Understanding Superposition: A Beginner's Guide
D
Dr. Sarah ChenSuperposition is one of the fundamental principles of quantum mechanics. Unlike classical bits that can be either 0 or 1, a qubit can exist in a superposition of both states simultaneously.
Key Concepts
- Classical vs Quantum: A classical bit is like a coin lying flat — heads or tails. A qubit is like a spinning coin.
- Measurement: When we measure a qubit, it "collapses" to either 0 or 1.
- Bloch Sphere: We can visualize a qubit's state on the Bloch sphere.
