So we probably won`t be able to do anything with that alien spaceship.
It might use quantum computers that compare to our quantum computers
like my iPhone compares to an IBM 704 vacuum tube computer.
-------------------
Or it might use vacuum channel transistors which we do understand:
https://en.wikipedia.org/wiki/Nanoscale_vacuum-channel_transistor
That tech has advantages in space and doesn`t need the expensive and
difficult processing of our semiconductors.
"Theoretically, a vacuum-channel transistor is expected to operate faster
than a traditional solid-state transistor, and have higher power output and
lower operation voltage. Moreover, vacuum-channel transistors are expected
to operate at higher temperature and radiation level than a traditional
transistor making them suitable for space application."
There would be a considerable advantage for a long space voyage in a tech
more easily repaired than ours. We can`t fix either vacuum tubes or
transistors and have to replace them, while I`ve restored eroded car starter
electrical contacts by adding brass with a torch and filing it to shape.
This describes how to make a part as complicated as a centrifugal pump
housing from scratch, or by copying a broken original:
