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 · 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 · Royal Institution
The Royal Institution · Various speakers
Thirty evening talks from the Royal Institution's lecture theatre in London, where Faraday once lectured: quantum fields, quantum biology, sensors, the quantum internet and the meaning of it all. Pick any one; each stands alone.
Explainer · Fermilab
Fermilab
A short episode from Fermilab's Quantum Physics series with Don Lincoln and colleagues. Watch it alongside Chapter 1.
Explainer · Fermilab
Fermilab
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 · 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.
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.
Lecture · Royal Institution
The Royal Institution · Philip Ball
Science writer Philip Ball, author of the book 'Beyond Weird', starts from quantum physics' reputation as obscure and impenetrable and explores how its counterintuitive principles create the world we experience. Watch it beside section 4's five big ideas, and keep track of which claims are about experiments and which are about interpretations.
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.
