Quantum computing relies on some rather confounding phenomena from quantum mechanics. In the quantum world, particles can exist in a state of superposition, which means that they can be in multiple states at the same time. This series of videos explores the concept of superposition and how quantum computing seeks to exploit this principal for unprecedented gains in computing power.

Sculptures Disappear Into Thin Air

The sculptor Julian Voss-Andreae explores the concept of superposition by creating works that demonstrate a superposition of states. Can a sculpture be both visible and invisible?

Matthieu Robert Ortis's Wire Sculptor

Another sculptor, Matthieu Robert Ortis, creates wire sculptures that when viewed from different angles reveal shockingly different images. Watch as the sculpture in this video shifts from an image of two giraffes to an elephant - these two distinct images exist in a superposition!

Schrödinger's Cat

This short video demonstrates the concept of quantum superposition through the classic thought experiment of Schrödinger's Cat.

Quantum Superposition of States and Decoherence

Explore superposition through this short video demonstrating the superposition of states of an atom and the impact of measurement on those states.

Quantum Computing Principles with Music

In this video, the quantum computing principles of superposition and entanglement are explained by applying them to musical notation.

How Does a Quantum Computer Work?

This video explores superposition by introducing the concept of spin and comparing the inherent efficiencies and inefficiencies of classical and quantum computers.

Introduction to Superposition (MIT OpenCourseWare)

In this MIT lecture, a series of thought experiments involving "box apparatus" are used to illustrate the concepts of uncertainty and superposition, which are central to quantum mechanics.


This video discusses the difference between classical and quantum bits and introduces bra-ket notation, 2-qubit notation, and matrix notation of qubits in superposition.

The qubit

This video discusses the qubit, introduces ket notation, and the vector notation used to describe these quantum states.
