Two-qubit gate quality (two_qubit_gate_fidelity)99.6 %vendor claim
Vendor claim
- Method
- page footnote: 'industry standard benchmarks'; gate type not named in the table
- Aggregation
- median (per op.), 'typical performance' snapshot
- Notes
- Rigetti's Jan 9, 2026 press release separately reported 'a median two-qubit gate fidelity of... 99.7% on our 9-qubit system' (Rigetti-operated 9Q system, not necessarily a customer Novera).

Two-qubit gate quality (two_qubit_gate_fidelity_third_party_demo (Quantum Machines))99.5 median / 99.86 peak (CZ, across 11 functioning qubit pairs) %vendor claim
Vendor claim
- Method
- not verified — source page blocked (HTTP 403); figures seen only in retrieved search-result snippets citing Quantum Machines' announcement of operating a Rigetti Novera with its OPX1000 control system
- Aggregation
- median and peak
- Notes
- Claim by Quantum Machines (control-system vendor partner), not Rigetti and not peer-reviewed. Same snippets reported 99.93% median 1Q fidelity and 95% readout fidelity across the QPU. Recorded with caveat because the source page could not be fetched this session.

Readout (readout_fidelity)not publicly disclosed
Not publicly disclosed — checked 2026-08-19
- Finding
- No public disclosure found. This is a recorded, dated finding — we do not substitute an estimate or borrow a figure from a sibling device.
- Sources queried
- rigetti.com/novera full page HTML (fetched), rigetti.com/what-we-build, Quantum Machines press release and blog (both HTTP 403)
- Notes
- Rigetti does not publish a readout fidelity for Novera on its product page. A Quantum Machines announcement (blocked, HTTP 403; search snippet only) claimed '95% readout fidelity across the full QPU' in its own control-system demo — see the QM fact above.
Native gate set (native_gate_set)not publicly disclosed
Not publicly disclosed — checked 2026-08-19
- Finding
- No public disclosure found. This is a recorded, dated finding — we do not substitute an estimate or borrow a figure from a sibling device.
- Sources queried
- rigetti.com/novera (fetched raw HTML), Rigetti Medium blog listing in search results, AWS/Azure docs (Novera is not a cloud device)
- Notes
- Product page describes architecture (tunable couplers mediating 'fast, 2-qubit operations') but names no native gate set; customers operate it with their own control systems. Partner demos have run CZ gates (Quantum Machines) — unverified snippet.
