A gate given whole registers applies to each index (`h q;`, `cx a, b;` over registers of one length). +- The standard gates, with OpenQASM 3's definitions: {}. +- Angles: numbers, `pi`, `tau` and `euler`, with `+ - * / ^` and `sin cos tan exp ln sqrt arcsin arccos arctan`. +- `gate` definitions, with parameters; each call is inlined. `barrier` is read and has no effect. +- Control modifiers: `ctrl @`, `ctrl(n) @`, `negctrl @` and `negctrl(n) @`, on {}. +- Measurement in every form: `c[0] = measure q[0];`, `c = measure q;`, `measure q -> c;`, `measure q;`, `bit b = measure q;`. With no measurement at all, every qubit is measured into the bit of its own index. +- `reset`, anywhere. +- Classical control on measured bits: `if (c[0])`, `if (!c[0])`, `if (c == 3)` and `if (c != 3)`, with a `{{ block }}` or one statement, and `else`; and OpenQASM 2's `if(c==3) x q;`. +- Generators: `input int n;` and `input uint n;` take a whole number given when the program is read; `const int k = …;` names one; `for i in [a:b] {{ … }}` (also `[a:step:b]`, both ends included, and `{{a, b, c}}`) is unrolled once per value. Indices and sizes take integer arithmetic (`q[2 * i + 1]`, `qubit[n + 1] q;`). One program so describes a family of circuits. The command line takes the values with `--input n=5`, and the local MCP server with `\"inputs\": {{\"n\": 5}}`; the job service reads one circuit, so send it a generator written out (`wai-quantum instance gen.qasm --input n=5`). + +## Refused, each with its line + +{}, the `inv @` and `pow @` modifiers, declarations inside `if`, `input` types other than `int` and `uint`, and anything not listed above.

Noise and amplitudes are refused for such a program. + +## Conventions + +- Counts are keyed by the program's classical bits, the highest bit first. +- Amplitudes take bit strings with one character per qubit, qubit n−1 first. +- Pauli observables name qubits from 0: `Z0 Z1`, `0.5 X2`, `X2 Y3`. +- Noise channels, each a probability: {}. + +## Limits + +- At most {} qubits declared and {} gates once expanded; at most {} shots, {} observables and {} amplitudes a job. +- Whole numbers in a request are within ±(2^53 − 1), so that every JSON reader reads them alike and the receipt binds them. +- Each method's reach in a job's memory, and its accuracy class: the methods resource ({METHODS}). + +## Where a program runs + +- On this machine: `wai-quantum run`, or the local MCP server (`wai-quantum mcp`).

A thorough search, with a contraction tree, runs locally: wai-quantum shortcuts --thorough. + +Parameters: +- `qasm` (string, required) + +### `quantum_service_info`: What the quantum service can do + +The methods with their qubit limits and what each answers, the accuracy classes, the per-client limits, the current load, and the conventions (bit order, Pauli strings). + +### `quantum_circuit_examples`: Ready-to-run quantum examples + +Worked examples, each a complete job (OpenQASM program and arguments) with what it shows: a Bell pair, a rotation, QAOA, noise, a 1000-qubit GHZ state, 100-qubit dynamics, 200 qubits as a matrix product state. Pass an example's job to run_quantum_circuit as it is, or adapt it. + +## Resources, on both servers + +### `wai-quantum://docs/language`: the OpenQASM the engine reads + + +Every surface (the command line and its MCP server, the job service and its MCP server, the browser Studio, the desktop app) reads a program with one reader, so a program means the same on each. + +#### Read + +- `OPENQASM 3.0;` or `OPENQASM 2.0;`, and `include` lines: the standard gate libraries are built in. +- Registers: `qubit[n] q;`, `qubit q;`, `qreg q[n];`, `bit[n] c;`, `creg c[n];`. A gate given whole registers applies to each index (`h q;`, `cx a, b;` over registers of one length). +- The standard gates, with OpenQASM 3's definitions: id x y z h s sdg t tdg sx sxdg rx ry rz p phase u1 u2 u u3 U cx CX cnot cy cz ch cp cphase cu1 crx cry crz cu cu3 swap iswap