Reference
A living reference to David Deutsch’s public work — talks, interviews, books, papers, essays, transcripts, and related primary sources.
Sources are reconciled across archives and platforms, duplicate representations are consolidated, and the record is updated as stronger sources are found and previously unavailable material resurfaces. The compendium will continue expanding and improving over time.
203 canonical works and appearances currently indexed.
The official book site remains useful for its synopsis, excerpts, errata, translations, and media indexes, but it currently renders PHP/Elementor deprecation warnings even though the underlying content still loads.

German-language interview with translator Dennis Hackethal. The exact upload day remains unresolved; the recording was public by September 2021. English-translation check (2026-08-06): Brett Hall hosts a complete English translation prepared by Jannik Wiese together with Dennis Hackethal, the original interviewer and German book translator.

Indiana University’s records identify Deutsch’s remote keynote on 2008-11-01. In August 2026, after an archival inquiry prompted by this compendium, Indiana University staff located the surviving legacy RealMedia recording in the web archive, converted and restored it through IU MediaSpace, and made a fresh public YouTube copy available. The recovered video runs 55:10. The preserved transcript remains available from IU and was later published as Deutsch’s chapter 28, pp. 551–566, in A Computable Universe (2012).

Technical six-lecture course: The Qubit; Interference; Measurement; The Schrödinger Picture; A Quantum Algorithm; Grover’s Search Algorithm. The public 2020 transcript is hosted by Indiana University and credits Ben Webb and Adrian German as its preparers; the existing GitHub resource is a backup mirror of that same loqcdd.pdf plus recovered worked examples. In 2026 correspondence, Indiana University staff confirmed that the transcript covers the Quiprocone videos represented by this DD-003 playlist and that permission to make it available had been received from David Deutsch in 2020. This is stronger provenance for an already-cataloged transcript, not a separate appearance.
