Compare and contrast at least four interpretations of quantum mechanics (e.g., Copenhagen, Many-Worlds, Pilot Wave, and QBism). For each interpretation, explain its core principles, how it addresses the measurement problem, and its conceptual framework for quantum entanglement and superposition. Discuss the philosophical implications of each interpretation regarding determinism, realism, and the nature of reality. Conclude by evaluating whether these interpretations can ever be experimentally distinguished from one another.
