測定の量子性を駆使した光量子センシング －顕微イメージング・分光応用に向けて－

抄録

Photonic quantum sensing is attracting attention since it outperforms photonic sensing with classical light. Here we present photonic quantum sensing that harnesses the quantum properties of not only light source but also measurement system. First, we introduce nonlinear interferometer as an approach to introduce quantum properties to measurement system, and then show our proposal and the theoretical results of a loss tolerant quantum absorption measurement. We also show photonic quantum sensing, which enables us to detect ultra-faint signal light at a photon counting level under huge noisy environments. We also discuss the future directions and challenges of photonic quantum sensing using the quantum properties of measurement system, including applications to microscopy and spectroscopy.
