Create your first quantum circuit ¶
You can use Circuit Composer to build and run a complete quantum circuit. For your “Hello world” circuit, you will create a Bell state .
The visualizations at the bottom of the page will automatically update to reflect simulated results as you add operations to your circuit. However, if you would like the option to run your circuit on real quantum hardware or a simulator, or if you wish to visualize more than four qubits, you will need to sign in to IBM Quantum by clicking the Sign in button in the upper right corner.
Note
To follow these steps while building the circuit in IBM Quantum Composer, use the Application switcher in the top left corner to select Quantum Composer, then click the Composer docs and tutorials icon. Under Getting Started, select Create your first circuit walkthrough.
Step 1. Open IBM Quantum Composer. ¶
To open Circuit Composer, click the Application switcher (
) in the upper left corner, and choose Quantum Composer.
You will see a set of horizontal lines, or wires, that resemble a ruled piece of paper. The top wires are the qubits, and the bottom wire is a classical register.
The Files panel is automatically opened. You can close it by clicking the Files icon
