Qubit
AvailableStates, amplitudes, and measurement probabilities
Establish the computational basis, the pure-state qubit model, and what measurement probabilities mean.

Course Roadmap
A carefully sequenced introduction to quantum computing, from the single-qubit model to interference and algorithmic reasoning.
States, amplitudes, and measurement probabilities
Establish the computational basis, the pure-state qubit model, and what measurement probabilities mean.
Coherence, phase, and interference
Define superposition as a linear combination and explain why phase information changes outcomes.
Basis, Born rule, and post-measurement state
Introduce the Born rule in the computational basis and clarify what collapse means in repeated experiments.
Unitary operations on state vectors
Study X, Z, and H as linear operators that rotate and reflect qubit states.
Correlations beyond separable states
Understand why some multi-qubit states cannot be decomposed into independent factors.
Composing gates into algorithms
Move from single operations to circuit reasoning with wires, gate order, and measurement placement.
How amplitudes reinforce or cancel
Analyze constructive and destructive interference as the mechanism behind quantum speedups.
From principles to algorithmic advantage
Connect core concepts to canonical algorithmic ideas and where quantum advantage actually comes from.
