I think this is more about data processing while hiding the data from whoever operates the hardware. Homomorphic encryption could be a partial answer to that.

Explain please to me how homomorphic encryption will protect someone from basic laws of physics.

I hate your condescending tone, especially since you are clueless about that and don't seem to be able to perform a simple search

https://en.wikipedia.org/wiki/Homomorphic_encryption

The idea is to use a special encryption scheme (and associated operations). If I take 50 numbers and multiply them by two before asking you to add them, I'll just have to divide the result by two to get the correct answer, and you won't see the data nor the result. Of course, actual schemes are more complex than that.
