Provide a comprehensive explanation of quantum entanglement theory, starting from its theoretical origins to modern interpretations. Discuss the EPR paradox, Bell's inequalities, and the non-locality principle. Compare and contrast different interpretations of quantum mechanics regarding entanglement, including Copenhagen, Many-Worlds, and Pilot Wave theories. Explore how entanglement challenges our classical intuitions about locality and realism. Conclude with the implications of quantum entanglement for fundamental physics and potential applications in quantum computing and communication.
