Circuit Composer¶
Drag and drop to build, visualize, and run circuits – no coding required.
What is it?¶
Circuit Composer is a graphical quantum programming tool that lets you drag and drop operations to build quantum circuits and run them on real quantum hardware.
Create your first quantum circuit with this step-by-step tutorial, or go directly to Circuit Composer.

How to build circuits and visualize qubit states with Circuit Composer.¶
What can it do?
Visualize qubit states
See how changes to your circuit affect the state of qubits, shown as an interactive q-sphere, or histograms showing measurement probabilities or statevector simulations.
Run on quantum hardware
Run your circuits on real quantum hardware to understand the effects of device noise.
Automatically generate code
Instead of writing code by hand, automatically generate OpenQASM or Python code that behaves the same way as the circuit you created with Circuit Composer.

Teach and learn
with Circuit Composer
Build circuits the way they look in textbooks and run them on real hardware to learn firsthand how they behave.
