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.
Course · Caltech
John Preskill · 2021
The graduate course from the physicist who coined the terms "quantum supremacy" and "NISQ": density operators, measurement, channels, Bell inequalities, teleportation, circuits, Shor's factoring, Grover's search and quantum simulation. Advanced, and worth every minute.
Panel · World Science Festival
World Science Festival · Brian Greene with David Z. Albert, Sean Carroll, Sheldon Goldstein and Ruediger Schack · 2014
Physicists and philosophers of physics argue about what a measurement really is — Bohmian mechanics, many worlds and QBism side by side — with Brian Greene keeping score. Ideal companion to Chapter 22: every position is an interpretation, and all of them agree with experiment.
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.
Lecture · Nobel Prize
Nobel Prize · John M. Martinis · 2025
"Prehistoric Superconducting Qubits": John Martinis, who later led Google's quantum-hardware team, traces the line from the 1980s tunnelling experiments to the superconducting qubit.
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 · 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.

The Science Asylum
Nick Lucid of The Science Asylum takes superposition back to its roots in ordinary wave physics and strips away the mystical talk that usually surrounds it. As you watch, test what you hear against this session's central claim: a superposition is one perfectly definite state written as a sum, and whether a state counts as a superposition depends on which measurement you have in mind.
