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.
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.
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 · Royal Institution
The Royal Institution · Jim Al-Khalili · 2025
A Friday Evening Discourse recorded at the Ri in November 2025, a century after Heisenberg's breakthrough: a hundred years of quantum theory, from the 1920s pioneers to the technologies being built now. Keep asking which claims are experiment and which are interpretation.
Lecture · Royal Institution
The Royal Institution · Sean Carroll · 2020
Sean Carroll tells the story from Planck and Einstein through Bohr, de Broglie and Schrödinger, then argues that the measurement problem is still open and makes his case for the many-worlds interpretation. Notice where the history ends and his interpretation begins.
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 · Royal Institution
The Royal Institution · David Tong · 2017
Cambridge's David Tong explains why the fundamental ingredients of the universe are fields, not particles, and how a handful of quantum fields in the Standard Model produce everything you can see. The perfect overture to Chapter 25.
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 · Fermilab
Fermilab
Fermilab's Don Lincoln on the electron's magnetic moment, the record-breaking agreement between quantum electrodynamics and experiment that Part 5 of this lesson describes. Six minutes on how a theory earns trust: with numbers that match.
Demo · Perimeter
Perimeter Institute for Theoretical Physics
A three-minute Perimeter Institute demonstration that measures Planck's constant with a cheap, simple setup built around LEDs. It makes section 3's exchange rate tangible, and it previews section 6, where an LED's colour is set by its band gap through E = hf.
