Textbook circuits — Bell, GHZ, QFT, Deutsch–Jozsa — built as 2ᴺ-amplitude statevectors and run on WebGPU compute shaders, each cross-checked against an f64 CPU reference. Live, in this tab.
Each circuit runs on the GPU and is verified against a Float64 CPU statevector — Δ is the max |pgpu − pcpu| over all basis states.
Random brick-wall circuit, swept over qubit count N. The CPU column is only populated for N ≤ 18 — beyond that the f64 reference is too slow to be worth it.
