Course · Caltech
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 · 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.
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.
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 · CERN
CERN Lectures · Elías F. Combarro · 2020
The lecture from CERN A Practical Introduction to Quantum Computing (Elías F. Combarro, 2020) that goes with Chapter 21. The whole course is in the Lecture Hall.

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.
Demo · CIQM
Center for Integrated Quantum Materials · Michael Raymer
From 25:17, Henning Weier of the company qutools runs a live experimental demonstration of a Bell-inequality violation, so you see the correlations of this section measured on real equipment rather than computed on paper. The same lecture discusses possible loopholes at 49:47 and asks at 1:22:31 whether local realism fails.
Lecture · JQI
JQInews · Ronald Hanson
Ronald Hanson of QuTech in Delft, whose team ran the 2015 diamond experiment in this section, speaking in 2016 on 'From a loophole-free Bell test to a quantum Internet'. The start jumps to Bell's theorem as the CHSH game (19:18); then come what 'loophole free' demands (22:57), Bell's own event-ready-detector idea (27:27) and the first loophole-free test (42:04).
