        "content": "Quantum computing harnesses quantum mechanics to process information in extraordinarily powerful ways. Unlike classical bits, which are 0 or 1, quantum bits (qubits) can exist in multiple states simultaneously through superposition. Qubits also entangle, allowing them to be interconnected in such a way that the state of one (whether it's 0 or 1) can depend on the state of another, no matter the distance between them. This combination of superposition and entanglement enables quantum computers to solve complex problems much faster than classical computers, particularly in areas like cryptography, optimization, and simulations of molecular structures. However, quantum computing is still in its early stages, facing challenges in stability and scalability.",
