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 · Katie McCormick
An episode of Qiskit in the Classroom in which Katie McCormick works through Deutsch's algorithm and then the Deutsch–Jozsa algorithm of this section, setting quantum against classical. As you watch, map each step onto this section's three moves: Hadamards spread the input, the oracle writes f into the signs of the amplitudes, and Hadamards fold the paths back together.
Lecture · Centre for Quantum Technologies
Centre for Quantum Technologies · Volodymyr Sivak (Google Quantum AI)
A CQT colloquium by Volodymyr Sivak of Google Quantum AI that shares its title with Google's Nature paper reporting the experiment on the Willow chip. Expect the research-level version of this section's story, aimed at physicists: what it takes for a surface code to run 'below threshold', so that a bigger code means fewer logical errors.
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 23. 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 23.
Explainer · Fermilab
Fermilab
A short episode from Fermilab's Quantum Physics series with Don Lincoln and colleagues. Watch it alongside Chapter 23.
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 · Nobel Prize
Nobel Prize · John Clarke · 2025
"From SLUGs to macroscopic quantum phenomena": John Clarke on the 1984–85 Berkeley experiments in which an entire superconducting circuit, big enough to hold in your hand, tunnelled out of a trapped state as a single quantum object.
Lecture · Nobel Prize
Nobel Prize · Michel H. Devoret · 2025
"From macroscopic quantum phenomena to artificial atoms": Michel Devoret on how a circuit's quantized energy levels — measured in the same experiments — became the foundation of today's superconducting qubits.
