Overly sensitive: the journey towards quantum sensors
In this meetup, Lia will describe how to create the largest quantum object in the universe and how it can be used for quantum sensing.
Quantum technology is apparently the next big thing, with the UK spending £270 million for the National Quantum Technology Programme, the EU committing €1 billion to its Quantum Flagship initiative & the recent signing of the $1.2 billion National Quantum Initiative Act by President Trump. But which quantum devices can we expect to see in our future daily lives? How sensitive is too sensitive? And what new measurements could be achieved? In this talk, Lia will describe how to create the largest quantum object in the universe and how it can be used for quantum sensing. She’ll explain the impracticalities of quantum sensors for consumers and describe the benefits of hybrid systems which can operate in both classical and quantum regimes. One example is her optical motion detector which is sensitive to movements smaller than the size of a single atom and can be used to monitor acceleration of blood through the heart.
Dr. Ying Lia Li (Lia) completed her Ph.D. at University College London where she is currently an EPSRC Doctoral Prize Fellow working on optical inertial sensors for GPS-denied navigation. Prior to her Ph.D. Lia worked at BAE Systems as a research scientist, specialising in optical fibre systems for Eurofighter Typhoon. In 2012, she was a UK Famelab Finalist and continues to champion science through public engagement activities like the UCL Women in Physics Group, and collaborating with artists to transform public perception of physics.
