Will TSM become the ultimate fab for quantum chips?

Many companies are working on quantum chips, but TSM with the technical expertise in manufacturing and the number of high-end fabs, could be the best option for making quantum chips in large quantities. Any thoughts or comments on this appreciated.
 
AFAIK, the core physical hardware for the "CPU" part of quantum computing doesn't require many chips and is fabbed in mature processes from about 180nm down to 22FDSOI. The requirements are closer to RF than leading edge digital. Of course, the surrounding control, measurement and especially error correction systems are done in leading edge processes. But I'm not sure volumes scale the way they do for AI.
