Do we have the technology to play minigolf using subatomic particles?
If the particles become waves when no one is looking that is ok a little cheating and magic is in the spirit of minigolf handwaving.
I am NOT talking about making a putter and golfball and snapping a cute shot I am dead serious I want to play the tiniest golf possible.
The cooling reqiurement is a huge practical challenge - you’d need temps within a fraction of a degree of absolute zero to minimize thermal noise that would basically make your “ball” bounce around randomly like its constantly hitting invisible bumpers.
Yep. Hopefully the dilution refrigerators they use for quantum computers would work. Electrons are also easier than more substantial particles to keep still IIRC.
In hindsight, it’s obvious that the “club” should be an electrostatic field modulated in the RF range, not a laser. We’ve been carefully knocking electrons around with fields since Faraday, after all. The hardest part would be to incorporate a grid of minimally-invasive single electron detectors. And maybe the more whimsical obstacles, if you really want an electron windmill.
