Quantum Computing 101
A focused path in six lessons through the ideas you need before solving Ketcode challenges.
Lesson 1
Qubits
Meet the qubit: amplitudes, probabilities and the state vector behind every circuit.
Lesson 2
Superposition
See why superposition is more than randomness: amplitudes interfere.
Lesson 3
Measurement
Turn amplitudes into data: shots, counts, collapse and measuring in other bases.
Lesson 4
Entanglement
Build Bell pairs and see correlations that no pair of separate qubits can produce.
Lesson 5
Quantum Gates
Learn the gates that rotate, flip and phase qubits, and how controlled gates connect them.
Lesson 6
Quantum Algorithms
Put it together: oracles, phase kickback, Grover search and Fourier patterns.
