoing second quantum revolution. In my talk, I will explain how impurities in diamond, quantum sensors of just the size of an atom, can detect extremely tiny magnetic fields. Such so-called color centers in diamond are used for many applications, they have e.g. been used to map the...

Prototypical Color Centers in semiconductors, such as the $\mathrm{NV^-}$-center in diamond, the Silicon vacancy ($\mathrm{V_{Si}^-}$) and the di-vacancy ($\mathrm{V_{C}V_{Si}}$) in 4H-Silicon carbide (4H-SiC) are promising candidates for the implementation of quantum bits (qubits) in semiconductors. Their coupled electron spins exhibit correlated high- and low-spin states,enabling...

18. Quantum sensing with spin defects in emerging platforms beyond diamond

Contributed Talk

Optically addressable spin systems, such as nitrogen-vacancy (NV) centers in diamond, have been widely studied for quantum sensing applications. Recently, our group demonstrated two novel quantum sensing platforms based on naturally occurring spin defects in boron nitride nanotubes (BNNTs) (1,2). These defects combine high surface area with omnidirectional spin control—key features that...

Over the past decade, nitrogen-vacancy (NV) centers in diamond have emerged as a powerful platform for quantum sensing, generating increasing interest in biomedical applications due to their high spatial resolution, inherent biocompatibility, and ability to operate under ambient conditions. One of the key advantages of NV-based sensors is the chemical and mechanical robustness of the diamond...
