Just out of curiosity, lets say [hypothetically], I had a PC that used

run into something similar to "leakage current"? If so, what is the
optical equivalent of leakage current?

Optical damping. Well, leakage current is unavoidable when you can't turn
supplies off, because you need it to remember states of flip-flops or such
like. If you figure out how to have a persistent storage within a
flip-flop, that doesn't need power, you can avoid leakage by powering up
the systen only when you need it.

Core? MRAM?

You lose energy in the powering up process. You can have
ferroelectric material in the chip to store the bits without power.

Another way to go would be to make mechanical memories with MEMs
technology.
