Gate Playground
A single qubit, a row of gate buttons. Click to apply H, X, Y, Z, S, T. Each gate transforms the state — watch the Bloch sphere, the amplitudes, and the probabilities update together.
Things to try:
- Apply H twice. Why does the qubit return to |0⟩?
- Apply X, then H. Where does the state land?
- Apply H, then Z, then H. That's the classical NOT — expressed in the "H basis."
- Apply S twice. What single gate is equivalent?
- Starting from |0⟩, can you reach |1⟩ without using X?
