wai/quantum-studio is an editor for OpenQASM programs with three places to run them: this browser (the engine in WebAssembly, in a worker), this computer (the engine built natively, in the desktop app), and the job service. Each returns the same job, and the Studio shows it the same way and checks its receipt where it runs. The same request and seed give the same counts in every place.
- The editor highlights OpenQASM, completes the standard gates and the program's own registers, marks the engine's diagnostics on their lines, and draws the circuit and shows the plan as the program is typed. Ctrl/⌘+Enter runs; Escape cancels.
- A result shows its method and why, its accuracy class, counts, expectation values, amplitudes with probability and phase, and a receipt naming whose key signed it, checked on this device, which can be downloaded. The program and the history of runs are kept on the device; a link carries the program in its fragment.
- It takes the host's design tokens (tokens.css when it stands alone) and follows the light and dark schemes.
- test/studio.test.mjs runs it in a browser: lint, draw and plan; a run checked here; an error on its line; any angle; the service giving the counts run here, shot for shot; Ctrl+Enter; the program and the history surviving a reload; no sideways scroll at a phone's width.
wai/wai-quantum-desktop is the app: the Studio's build around the engine natively. Each job runs in a process of its own (the binary as `worker`), so Cancel ends it and a large one cannot take the app with it. The worker plans and runs, and the app seals the answer with this user's key, the command line's. Jobs and programs are saved under ~/Documents/Quantum Studio/. `check` runs a Bell pair through the worker, sealed and verified, with no window.
engine::job splits into plan_and_run and seal (run is both), for hosts that run a job away from their key. wai-quantum-cli gains a library target for its key module, shared with the app.
.github/workflows/wai-quantum-studio.yml builds the engine's browser package, builds the Studio and runs its test, and on macOS runs the app's tests, clippy and check.
