Quantum sensors emerged among quantum technologies as the ones with promising potential applications in near future. This perspective reviews two leading sensing platforms and their advancements toward biological applications: light sources color centers diamonds. light, including squeezed states N00N states, allows enhanced phase measurements by surpassing classical shot noise limits. advantage can be exploited several contexts, enabling improved resolution sensitivity, which are...
Individual, luminescent point defects in solids so called color centers are atomic-sized quantum systems enabling sensing and imaging with nanoscale spatial resolution. In this overview, we introduce based on individual nitrogen vacancy (NV) diamond. We discuss two central challenges of the field: First, creation highly-coherent, shallow NV less than 10 nm below surface single-crystal Second, fabrication tip-like photonic nanostructures that enable efficient fluorescence collection can be...

As theoretical studies continue to improve description complex mechanisms that regulate biological processes, in parallel numerous experiments are conducted enrich or verify these predictions also with aim extrapolating more accurate models. In fields magnetometry and thermometry, among various sensors proposed for application, nitrogen‐vacancy (NV) centers emerging as a promising solution due their...

Nitrogen-vacancy centers in diamond allow measurement of environment properties such as temperature, magnetic and electric fields at the nanoscale level, utmost relevance for several research fields, ranging from nanotechnologies to biosensing. The working principle is based on resonance frequency shift a single nitrogen-vacancy center (or an ensemble them), usually detected by monitoring photoluminescence emission intensity. Albeit schemes have already been proposed, search simplest most...
