What Is a Qubit? From Classical Bits to Quantum States
A ground-up introduction to qubits for developers who already know code. Bloch sphere, Dirac notation, the normalization constraint, and why a qubit is not just a probabilistic bit — with runnable Qiskit code.
beginner · ~18 min · prereq: High-school algebra, A little Python
- 02
Superposition, Measurement, and the Born Rule
Measurement turns amplitudes into probabilities and destroys superposition. This tutorial walks through the Born rule, measurement in different bases, the no-cloning theorem, and why you can't just peek at a qubit without breaking it — with runnable Qiskit code.
beginner · ~22 min · prereq: Tutorial 1: What Is a Qubit?
- 03
Multi-Qubit Systems and Entanglement
Tensor products, the 2ⁿ-dimensional state space, separable vs entangled states, the four Bell states, and why entanglement is the real secret ingredient of quantum computing. With runnable Qiskit code and a measurement-correlation experiment.
