# PHASE 1 - Concept Name: Quantum Superposition Definition: The ability of a quantum system to exist in multiple states simultaneously until observed. Real-World Importance: Forms the foundational computational advantage of qubits over classical bits. Mastery Question: Why can't a classical bit exist in multiple states at once? - Concept Name: Quantum Entanglement Definition: A phenomenon where two particles become deeply interconnected so that the state of one instantly dictates the state of the other. Real-World Importance: Enables secure quantum cryptography and ultra-fast teleportation of information states. Mastery Question: How does measuring one entangled particle affect the other?
