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.

Fermilab's Dr. Don Lincoln explains what the phrase 'quantum entanglement' means and how two objects can be linked by quantum effects. As you watch, keep two questions in mind: what exactly is correlated, and could anything in the setup carry a message? Part 5 of the lesson settles the second question with a two-line calculation.
Lecture · IQOQI Vienna
IQOQI Vienna · Christoph Lehner
An hour-long history-of-physics talk at Vienna's quantum-optics institute on Schrödinger's part in the making of the Einstein–Podolsky–Rosen paradox. Watch it after this section for the 1935 story at research depth, told from the side of the man who gave entanglement its name (Part 1).

The Joint Quantum Institute introduces parametric down-conversion, 'a fascinating phenomenon with a forbidding name': a single photon enters a special crystal and two photons come out. Watch it before this section's energy bookkeeping, 1/λ_pump = 1/λ_signal + 1/λ_idler, which says where the parent photon's energy goes.
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.
Explainer · Perimeter
Perimeter Institute for Theoretical Physics · Katie Mack · 2023
A short episode from Perimeter Institute's Quantum 101 series with Katie Mack. Watch it alongside Chapter 20.
Series · Perimeter
Perimeter Institute for Theoretical Physics · Katie Mack · 2023
Ten five-minute episodes hosted by the cosmologist Katie Mack: duality, quantization, uncertainty, superposition, entanglement, probability, tunnelling and quantum computing. The friendliest possible on-ramp, and a quick refresher before any chapter.
Series · Fermilab
Fermilab · Don Lincoln and colleagues
Short, precise episodes from Fermilab, many with Don Lincoln: what quantum mechanics is really about, entanglement, quantum electrodynamics and chromodynamics, quantum field theory and quantum foam, plus a look inside the lab's quantum-computing and networking work.
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.

Looking Glass Universe
A short, careful argument for why entangled particles cannot carry messages, using the same Alice-and-Bob setup as Part 5. The video speaks of the particles 'affecting' each other; treat that as one way of talking (Part 5 explains why it is interpretation-dependent) and focus on the proof that Bob's results stay random.
