GHZ vs W
Two distinct three-qubit correlation structures in the same computational convention.
What this demonstration shows
GHZ and W states distribute probability and correlation differently across three qubits. Keeping the same computational convention makes their distinct structures easier to compare without turning either state into a literal object.
How to inspect it
Compare the populated bitstrings, selected ribbons, and labelled entropy. The visual comparison is descriptive; it does not replace state-level analysis.
One excitation is shared across three qubits. Branch size shows probability; the phase marks and ribbons make the representation’s relationships inspectable.

Representation limitation. This sculpture is a deterministic explanatory encoding, not literal physical space. It is computational-basis dependent; visual similarity cannot establish state equivalence, entanglement, or operational fidelity.

Timeline & measurement
Every gate produces an exact stored state. Discrete gates use a labelled visual transition; rotations can be interpreted as intermediate unitaries.
