The only real connections I can think of is MRI machines - they use quantum mechanics to work. http://en.wikipedia.org/wiki/MRI
I'm sure many people would be tempted to go down the route of alternative medicine and things like 'touch therapy', which don't work at all and claim quantum mechanics as the guiding principle, but it's a load of crap, and chances are your professor knows that. At least I really, really hope they do.
