Qubits
1 / 5Changing the qubit count re-initialises every qubit to |0⟩.
Single-qubit gates
Applied to target q0.
Rotations
θ = π/2rad
Multi-qubit gates
Add a second qubit to use entangling gates.
Preset experiments

Measurement
Sampling runs repeated measurements on copies (state unchanged). "Measure qN" performs one projective measurement and collapses the live state.
