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
