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 · 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
NPL's chief scientist, JT Janssen, explains how atomic magnetometers sense magnetic fields and how atom interferometers measure gravity, acceleration and rotation, including NPL's work on gravimeters based on a double rubidium atomic fountain: the sensors of Part 6, from the laboratory that built the first practical caesium clock. A long but rewarding lecture on fragile quantum states turned into precision tools.
Lecture · Heidelberg Laureate Forum
Heidelberg Laureate Forum · Charles H. Bennett & Gilles Brassard
"The Quantum Information Revolution from Wiesner to Turing": the inventors of BB84, and two of the six authors of the 1993 teleportation paper, lecture together as laureates of the 2025 ACM A.M. Turing Award. The Wiesner of the title is Stephen Wiesner, whose uncopyable quantum money (Part 2) set the whole story going.
Explainer · IBM Quantum
Qiskit · Katie McCormick
Katie McCormick walks through quantum teleportation for IBM's Qiskit in the Classroom series. Match each step to Part 4 (shared Bell pair, Bell-state measurement, two classical bits, Bob's X and Z corrections) and to the teleportation identity among the key equations.
Lecture · Perimeter
Perimeter Institute for Theoretical Physics · David Wineland
The 2012 Nobel laureate explores the theory and technology needed to build optical atomic clocks, in a public lecture at Perimeter Institute. Keep Part 6's comparison in mind (an optical transition ticks tens of thousands of times faster than caesium's microwave one), and remember that the record uncertainties quoted there came years after this talk.
Lecture · IAS
Institute for Advanced Study · Nathalie de Leon
Princeton's Nathalie de Leon gives the introductory lecture on quantum sensing with nitrogen-vacancy centres at the 2024 Princeton Summer School on Condensed Matter Physics, pitched at graduate students. Reread Part 6's diamond-sensor paragraph first (green-light spin readout, the 2.87 GHz resonance, about 28 GHz per tesla); the same defect serves as the network nodes in Part 7.
Lecture · Royal Institution
The Royal Institution · Kian van der Enden
A Royal Institution talk by a TU Delft quantum-internet researcher on what a quantum internet is and why we need it. Map what he describes onto Part 7's ingredients (entanglement, quantum memories, repeaters), and sort each application into 'demonstrated today' or 'still a goal'.
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 24. The whole course is in the Lecture Hall.
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.
