I held a talk at the Quantum Technologies Meetup hosted by IBM in Munich on 2019/04/04. It was a gentle introduction to topological quantum codes as means of quantum error correction, adapted for a diverse audience.
For anyone who may be interested, the slides have been plopped down here. If you came by to say hello at the event, thank you for the lovely feedback and nice chats! You can always contact me with any questions — I'd be happy to help.
