Thread: People who know about Quantum Mechanics/Physics/Thoery Please come here

Quantum computing for me is my favorite "here and now, you can touch it and feel it" quantum topic. Bits on and off at the same
time .. the actual computer OFF and still able to work (according to a recent news story which may just be a little to overly optimistic). Observation however is still a problem so quantum computing is still moving at a slow pace but they do exist now .. multi-threading (the concept at least) taken to the n'th level thanks to Mr S's cat. How can a light (Qbit) be on and off at the same time and all states in between simultaneously? QM.
