Nitrogen Vacancy Centers in Diamond for Quantum Biosensing: Magnetometry Techniques, Platforms and Applications
Sirsendu Ghosal, Umakant Prajapati, Sachin Negi +3
Quantum sensing using nitrogen-vacancy (NV) centers in diamond has emerged as a powerful platform for detecting ultra-low magnetic fields under ambient conditions. Owing to their l…
A Hybrid Jump-Diffusion Model for Coherent Optical Control of Quantum Emitters in hBN
Saifian Farooq Bhat, Michael K. Koch, Sachin Negi +2
Hexagonal boron nitride (hBN) has emerged as a promising two-dimensional host for stable single-photon emission owing to its wide bandgap, high photostability, and compatibility wi…
Femtosecond laser-written nano-ablations containing bright antibunched emitters on gallium nitride
Yanzhao Guo, Giulio Coccia, Vibhav Bharadwaj +5
Femtosecond laser-writing offers distinct capabilities for fabrication, including three-dimensional, multi-material, and sub-diffraction-limited patterning. In particular, demonstr…
Optical and microstructural studies of femtosecond laser treated amorphous germanium thin coatings
L. Kotsedi, A. Abdelmalek, V. Bharadwaj +8
The study of the relaxation mechanism of amorphous germanium after femtosecond laser irradiation is presented in this work. In particular, a thin germanium coating was deposited on…
Vector Magnetometry Using Shallow Implanted NV Centers in Diamond with Waveguide-Assisted Dipole Excitation and Readout
Sajedeh Shahbazi, Giulio Coccia, Argyro N. Giakoumaki +8
On-chip magnetic field sensing with Nitrogen-Vacancy (NV) centers in diamond requires scalable integration of 3D waveguides into diamond substrates. Here, we develop a sensing arra…
Laser-written waveguide-integrated coherent spins in diamond
Yanzhao Guo, John P. Hadden, Federico Gorrini +12
Quantum emitters, such as the negatively charged nitrogen-vacancy center in diamond, are attractive for quantum technologies such as nano-sensing, quantum information processing, a…
