Beginner / Quirk circuit simulator

Qubits, Gates & Superposition

Explore quantum circuits with Quirk, a visual simulator that runs in your browser without an account.

  • Apply an X gate to switch a qubit from 0 to 1.
  • Try a Hadamard (H) gate and inspect the measurement probabilities.
  • Apply H twice and compare the result with your starting state.
Open Quirk

Next step / IBM Quantum Composer

Build an Entangled Circuit

Use IBM Quantum Composer to design circuits visually and explore how quantum gates work together. An IBM account may be required.

  • Create a circuit with two qubits.
  • Apply H to the first qubit, then a controlled-X (CNOT) gate from the first to the second.
  • Measure both qubits and compare the 00 and 11 outcomes.
Open Composer

Each lab page includes individual videos and summaries from iQafé YouTube, freely available to watch. External YouTube links and circuit tools open in a new tab. External tools may have separate account requirements or usage limits; their terms apply.
