Circuit Composer

Graphical quantum programming

What is it?

Circuit Composer is a graphical quantum programming tool that lets you drag and drop instructions to build quantum circuits and run them on real quantum hardware.

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 a density matrix or amplitude / probability histograms.

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 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.
