- [[Tiny]] things [[tunnel]] through stuff, but how?
-
Quantum computers must be [[cold]] to maintain [[coherence]].
collapsed:: true
-
[[Perfect]] models of tiny things are possible. So we can [[check]] for [[proof]] of [[predictions]] about how [[materials]] will behave.
collapsed:: true
- Seeing how metals may bend before we make them.
- How air might move around a plane before building it.
- How food might taste.
- How strong buildings might be.
-
Instead of on/off [[switches]], these sending [[signals]] in a [[wave]] that [[spreads]].
- This is what we need to make things [[cold]] and use [[lasers]] for- because it might get too chaotic to get any [[signal]] we can understand out of it.
