Quantum query complexity

Artem Kaznatcheev lecturing on quantum query complexityYou probably noticed a few things about TheEGG: a recent decrease in blog post frequency and an overall focus on the algorithmic lens — especially its view of biology. You might also be surprised by the lack of discussion of quantum information processing: the most successful on-going application of the algorithmic lens. I actually first became passionate about cstheory as a lens on science when I was studying quantum computing. In undergrad, I played around with representation theory and other fun math to prove things about a tool in quantum information theory known as unitary t-designs. At the start of grad school, I became more algorithmic by focusing on quantum query complexity. To kill two birds with one stone, I thought I would introduce you to query complexity and in doing so restore the more regular posting schedule you’ve been accustomed to. Of course, the easiest way to do this is to recycle my old writing from the now stale cstheory StackExchange blog.
