Watch: from silver halide to Pauli exclusion
Record plays the story once from the start and saves exactly what the canvas draws, captions included, as a video file.
Compare: classical and quantum, side by side
Drag the divider. Each pair is drawn at the same density, from the project's own records.
Roll a tile: watch the exclusion hole open
Pauli and Random are sampled here, in your browser, in ordinary floating point: an illustration. The project's own rolls come from a 256-bit exact sampler, and "Atlas shots" replays the 24,576 measured on Moth's Atlas.
How it works
Film, classically
A sheet of film is gelatin holding silver halide crystals scattered at random. Light makes some developable; the developer turns them to silver; the fixer washes the rest away. Where crystals happened to clump, you see grain.
Film, quantum
Here a 16-qubit circuit (51 Givens rotations, 102 CNOTs) prepares five free fermions on a 4 × 4 tile. Measuring every qubit lays five crystals. Fermions obey Pauli exclusion, so the crystals repel. The circuit ran on Moth Atlas's tomography-api-v2 engine: six jobs, 24,576 shots.
Fixed, bit for bit
Stacked 29 layers deep, the shots coat a sheet at Tri-X's density, developed with atlas-film on cft-fp256's pinned arithmetic. Each print is a record: its rolls, its recipe and the digest of every bit.
