⚙ Under the hood

A 2D quantum circuit builder for up to 3 qubits. Place H, X, Y, Z, S, T, CNOT and SWAP gates on a click-to-place circuit diagram and watch the real 8-dimensional complex state vector update through genuine gate-matrix multiplication. Measurement probabilities are computed live as |amplitude|² for each of the 8 basis states, with Bell, GHZ and 2-qubit Grover presets included.
