Try one small change.

Try turning off CX. With H still on, the ideal readouts change from 00/11 to 00/01.

Two alternatives. One Bell pair.

(|00⟩ + |11⟩) / √2

CX uses q₀ as control. The 01 branch becomes 11: the ideal readouts are 00 or 11, each with 50% probability.

Made for the curious

Less guessing.
More discovering.

Start with a question, follow a short lesson and try the idea as a circuit. Change one thing. See what you learn.

Your next step, when you are ready

Start local.
Keep the possibilities open.

A simulator is enough to begin. When you need hardware, explore supported connections and bring your own provider access.

  1. 01

    Start with a circuit.

    Open a saved example. Inspect the gates, source and result at your own pace.

    Explore the Bell example
  2. 02

    Find the right connection.

    Check what a provider supports before connecting your account or planning a hardware run.

    Check provider support

Availability, supported operations and provider charges vary.

Where will you begin?

There is more than one way in.

Follow your curiosity.

Short lessons, small experiments and room to ask why.

Start learning

Under the surface

Go deeper
when you are ready.

Start with a question. Follow it into the code, the hardware, or the reasoning behind your next move.

01 Can I connect quantum hardware?

Begin with a simulator. Connect through supported providers when you need hardware, using your own access. Device availability, supported operations and provider charges vary.

Check provider support
02 Can I work with generated code?

Follow a visual circuit into Qiskit or OpenQASM. Inspect the source behind a public example before opening your own workspace.

Explore generated code
03 How does AI help me build?

Ask for a change, review the proposal and choose what to apply. Your circuit and the decision to start a run stay in your hands.
