speed
Supported syntax and limits

Use direct gate calls with numeric angles or single-assignment numeric constants. No Python loops, functions, custom gates, conditionals, resets, noise channels, or training code. Upload .py, .qasm, or .txt, up to 128 KB. Circuits are limited to 15 qubits and 1,500 operations.

Qiskit: QuantumCircuit(N); h, x, y, z, s, sdg, t, tdg, rx, ry, rz, p, cx, cy, cz, swap, ccx, barrier, measure_all(). Cirq: LineQubit.range(N) or NamedQubit; Circuit and append; direct gates including H, X, Y, Z, S, T, rotations, CNOT, CY, CZ, SWAP, CCX, and final measure. OpenQASM 2: one qreg/creg, supported gates and final whole-register measurement.

All measurements must be at the end and cover all qubits in ascending order. Output bit strings use q[n−1] … q[0], with q0 on the right. Simulation runs in your browser.
