QUANTUM INFORMATION
Prof. John Preskill, Caltech
Prof. John Preskill's legendary Caltech quantum computation lecture notes. The most comprehensive freely available resource on quantum computing and quantum information.
Physical vs logical gates, transversal Cliffords on the surface code, the Eastin-Knill obstruction, and the 15-to-1 magic state protocol that makes T gates fault-tolerant.
Learn how quantum error correction works by implementing the 3-qubit bit-flip code in Qiskit - encode a logical qubit, introduce an error, detect it with syndrome measurement, and correct it.
Understand why Clifford+T is the universal fault-tolerant gate set, the cost of T gates in magic state distillation, and how to analyze T-count with PennyLane.
