The cryptographic leash
This post is meant as a companion to an introductory post I wrote on the blog of Caltech’s IQIM (Institute for Quantum Information and Matter), of which I am a member. The post describes a “summer cluster” on quantum computation … Continue reading

A beginner’s guide to PC chairing
I recently had the privilege to serve as program committee (PC) chair for the yearly conference on quantum cryptography, QCRYPT’17 (note: for obvious public-relations reasons all names of conferences, PC members and authors in this post have been replaced by entirely fictional aliases). Although … Continue reading
Unitary Correlation Matrices
Today I’d like to sketch a question that’s been pushing me in a lot of different directions over the past few years — some sane, others less so; few fruitful, but all instructive. The question is motivated by the problem … 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
Foundations of randomness, Day 2
Back to the fundamentals of randomness and our workshop in Stellenbosch – I want to discuss the remaining two days of talks! The second day started off with a whirlwind tour of the TCS approach to pseudo-randomness by David Zuckerman. David surveyed … Continue reading

Foundations of randomness, remainder of Day 1
Today I will cover the remaining talks from the first day of the workshop. Valerio’s opening talk was followed by a stimulating blackboard talk by Renato Renner, who asked the question “Is the existence of randomness an axiom of quantum … Continue reading

Foundations of randomness, Day 1: Scarani
As mentioned in the previous post, a highlight of the project I participated in over the past five weeks was the three-day workshop that we organized at STIAS towards the end of October. The purpose of the workshop was to … Continue reading

The nature of randomness and fundamental physical limits of secrecy
I spent the past five weeks at the Stellenbosch Institute for Advanced Study (STIAS), a research institute located in beautiful Stellenbosch, 40km North-West of Cape Town. I was participating in a program (“program” may be an ambitious term for a … Continue reading
Hypercontractivity in quantum information theory
In this post I’d like to briefly mention some connections between log-Sobolev inequalities, and more specifically hypercontractivity, with quantum mechanics and quantum information. To anyone interested I recommend the video from Christopher King’s excellent overview talk at the BIRS workshop. … Continue reading

Workshop on hypercontractivity and log-Sobolev inequalities in quantum information theory
A couple weeks ago I attended the workshop on “Hypercontractivity and Log Sobolev Inequalities in Quantum Information Theory” organized by Patrick Hayden, Christopher King, Ashley Montanaro and Mary Beth Ruskai at the Banff International Research Station (BIRS). BIRS holds 5-day … Continue reading
