Single-Qubit Gate Sequencing
Add gates onto the wire in order. Run steps through them one at a time so you can watch amplitudes and the Bloch vector change gate by gate.
Circuit
q0 : |0⟩
+
State after each step
|ψ⟩ = 1|0⟩ + 0|1⟩
P(0) = 1.000 · P(1) = 0.000
Add gates above, then press Run.
Order matters. X then H is not the same as H then X — most gates don't commute. Try reordering and watch the final state change.
