This is the standalone Part C paper for Quantum Theory and Quantum Computers, held on Wednesday 15 June 2011, 9.30am–11.00am. Its three questions match questions 4–6 of section B in the combined Part B paper B7.1/C7.1, formal code DMAB 2686. The original solutions are reused here with the standalone question numbering, including the correction to the missing Fourier normalization factor.

Source release: Oxford examination archive release thread, Part C bundle pages 438–440.

Answer availability checked on 28 October 2026: bounded official-source searches by year, title, module and formal code found no exact full-paper or selected-part solution advertisement. The check was independent of any release policy for later years.

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.

Source release: Oxford examination archive release thread, Part B bundle pages 291–296. The sitting was Wednesday 15 June 2011, 9.30am–12.30pm.

Answer availability checked on 28 October 2026: bounded searches of official Oxford sources by year, course titles, module labels and both papers' formal codes found no advertisement of exact full-paper or selected-part solutions. Availability for these 2011 papers was checked independently of the later even-year policy described in the departmental examination overview.
