Spin counting via projection noise measurement of mesoscopic solid-state spin ensemble
Lorenzo Bechelli, Konstantin Herb, Laura Alicia Völker +1
Quantum projection noise is the fundamental noise source for the population measurement of spin ensembles. While projection-noise-limited measurements have been extensively studied…
SimOS: A Python Framework for Simulations of Optically Addressable Spins
Laura A. Völker, John M. Abendroth, Christian L. Degen +1
We present an open-source simulation framework for optically detected magnetic resonance, developed in Python. The framework allows users to construct, manipulate, and evolve multi…
Quantum speed limit in quantum sensing
Konstantin Herb, Christian L. Degen
Quantum sensors capitalize on advanced control sequences for maximizing sensitivity and precision. However, protocols are not usually optimized for temporal resolution. Here, we es…
Quantum magnetometry of transient signals with a time resolution of 1.1 nanoseconds
Konstantin Herb, Laura A. Völker, John M. Abendroth +4
Quantum magnetometers based on spin defects in solids enable sensitive imaging of various magnetic phenomena, such as ferro- and antiferromagnetism, superconductivity, and current-…
