What is Quantum Metrology?

From the creator

Quantum mechanics is famous for its uncertainty principle that limits what you can measure. But oddly enough, quantum effects can actually help scientists make *better* measurements. This is what the field of quantum metrology is concerned with. In this video I explain what quantum metrology is and go through a few examples of what you can do with it. The paper I mention about quantum optical tomography is here: 0.54 μm resolution two-photon interference with dispersion cancellation for quantum optical coherence tomography Masayuki Okano, Hwan Hong Lim, Ryo Okamoto, Norihiko Nishizawa, Sunao Kurimura & Shigeki Takeuchi Scientific Reports volume 5, Article number: 18042 (2016) https://www.nature.com/articles/srep18042 And the paper about quantum enhanced magnetometry is here: Geometric phase magnetometry using a solid-state spin K.
