10/14/22: Cryptography with Quantum States with William Kretschmer

William Kretschmer is a PhD student at the University of Texas Austin, advised by Scott Aaronson.  He's one of these pseudo-celebrity-grad-students with lots of cool splashy results and we're stoked that he took the time to talk to us today.  The talk primarily covered the basics of quantum cryptography, much of which should be familiar to regular group members who attended our quantum cafe series with Billy, but also concluded with some groovy quantum crypto history (see: quantum cash) and a discussion of exciting recent results by William & co.  This is one of a series of cryptography related talks we're hosting this semester, and William started that series out with a bang!  We hope you enjoy!
