I am not sure what it is about my way of stating things that is causing such severe comprehension problems for you (repeatedly). I never said that Computer Science is not deductive. In fact, the reason we even have a question over Computer Science being a science or not is that most of the things computer scientists do in practice are in fact deductive results about mathematical models. To be called a science, a field of study does however need to have a connection to the empirical world - and for computer science, C-T thesis is that connection.
Anyway, let me be the one bringing the discussion back to quantum computing this time. I don't think anybody in the world who could argue that study of entanglement - think Bell's theorem and CHSH inequality - isn't science. In fact, the 2022 Noble Prize for Physics was awarded to people who made foundational contributions on that field. I see Quantum Computing as a direct spiritual successor to that study.
