Topology is likely to be featured prominently in any truly useful quantum computation scheme.  The hurdle of scalable fault-tolerance is insurmountable with the current incremental progress -- while it is possible to engineer systems supporting hundreds of physical qubits, applications beyond academic interest require millions of qubits to implement robust error correction. Topological quantum computation (TQC) relies upon the preparation of topological phases of matter supporting non-abelian anyons to perform inherently fault-tolerant operations.  As errors are corrected at the hardware level through the topological nature of anyons, the problem of scalability is simultaneously overcome.  On the other hand, despite years of effort we still don't have unassailable confirmation that non-abelian anyons exist.

This workshop will bring together researchers in a diversity of fields in and around TQC for the purpose of broadening and deepening the subject, with an eye towards accelerating the realization of scalable technology.  We will explore new directions beyond the traditional anyon community,  embracing relevant topics such as quantum cellular automata, fractons, categorical symmetries and motion groups in 3-dimensions.

The participants will be a mixture of world experts and early career researchers from several fields in mathematics and physics from across the globe.
