## What it is
Quirk is a drag-and-drop quantum circuit simulator that runs entirely in the browser, letting users build small quantum circuits and see state displays update in real time. It is a toy/educational tool supporting up to 16 qubits, with bookmarkable circuits and inline visualizations like Bloch spheres and chance displays.

## Use cases
- simulate small quantum circuits in a browser without installing anything
- learn quantum computing by experimenting with gates visually
- build and share Grover search or teleportation circuit demos via links
- inspect qubit states and amplitudes while editing a circuit
- teach quantum algorithms with real-time inline state displays
- export circuit JSON or a self-contained offline HTML copy

## When to choose
- you want zero-setup, interactive exploration of circuits up to 16 qubits
- you are learning or teaching quantum computing fundamentals
- you need shareable, bookmarkable circuit links or offline HTML exports

## When to avoid
- you need large-scale or high-performance simulation beyond 16 qubits
- you need scripted/programmatic circuit construction or noise models
- you need mid-circuit measurement with recoherence of measured qubits

## Facets
- artifact type: application
