Quantum circuit composer · Qiskit-class.
Real state-vector simulation up to 8 qubits (256 amplitudes). Full Qiskit gate set: H · X · Y · Z · S · S† · T · T† · Rx · Ry · Rz · U3 · CX · CZ · CCX (Toffoli) · CSWAP (Fredkin) · SWAP · Measure. Paste any Qiskit-output QASM 2.0 and run it. Shot-based simulation with histogram. 100% browser, no cloud.
Gate palette · click then click a wire
For multi-qubit gates (CX/CZ/SWAP/etc): click control first, then target. Toffoli (CCX): two clicks for controls, third for target. Right-click any gate to delete.
