Bloch Sphere

About the tool

The Bloch sphere is a representation of a qubit, the fundamental building block of quantum computers.

This interactive visualization allows you to explore the Bloch sphere and the qubit state vectors for different values of the φ and θ angles.

The tool renders the Bloch sphere using the projection commonly used in quantum computing and geometry books. In this projection, the YZ plane is fixed and stays in the plane of the screen, and when you "rotate" the sphere, the sphere is warped to give the illusion of a 3D rotation.
