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(note: for obvious public-relations reasons all names of conferences, PC members and authors in this post have been replaced by entirely fictional aliases).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
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

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

Quid qPCP?
This blog has already seen three posts on the quantum PCP conjecture: in February 2013 to highlight several talks at the Simons Institute in Berkeley, in October 2013 to promote a survey on the topic I wrote with Dorit Aharonov … Continue reading

QCryptoX: post-mortem
Our EdX/Delft/Caltech course on quantum cryptography officially ended on Dec. 20th, and is now archived (all material should remain available in the foreseeable future; we will also prepare a self-contained version of the lecture notes). At Caltech, the “flipped classroom” ended a couple … Continue reading
Two weeks in
Our course on quantum cryptography will soon enter its third week of instruction (out of ten weeks planned). My parallel “in-class” course at Caltech has already gone through four weeks of lectures. How is it going so far? There are many possible measures … Continue reading
One week later…
…and 736 words of expectation for the class: Note the top contender: let’s see if we live up to their expectations! It’s been a fun first week. We released “Week 0” of the material a month ahead of the official … Continue reading
