I'm a physics undergraduate who has just finished my first course in quantum mechanics, and while I can follow the mathematical formalism, the conceptual implications of phenomena like quantum entanglement still feel deeply counterintuitive and almost philosophical. I understand the basics of the EPR paradox and Bell's inequalities, but I struggle to reconcile the idea of instantaneous correlation with the principle of locality, and popular science explanations often seem to oversimplify or misrepresent the actual science. For those with a deeper background, what resources or thought experiments helped you develop a more robust, physically accurate intuition for entanglement beyond the "spooky action" metaphor? How do practicing physicists in fields like quantum information science conceptually and pragmatically deal with entanglement in their work, separating the established theory from the more speculative interpretations?
