[Date] Apr 25 [Speaker] Professor James Thompson Precision Measurement and Atomic, Molecular and Optical Physics [Title] 
“Quantum Fuzziness and Quantum Certainty” Late at night, the world can look fuzzy to tired eyes. Thankfully, a pair of reading glasses or a good night's sleep will make things clear again. However, in the quantum world there is a fundamental fuzziness that cannot be fixed with glasses or a good night's sleep. Remarkably, this fundamental quantum fuzziness is responsible for keeping the stuff you and I are made out of from collapsing, and is the key to making atomic clocks that are accurate to a few parts in a billion billion. The quantum fuzziness does eventually serve to blur our best measurements of the world around us. We will discuss both the quantum certainties and uncertainties created by quantum fuzziness, and how we use quantum entanglement to stitch together laser-cooled and levitated atoms to reduce their total quantum fuzziness.
