## About Thomas

I am a professor in the department of Computing and Mathematical Sciences (CMS) at the California Institute of Technology, where I am also a member of the Institute for Quantum Information and Matter (IQIM). My research is in quantum complexity theory and cryptography.
[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 →

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 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 →

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(note: for obvious public-relations reasons all names of conferences, PC members and authors in this post have been replaced by entirely fictional aliases).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

[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 →

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 →

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 →
