I’m not sure what you mean by “equivalent of information theory but for computation”. Though it can be applied to other things, information theory is fundamentally about computation. Asking what its equivalent for computation is is like asking what the equivalent of a car is for driving on roads.
(Not that it seems to matter, but logic circuits go far beyond or, and and not gates. There are also nand gates, xor gates, really anything you can write a truth table for you can build a gate for.)
