Randomness and interaction? Entanglement ups the game!

[05/25/19 Update: Kevin Hartnett has a nice article at Quanta explaining Natarajan & Wright’s result in slightly more layman terms than I’d be able to…see here: Computer Scientists Expand the Frontier of Verifiable Knowledge] The study of entanglement through the … Continue reading

Pauli braiding

[7/9/17 Update: Following a suggestion by Oded Regev I upgraded Section 1 from “probabilistic functions” to “matrix-valued functions”. This hopefully makes it a more useful, and interesting, mid-point between the classical analysis of BLR and the non-abelian extension discussed afterwards. … Continue reading

Foundations of randomness, Day 3

Last day! Wednesday started with a bang. Yevgeniy Dodis spent the whole Tuesday evening (our workshop dinner at Lanzerac!) complaining that we weren’t leaving him enough time to prepare for his talk…only to spend an equal amount of time during his talk … Continue reading
