Homebrewing a Quantum Computer

Ok, now for something completely different, and something that might help us shake off that Ludite moniker. 

I've seen lots of videos that promise to explain what quantum computing is all about.  Most of them disappoint.  These videos have promise.  

This young lady built a very simple quantum computer at home using lasers and some calcite.  The homebrew angle is very interesting.  At one point in the second video she talks about the benefits of taking theory and using it to actually build something at home.  Indeed.  

I need to spend more time with both of these videos, but like say, they show promise, and they definitely show the spirit of homebrew.  

The first (above) describes the build.  In the second video (below) she uses the build to do a calculation.
