In the Fall, Boaz and I co-taught a grad seminar on physics and computation (see here for some of the original press coverage). We were lucky to attract an intrepid group of students from multiple fields, with representatives from computer science, physics, math and biology. As part of the course, we asked our students to … Continue reading Physics & Computation Blog Post Round-up
Nominate TCS papers for research highlights
[Guest post by Aleksander Mądry] To me, one of the best things about working in theoretical computer science has always the exciting rate of progress we make as a community. On (what appears to be) a regular basis, we produce breakthroughs on problems that are absolutely fundamental to our field. Problems that often look impossible to tackle, right … Continue reading Nominate TCS papers for research highlights
News addicts: Sign up for the CATCS newsletter
If, like others following the pace of modern life, you're the kind of person that needs to get just on time updates on the state of theoretical computer science, consider signing up for the newsletter of CATCS. You can get information about funding opportunities, advocacy efforts, and more. Sure, at the hectic rate of two … Continue reading News addicts: Sign up for the CATCS newsletter
Submit your failures to CFAIL 2019
[Posted at the request of Craig Gentry. I think this is actually a great idea that should be imitated by other sub-areas of TCS as well. --Boaz] Update: The Conference for Failed Approaches and Insightful Losses in cryptology is celebrating our first failure early: the failure to keep a deadline! We are extending the submission … Continue reading Submit your failures to CFAIL 2019
Black Holes, a Complexity Theory perspective
Guest post by Chi-Ning Chou and Parth Mehta from the physics and computation seminar. Abstract The firewall paradox (introduced here) is a bewitching thought experiment that mandates a deeper understanding of our reality. As luck would have it, QFT predictions seem sound, GR calculations appear valid, and semi-classical approximations look reasonable: no one is willing … Continue reading Black Holes, a Complexity Theory perspective
Black hole paradoxes: A conservative yet radical journey
Guest post by Abhishek Anand and Noah Miller from the physics and computation seminar. In 2013, Harlow and Hayden drew an unexpected connection between theoretical computer science and theoretical physics as they proposed a potential resolution to the famous black hole Firewall paradox using computational complexity arguments. This blog post attempts to lay out the … Continue reading Black hole paradoxes: A conservative yet radical journey
Introduction to AMP and the Replica Trick
(This post from the lecture by Yueqi Sheng) In this post, we will talk about detecting phase transitions using Approximate-Message-Passing (AMP), which is an extension of Belief-Propagation to “dense” models. We will also discuss the Replica Symmetric trick, which is a heuristic method of analyzing phase transitions. We focus on the Rademacher spiked Wigner model (defined below), … Continue reading Introduction to AMP and the Replica Trick
Quantum circuits and their role in demonstrating quantum supremacy
There's a lot of discussion and (possibly well-deserved) hype nowadays about quantum computation and its potential for computation at speeds we simply can't reach with the classical computers we're used to today. The excitement about this has been building for years, even decades, but it's only very recently that we've really been approaching a solid … Continue reading Quantum circuits and their role in demonstrating quantum supremacy
Looking a postdoc opportunity?
This is the season that people are applying for postdoc positions. Unlike student and faculty hiring, which each have a fairly fixed schedule, postdoc availability can change from time to time, with new opportunities opening up all the time. So, I encourage everyone looking for a postdoc position to periodically check out https://cstheory-jobs.org/ . (For … Continue reading Looking a postdoc opportunity?
Why physicists care about the Firewall Paradox
[Guest post by Noah Miller - a Harvard Physics Ph.D student that took our seminar. Noah's webpage contains wonderful and extensive notes that can be of interest to computer scientists. --Boaz] (The following blog post serves as an introduction to the following notes:) Black Holes, Hawking Radiation, and the Firewall There are many different types of "theoretical physicists." There are theoretical … Continue reading Why physicists care about the Firewall Paradox
