John Preskill · 2021
The graduate course from the physicist who coined the terms "quantum supremacy" and "NISQ": density operators, measurement, channels, Bell inequalities, teleportation, circuits, Shor's factoring, Grover's search and quantum simulation. Advanced, and worth every minute.
Lecture · MIT
MIT OpenCourseWare · Allan Adams · 2013
A full MIT 8.04 lecture by Allan Adams. The first part previews quantum computing (the no-cloning theorem, met briefly in Part 5 and fully in Chapter 24, and the Deutsch–Jozsa algorithm of Chapter 23); the last part is devoted to the EPR experiment and Bell's inequality, the ideal bridge from this chapter to the next. Best watched after the lesson.
Lecture · Carnegie Mellon
Ryan O'Donnell
A whole Carnegie Mellon lecture on the CHSH game, the computer scientist's version of Bell's theorem, in terms of strategies and win probabilities. It is the rigorous treatment of this section's 75 versus 85.4 percent argument; watch it after the udiprod animation.
Lecture · Oxford
University of Oxford · James Binney · 2009–10
The lecture from University of Oxford Quantum Mechanics (James Binney, 2009–10) that goes with Chapter 21. The whole course is in the Lecture Hall.
Course · MIT
MIT OpenCourseWare · Allan Adams · 2013
Allan Adams' celebrated course starts from superposition and the experimental facts, builds the wavefunction, operators and the Schrödinger equation, then tours scattering, hydrogen, identical particles and band structure before closing on entanglement and Bell's theorem. Calculus and a little linear algebra are enough to keep up.
Lecture · Nobel Prize
Nobel Prize · Alain Aspect · 2022
"From Einstein's doubts to quantum technologies": Alain Aspect on his Orsay experiments of the early 1980s, which tested Bell's inequality with fast-switching polarizers, and on how entanglement went from philosophical puzzle to technological resource.
Lecture · Nobel Prize
Nobel Prize · John F. Clauser · 2022
"Experimental proof that nonlocal quantum entanglement is real": John Clauser on the 1972 Freedman–Clauser experiment at Berkeley, the first experimental test of a Bell inequality, and what it took to build it.
Lecture · Nobel Prize
Nobel Prize · Anton Zeilinger · 2022
"A Voyage through Quantum Wonderland": Anton Zeilinger on quantum teleportation, entanglement swapping and loophole-free Bell tests, told by the physicist whose group performed many of those experiments.
Explainer · IBM Quantum
Qiskit
IBM's Qiskit team builds Bell's inequality from scratch for newcomers, in the wake of the 2022 Nobel Prize. Watch for the moment an argument about 'reality' turns into an inequality that an experiment can check; today you will meet it as a single number, S.

PBS Space Time
Space Time's account of the 2022 prize goes deeper into why Bell's idea needed half a century of ever more careful experiments before physicists considered the case closed. Best watched after Parts 5 and 6, when the loopholes will make sense.
