Course · IBM Quantum
Qiskit · John Watrous · 2022–25
The clearest modern course on quantum information, from IBM Quantum's John Watrous: single and multiple systems, circuits, teleportation and superdense coding, Shor's and Grover's algorithms, density matrices and error correction. Mathematically honest without being heavy.
Course · Stanford
Stanford · Leonard Susskind · 2006
Nine evenings on the strangest resource in physics — spin, density matrices, entangled states and Bell's theorem — taught by Susskind to a room of non-specialists. Pairs naturally with Unit 5.
Lecture · Perimeter
Perimeter Institute for Theoretical Physics · Shohini Ghose · 2020
Physicist Shohini Ghose of Wilfrid Laurier University surveys the quantum technologies that grow out of superposition and entanglement, from quantum computers to secure communication. A clear public lecture given at Perimeter Institute in March 2020.
Lecture · Nobel Prize
Nobel Prize · Serge Haroche & David J. Wineland · 2012
Serge Haroche on trapping photons in a box to watch the quantum-to-classical boundary — decoherence — in action, then David Wineland on superposition and entanglement with trapped ions. The experiments that turned thought experiments into laboratory routine.
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.
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 · IBM Quantum
Qiskit · John Watrous · 2022–25
The lecture from IBM Quantum Understanding Quantum Information & Computation (John Watrous, 2022–25) that goes with Chapter 20. The whole course is in the Lecture Hall.
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.
Panel · World Science Festival
World Science Festival · Brian Greene with David Z. Albert, Sean Carroll, Sheldon Goldstein and Ruediger Schack · 2014
Physicists and philosophers of physics argue about what a measurement really is — Bohmian mechanics, many worlds and QBism side by side — with Brian Greene keeping score. Ideal companion to Chapter 22: every position is an interpretation, and all of them agree with experiment.
