Life as a Physicist
Abstract: Sarah Croke - is a postdoctoral researcher at Perimeter Institute. From Ireland and the UK originally, she received a BSc in Physics and Applied Mathematics from University College Cork, Ireland in 2003. After a brief stint as a radio astronomer, completing an MSc in Astrophysics, she studied Quantu... read more

Randomness amplification
Speaker(s): Roger Colbeck
Abstract: I will discuss what we know about creating randomness within physics. Although quantum theory prescribes completely random outcomes to particular processes, could it be that within a yet-to-be-discovered post-quantum theory these outcomes are predictable? We have recently shown that this is not poss... read more

The uncertainty principle in the presence of quantum memory
Speaker(s): Roger Colbeck
Abstract: The uncertainty principle bounds the uncertainties about the outcomes of two incompatible measurements, such as position and momentum, on a particle. It implies that one cannot predict the outcomes for both possible choices of measurement to arbitrary precision, even if information about the prepara... read more

The impossibility of partially local hidden variable models for quantum theory and the relation to cryptography
Speaker(s): Roger Colbeck
Abstract: More than 40 years ago, Bell ruled out completely local hidden variable models as an explanation for quantum correlations. However, a new type of hidden variable model has recently been brought to light by the work of Leggett. Such a model has both local and non-local parts. Roughly speaking, having... read more
