Francesca Falzon is closing off the talks. Audience still going strong :)

Nice #C4DT_EPFL topic on how to design privacy preserving protocols for private set intersection. Specifically what questions you need to ask...

Michael Vergoz is showing business challenges with post quantum algorithms. Well beyond reviewer #2 :)

#SwissCryptoDay25

Ziyi Guan talking about SNARGs in ROM. I'm actually enjoying understanding a word from time to time :)

Completeness and Soundness are also on every slide of Alessandro's course...

OK, this is not POST-quantum, but REAL quantum. Presented from Giulio Malavolta: how do you prove you're communicating with a real quantum computer, and not a fast classical computer? In as little steps as possible, of course.

Quantum joke: "And finally - we need experiments" - audience laughs...

More dressups! It's getting difficult to distinguish dresses with people actually dressing up nicely :) Which one is no dress?