rxx ryy rzz ccx toffoli ccz cswap fredkin. +- Angles: numbers, `pi`, `tau` and `euler`, with `+ - * / ^` and `sin cos tan exp ln sqrt arcsin arccos arctan`. +- `gate` definitions, with parameters; each call is inlined. `barrier` is read and has no effect. +- Control modifiers: `ctrl @`, `ctrl(n) @`, `negctrl @` and `negctrl(n) @`, on x y z h s sdg t tdg p cx cy cz ch cp ccx ccz. +- Measurement in every form: `c[0] = measure q[0];`, `c = measure q;`, `measure q -> c;`, `measure q;`, `bit b = measure q;`. With no measurement at all, every qubit is measured into the bit of its own index. +- `reset`, anywhere. +- Classical control on measured bits: `if (c[0])`, `if (!c[0])`, `if (c == 3)` and `if (c != 3)`, with a `{ block }` or one statement, and `else`; and OpenQASM 2's `if(c==3) x q;`. +- Generators: `input int n;` and `input uint n;` take a whole number given when the program is read; `const int k = …;` names one; `for i in [a:b] { … }` (also `[a:step:b]`, both ends included, and `{a, b, c}`) is unrolled once per value. Indices and sizes take integer arithmetic (`q[2 * i + 1]`, `qubit[n + 1] q;`). One program so describes a family of circuits. The command line takes the values with `--input n=5`, and the local MCP server with `"inputs": {"n": 5}`; the job service reads one circuit, so send it a generator written out (`wai-quantum instance gen.qasm --input n=5`). + +#### Refused, each with its line + +`while`, `def`, `defcal`, `cal`, `box`, `let`, `output`, `delay`, `gphase`, the `inv @` and `pow @` modifiers, declarations inside `if`, `input` types other than `int` and `uint`, and anything not listed above. A refused program is not run at all. The diagnostics resource (wai-quantum://docs/diagnostics) lists each refusal, what the reader says, and what to write instead. + +#### Programs that measure in the middle + +A program that measures a qubit and then acts on it, resets one after its first gate, or uses `if` runs on `statevector` or `stabilizer`. Its shots split at each measurement or reset as independent runs would; its expectation values are exact, the mixture over every branch, of the state before the final measurements. Noise and amplitudes are refused for such a program. + +#### Conventions + +- Counts are keyed by the program's classical bits, the highest bit first. +- Amplitudes take bit strings with one character per qubit, qubit n−1 first. +- Pauli observables name qubits from 0: `Z0 Z1`, `0.5 X2`, `X2 Y3`. +- Noise channels, each a probability: depolarizing_1q, depolarizing_2q, amplitude_damping, dephasing, readout. + +#### Limits + +- At most 65536 qubits declared and 2000000 gates once expanded; at most 1000000 shots, 256 observables and 64 amplitudes a job. +- Whole numbers in a request are within ±(2^53 − 1), so that every JSON reader reads them alike and the receipt binds them. +- Each method's reach in a job's memory, and its accuracy class: the methods resource (wai-quantum://docs/methods). + +#### Where a program runs + +- On this machine: `wai-quantum run`, or the local MCP server (`wai-quantum mcp`). Results are signed with the user's key and nothing leaves the machine. +- On the free job service, for a program too large for this machine: `wai-quantum submit`, `POST https://wai.transaction.science/quantum-jobs/v1/run`, or its MCP server at https://wai.transaction.science/quantum-jobs/mcp. No account and no key. +- auto picks, in order: with noise, density_matrix, stabilizer, then trajectories; for counts, stabilizer, exact, statevector, statevector_single, cutrank, mps; for expectation values only, stabilizer, exact, statevector, statevector_single, pauli, mps; for amplitudes only, exact, statevector, statevector_single, cutrank, tensor_network, mps. A method that cannot take the program is skipped, and the plan says why the one chosen was chosen. + +### `wai-quantum://docs/diagnostics`: the reader's diagnostics + +The reader's refusals as it gives them today.
