I will describe the route that took us from experimental work on a new packing problem (looking for "codes" in Grassmann manifolds - e.g., how should you place 18 planes through the origin in Euclidean 4-space so that they are as far apart as possible?) to the construction of codes for quantum computers. This work began as a project with Ron Hardin and John Conway, but many others (Peter Shor, Rob Calderbank, Eric Rains, Gabriele Nebe, ...) have since been involved. There are also applications to medicine, to visualizing multi-dimensional data, and to wireless communications.
