QAtlas curated demonstration
Plus vs Minus
Same basis probabilities; the sculpture’s phase ticks and hue distinguish the states.
What this demonstration shows
The |+⟩ and |−⟩ states assign the same probability to each computational-basis outcome, yet their relative phase differs by π. The paired view makes that distinction inspectable without changing the branch populations.
How to inspect it
Compare phase marks first, then confirm that the probability readout remains equal. This is a phase comparison, not an entanglement demonstration.
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.
OpenQASM 2.0 subset
Accepts qreg/creg, X/Y/Z/H/S/T/RX/RY/RZ/CNOT/CZ/SWAP, barriers, and terminal measurements only.
Timeline & measurement
Every gate produces an exact stored state. Discrete gates use a labelled visual transition; rotations can be interpreted as intermediate unitaries.
