# RQM Two Qubit Target Synthesis

> RQM Two Qubit Target Synthesis is a paid API for AI agents from jobs.rqmtechnologies.com, paid per call via x402, $0.5/call, status unknown (last checked 2026-09-15).

Synthesizes and verifies a bounded target-basis implementation for a supported two-qubit gate operation, optimizing for gate count or circuit depth under specified objectives.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability rqm-two-qubit-target-synthesis-9d211987 -d '<json body>'
```

Example prompt: Synthesize an iSWAP gate using the CX basis, prioritizing two-qubit gate count first then depth, with at most 3 two-qubit gates and exact phase context.

## When to prefer this

Use this endpoint when you need a formally verified, target-basis-specific two-qubit gate decomposition with explicit bounds on gate count and depth optimization objectives. Prefer this over generic transpilers when you require bounded synthesis with a choice of priority between two-qubit gate count and depth, and when the operation is one of the supported standard two-qubit gates (identity, cx, cz, swap, iswap).

## Known failure modes

- Requested gate not in supported set (identity, cx, cz, swap, iswap) — validation error
- Target basis gates not in supported set — validation error
- max_two_qubit_gates set to 0 when non-trivial synthesis is required — infeasible synthesis
- No valid implementation found within the bounded max_two_qubit_gates constraint — synthesis failure
- Invalid phase_radians outside [-2π, 2π] — schema validation error
- Malformed idempotency_key — request rejected
