Hydrogen atoms under the exact STO‑3G pair potential, solved by full CI in your browser rather than fetched, integrated symplectically, with every energy and momentum flow on a gated ledger.
Recursive quantum-to-bulk water observatory across 4 continuous scale bands: vacuum (~0.1 Å) to 1 km. Four live controls (Temperature, NPT Barostat, Timescale Governor, 1G Gravity), one reset control, a scene-scaled ledgered hand, blind phase classifier, and live Holon closure defect lens.
The QVM's record, in the tree rather than on this page: the Clifford tier ahead of stim on the preregistered bake-off at every size to 4,096 qubits (conformance/BENCHMARKS.md); a distance-221 surface code with full adaptive syndrome extraction at parity with stim (conformance/bigqvm/RESUME.md); and QVM-ACUITY-1, where the cheap Clifford sector is FOUND by a closure test, the hard part is PRICED before it runs, and only enough of it is done to reach the acuity asked, with a certificate that held on 450 of 450 runs (conformance/qasm/QVM_ACUITY1_RESULTS.md).
Unified split-screen interface: 2D/3D Molecular Physics viewport paired with Interactive Stratified QVM & ZX Spider Graph editor. Real-time Retract Bridge connects atoms and bonds directly to quantum FCI/MPS statevector amplitudes, spin sector ⟨S²⟩, and Holon Commuting Square telemetry (δ, κ, W*).
Canvas. About 115 KB of WebAssembly: the browser owns input and pixels, the wasm owns the physics.
Bevy. Orbit the box, drag an atom through the spring, watch the same ledger. Megabytes rather than kilobytes — it brings its own renderer.
