Quantum Studio for the desktop

Quantum Studio as an app. The interface is the browser's. The engine underneath is the quantum job service's engine (wai_quantum::engine), built natively: it uses every core, holds as much memory as the machine has, and works offline.

• Each job runs in a process of its own, this binary run as worker, so a large job cannot take the app's memory with it, and Cancel ends it.
• The worker plans and runs; the app seals. It signs the answer with this user's key, the command line's (~/.config/wai/quantum-key), which never leaves the app.
• Step through and editing by the drawing run natively here: the debugger steps a program and lists its branches off the window's thread, and a drawing's edits, its SVG and LaTeX, and its description in words answer at once.
• Saved jobs, programs and drawings go to ~/Documents/Quantum Studio/. wai-quantum verify checks a saved job.
• The job service is one switch away, as in the browser.
• Your own hardware: the providers you listed with wai-quantum providers add are under Your hardware. A run asks the provider for its estimate first and shows a dialog before one that is not free; the app reads the credential from the keychain and seals the counts with your key, and the page never sees the credential.
• Memory: a job may take $WAI_QUANTUM_MEMORY_GB (16 by default). The plan says when a job needs more.

What is stable

The app is an application. What it promises is the engine's, through what it saves: a job is the engine's job JSON, which follows its schemas, and its receipt verifies with wai-quantum verify in every later version. What each WAI Quantum version promises, and how a change is announced: the policy; what is deprecated: the deprecations.

Building

The app embeds the Studio's build, so build the Studio first:

(cd ../quantum-studio && npm ci && node build.mjs)
cargo build --locked --release             # add --features metal for the GPU state vector on macOS
./target/release/wai-quantum-desktop       # the app
./target/release/wai-quantum-desktop check # a job through the worker, sealed and verified, with no window

It draws with the operating system's own web view, so the app carries no browser of its own. Installers for macOS, Windows and Linux come from cargo tauri build.
