Remember how superconductivity is about the complete (?) removal of friction thanks to quantum behaviour ?

Also this talk of quantum toys convinces me even more that the right framing is instead how our (subjective) information about a system can only decrease with time (or stay unchanging for exceptional systems such as these).

I was surprised superconductivity wasn't mentioned.

The new part here isn't the "perpetual motion" it's the complexity of the pattern.

I guess in some highly abstract sense it's like exciting a more complex resonance mode in a bounded system. The simplest mode gives you a simple output, more complex modes give you more complex outputs.

Superconductivity can be achieved at room temperature using pulses of electricity and vibration.
