I think in your list of examples there are plenty of cases where nature, while not building the exact thing uses the same underlying principles.

There are a lot of seeds that are aerodynamic so that they get spread more widely for example. Even seeds that have controlled falls due to "autorotation"

But of course on planet earth at least it is hard for nature to use things requiring too high or low temperatures. Nature doesn't need the Haber process, but it does fixate nitrogen.

Right, so life could make use of quantum transitions that are used in quantum computing, without actually doing or using the results of quantum computations.

If your standards are low enough that you would say superconductivity appears in nature, then quantum computing certainly does.

So, no, superconductivity probably does not exist in nature

[knzhou]

Most candidates for quantum computing also require extremely low temperatures — in fact, lower than the ones for superconductivity.
