What are the key differences between quantum and classical computing?

Classical computing uses bits as the smallest unit of data, while quantum computing uses qubits, which can represent multiple states simultaneously.

Can you explain how qubits work?

Qubits leverage the principles of superposition and entanglement, allowing them to perform complex calculations much faster than classical bits.

What are some practical applications of quantum computing?

Quantum computing has potential applications in cryptography, drug discovery, optimization problems, and complex simulations.

Are there any limitations to quantum computing?

Yes, quantum computing is still in its early stages, facing challenges like error rates, qubit coherence, and the need for low temperatures.
