Digital whiteboard teaching demo using OneNote posted on YouTube as part of the Caltech Adaptable Teaching Series

You can also click here to view some notes about how to use OneNote as a digital whiteboard for teaching.  Some of the specifics are tailored to Caltech, but hopefully the notes are easily applied elsewhere.  Watch the video above for a description of the advantages of this approach, but a primary advantage is the ability to have all the notes be viewable in a browser window in real time.  In other words, students can "scroll back" and see what you wrote a few minutes ago.

The Caltech Quantum Information Association (CQIA) is a new club at Caltech that we are happy to welcome!  From the website:

The association serves as a platform for members working on theory, experiment, and engineering in fields relevant to Quantum Information to exchange novel ideas and share expertise with resources. The goal is to foster strong ties and promote campus-wide multidisciplinary collaborations that lead to innovative research topics.

Check out the website for a list of events, and some recent blog posts about topological quantum computing, quantum computing in the near term, and of course our research
