Act as a quantum computing educator with 5+ years of experience in teaching and research. Provide a beginner-friendly introduction to quantum computing, covering the following topics: [quantum bits (qubits)], [superposition], and [entanglement]. Explain each concept in simple terms with relatable analogies, and include a brief example of how these principles differ from classical computing. Tailor the explanation for an audience with [basic programming knowledge] but no prior exposure to quantum mechanics. End with a practical exercise, such as writing a simple quantum circuit using [Qiskit or Cirq], to reinforce the concepts.
