One idea per sim. Everything runs in your browser — no accounts, no installs, no telemetry, and no maths background assumed beyond a bit of trigonometry.
A single qubit on the Bloch sphere. Apply X, Y, Z, H, S, T and arbitrary rotations, watch the state vector travel the correct arc, and measure it up to ten thousand times to see the statistics converge.
Superposition · phase · interference · measurement
Bell states, the CNOT gate, and why correlated measurement outcomes are not the same thing as a hidden shared answer.
In progress
Build a small circuit gate by gate and read the state vector, the probability histogram and the equivalent matrix side by side.
