Build quantum circuits — transform qubits to match the target state
✕How to play: Select a gate from the palette below, then click on a cell in the circuit grid to place it.
Click a placed gate to remove it. Use H (Hadamard) to create superposition, X to flip bits,
CNOT to entangle qubits. Press Run Circuit to simulate and check if you match the target state!
