Notes on quantum information and quantum computing, starting from classical states, probability vectors, Dirac notation, tensor products, quantum states, measurement, and unitary operations.

Qiskit Lesson 2: Multiple Systems Compound classical and quantum systems, Cartesian products, tensor products, marginal and conditional states, CNOT, Bell states, partial measurement, and local unitary operations.

Qiskit Lesson 1: Classical and Quantum Information Classical states and probability vectors, Dirac notation, deterministic and stochastic operations, quantum states as complex unit vectors, measurement, and basic qubit gates.
