# Workbench specifications

Each specification says what a family of circuits must do, what a candidate may use, and what it costs. `wai-quantum discover` keeps an archive beside it of the cheapest verified generator of every kind.

| Specification | Task | What beats the reference |
|---|---|---|
| `ghz-line.json` | the GHZ state on a line of qubits | starting from the middle and spreading both ways halves the depth |
| `ghz-all.json` | the GHZ state with every pair connected | doubling the qubits that hold the state each layer brings the depth to about log₂ n |

Both start from `ghz-chain.qasm`, the plain chain of CX gates: depth n.

```sh runnable copy=. in=discover
wai-quantum discover new ghz-all.json           # the archive, seeded with the reference
wai-quantum discover search ghz-all.json        # the built-in, blind search
wai-quantum discover submit ghz-all.json mine.qasm --note "doubling layers"
wai-quantum discover show ghz-all.json          # what was spent, the best, the front
wai-quantum discover verify ghz-all.json        # every sealed verdict
```

An agent proposes through `wai-quantum mcp` (`discover_archive`, `discover_evaluate`, `discover_submit`), working on the same archive.
