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
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

UCSD Spring school on Quantum Computation
A couple months from now Dorit Aharonov, David Gosset and myself will be giving a short 3.5-day “Spring School” that is meant to be an introduction to recent topics in quantum computing, directed at young researchers in theoretical computer science at large. The school is … 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(note: for obvious public-relations reasons all names of conferences, PC members and authors in this post have been replaced by entirely fictional aliases).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
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
