Some open problems
Here are some open questions that are of interest to me. You are welcome to get back to me with ideas or work on them on your own. You are welcome suggest problems that you would like to see on this list.
1. Consider the ground state of a two-dimensional system that is stabilized by holonomies corresponding to arbitrary loops on the plane. Which are the mathematical and physical conditions necessary to show that this system is topologically ordered.

Giandomenico Palumbo, Jiannis K. Pachos, to appear in PRL, arXiv:1301.2625.
2. Seeing Majorana fermions in time-of-flight images of spinless fermions coupled by s-wave pairing,

Symposia on Topological Quantum Information
These symposia take place every few months and typically last for two days. Their purpose is to bring together young scientists (mainly PhD students and Postdocs) interested on topological quantum information promote their recent work and inspire collaborations. Typically, there are a couple of tutorials and some research talks. Anyone can organize these symposia at their institute or university. Participants usually pay for their own expenses. The Leeds Centre for Topological Quantum Information provides some financial assistance. Please email me if you are interested in organizing one.
