Quantum-enhanced Sensing with Spin Defects in Diamond

Abstract

The next-generation quantum technologies enabled sensors, i.e., the electronic-spin-dependent fluorescence associated with nitrogen vacancy (NV) centers in diamond, offer great potential to detect localized events at ambient condition, in a quantitative and minimally invasive manner. In this talk, I will give an overview of quantum sensing with NV centers, especially its potential applications in life science. As an example, I will highlight one of our recent work on developments of programmable diamond quantum sensor for monitoring various physical quantities in microfluidics1. Taking advantage of the unique quantum features of NV centers in diamond, together with their excellent biocompatibility and extraordinary long-term working capability, I will discuss the possibilities that may lead to a number of excitements ranging from measuring mechanical forces, to imaging magnetite biominerals associated with neurodegeneration.
