Quirking

What happens inside a quantum circuit?

An interactive quantum circuit simulator built on the ideas behind Quirk. Arrange gates, watch quantum states change, and learn through guided lessons and visual explanations.

What is Quirking?

Quirking is my modern rewrite of Quirk, Craig Gidney’s quantum circuit simulator. Build a circuit in the browser and see how each gate changes its state through probability displays, Bloch spheres, and amplitude views.

Guided lessons introduce the ideas step by step. For deeper exploration, a ZX-calculus view connects circuits to diagrams you can simplify interactively. Circuits can be shared through links, and an offline HTML export lets you keep experimenting without a connection.
