On Quantum Metrology

 Admit had not heard of this application. 

Sabine Hossenfelder Quantum Metrology

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/srep1...

And the paper about quantum enhanced magnetometry is here:

Geometric phase magnetometry using a solid-state spin

K. Arai, J. Lee, C. Belthangady, D. R. Glenn, H. Zhang & R. L. Walsworth 

Nature Communications volume 9, Article number: 4996 (2018)

What are the quantum technologies that are now attracting so much research funding? In this video I go through the most important ones: quantum computing, quantum metrology, the quantum internet, and quantum simulations. I explain what these are all about and how likely they are to impact our lives soon. I also tell you what frequently headline blunders to watch out for.
