This is the combined Part B paper for Quantum Mechanics and Electromagnetism and Quantum Theory and Quantum Computers. Its cover explicitly prints Part B and the joint label B7.1/C7.1. Section A belongs to the former course; section B belongs to the latter and is also present, with question numbers 1–3, in the separate Part C paper C7.1b, formal code DMAC 2A78. The combined paper is organized here under Quantum Mechanics and Electromagnetism; the standalone Part C paper belongs to Quantum Theory and Quantum Computers.
