Technical notes on linear matrix equations
[pdf]: On linear matrix equations
These are technical notes. As the title indicates, they’re not terribly likely to cause spontaneous celebrations in the streets, but contain material that may be of interest to people interested in quantum process tomography, the Solovay-Kitaev theorem, or quantum state estimation. Despite the format, these are not intended as a paper, and there’s little original content; they are primarily notes about work by other people that I think is interesting.
