João Batalha and Luís Batalha are cofounders of Fermat’s Library.Fermat’s Library is a platform for annotating papers. Each week they send out a paper annotated by their community. Some recent papers were Birds and Frogs by Freeman Dyson and Von Neumann's First Computer Program by Donald Knuth.They’ve also built a Chrome Extension call Librarian for the arXiv which allows you to get direct links to references, do BibTeX extraction and make comments on papers.You can find them at FermatsLibrary.com.Read the transcript on our blog.The YC podcast is hosted by Craig Cannon.

Scott Aaronson is the David J. Bruton Centennial Professor of Computer Science at The University of Texas at Austin, and director of its Quantum Information Center. Before teaching at UT, he taught Electrical Engineering and Computer Science at MIT. His research interests center around the capabilities and limits of quantum computers, and computational complexity theory more generally.If you’ve listened to our other episodes about quantum computers and are curious to learn more, check out Scott’s book Quantum Computing Since Democritus.And if you want to read Scott’s blog you can find that at scottaaronson.com/blog/.Read the transcript on our blog.The YC podcast is hosted by Craig Cannon.

Henrique Dubugras is the cofounder of Brex, which provides corporate cards for startups.Anu Hariharan is a Partner at YC.Brex went through YC in the Winter 2017 batch and just closed their Series B, which was led by YC Continuity.In addition to discussing how the Brex team built out their service, Anu and Henrique also cover the specifics of what it takes to build a fintech startup in 2018.

Jared Friedman is a partner at YC and before that cofounded Scribd (YC S06).Matt Long a software engineer at YC and before that cofounded Crocodoc (YC W10).Today we’re talking about a project Jared, Matt, and several other people at YC have been working on. It’s called Work at a Startup and it’s like a common application for engineers to apply to many YC companies simultaneously.We’re also hosting a Work at a Startup Expo on July 28th in Mountain View where you’ll be able to meet 35 rapidly growing YC companies. You can learn more and apply to attend at workatastartup.com/expo.The YC podcast is hosted by Craig Cannon.

Simon Benjamin is a Professor of Quantum Technologies at Oxford. He is also the Principle Investigator for Oxford’s project on Quantum Optimisation and Machine Learning.This episode is more technical than last week’s episode with John Preskill. We start by covering some fundamentals then go into different approaches for constructing and scaling a quantum computer.Read the transcript here.The YC podcast is hosted by Craig Cannon.

John Preskill is a theoretical physicist and the Richard P. Feynman Professor of Theoretical Physics at Caltech.He once won a bet with Steven Hawking, which as he writes made him “briefly almost famous.” John and Kip Thorne bet that singularities could exist outside of black holes and after six years Hawking conceded that they were possible in very special, “nongeneric” conditions.In this episode we cover what John’s been focusing on for years: quantum information, quantum computing, and quantum error correction.Read the transcript here. The YC podcast is hosted by Craig Cannon.

Carola Schönlieb is an applied mathematician at the University of Cambridge. She’s also a Turing Fellow at the Alan Turing Institute and the head of the Image Analysis group at Cambridge’s Department of Applied Mathematics and Theoretical Physics.In this episode we cover mathematical approaches to image processing.The YC podcast is hosted by Craig Cannon.

Sean Mitchell is the cofounder and CEO of Rezi. REZI helps landlords find high quality, long-term tenants in 48 hours. They were part of the Winter 2017 batch.The YC podcast is hosted by Craig Cannon.
