This week's fleet

The Provenova corpus holds 28 device snapshots drawn from six hardware providers this week: IBM contributes 17 snapshots, IQM and Origin Quantum three each, Quantinuum and IonQ two each, and Rigetti one. The most recent corpus refresh attempt ran on 2026-07-21. Rankings below come from two source classes, and the distinction governs how each should be read: vendor-reported specifications are manufacturer claims that Provenova does not independently verify, while Metriq submissions are community benchmark results published under CC-BY-4.0.

Two-qubit gate fidelity (vendor-reported). On the two-qubit fidelity board, Quantinuum's H2 ranks first at 0.999 across 56 qubits, captured 2026-07-03, and carries a vendor-reported Quantum Volume of 33,554,432 (2^25). IonQ's Forte follows at 0.996 (36 qubits, 36 algorithmic qubits) and IQM's Garnet at 0.9951 (20 qubits). Rigetti's Ankaa-3 reports 0.995 over 84 qubits, but its figure was captured on 2024-12-23 — the oldest data point in the group by more than eighteen months — so a strict ranking here compares devices measured at very different points in their calibration history. IonQ's Aria completes the five at 0.994 (25 qubits, 25 algorithmic qubits). Every entry on this board is vendor-reported, sourced from quantinuum.com, ionq.com, rigetti.com and the AWS Braket listing for Garnet, so all five values are best-case specifications rather than measured, redistributable results.

Error per layered gate (EPLG, Metriq). EPLG accumulates error per circuit layer, so lower is better. On the EPLG board, IBM's ibm_boston ranks first at 0.00154 (156 qubits, captured 2026-02-18), ahead of Quantinuum's h2-2 at 0.00180 (56 qubits, captured 2026-01-23). ibm_pittsburgh records 0.00273 and ibm_torino 0.00551 (133 qubits), with IQM's iqm_garnet fifth at 0.00823 (20 qubits). Every EPLG figure is a Metriq submission under CC-BY-4.0 and is redistributable.

Circuit layer operations per second (CLOPS, Metriq). CLOPS is a throughput measure where higher is better, and the CLOPS board is entirely IBM this week. ibm_fez records 368,905, followed by ibm_kingston at 362,372, ibm_boston at 360,574, ibm_pittsburgh at 358,613, ibm_marrakesh at 353,642 and ibm_torino at 345,670. All six are 156-qubit devices except ibm_torino at 133 qubits, and all are Metriq-sourced under CC-BY-4.0.

QAOA approximation ratio (Metriq). On the QAOA approximation-ratio board — higher is better — Quantinuum's h2-2 ranks first at 0.8018 (56 qubits), ahead of ibm_boston at 0.6734 and ibm_kingston at 0.6412. ibm_marrakesh (0.5731) and ibm_pittsburgh (0.5695) take the next two places, followed by ibm_torino (0.4560) and ibm_fez (0.4209). The tail is informative: iqm_garnet sits at 0.1432, IQM's iqm_emerald at 0.0099 (with a paired QFT accuracy of 0.1293, 54 qubits), and Origin's wukong_72 records a negative ratio of -0.0350 (72 qubits, captured 2026-02-24), meaning its sampled solutions fell below the classical random baseline on that instance. Where a Metriq submission also carries QFT accuracy, h2-2 records 0.967.

Movements

This is the third consecutive "State of Quantum Hardware" edition, and the standings on all four benchmark boards are unchanged from Week 29. The corpus holds the same 28 snapshots with the same provider breakdown as last week (IBM 17, IQM 3, Origin 3, Quantinuum 2, IonQ 2, Rigetti 1), and the two-qubit fidelity, EPLG, CLOPS and QAOA-ratio boards carry identical values and ordering to the Week 29 report. No captured-at date advanced on any board, so no device re-benchmarked into or out of a ranking this week. Quantinuum's H2 remains first on vendor-reported two-qubit fidelity (0.999) and h2-2 first on QAOA ratio (0.8018); IBM's ibm_boston still leads EPLG (0.00154) and ibm_fez still leads CLOPS (368,905).

The one substantive change is on the research side of the platform. The Week 29 report described a corpus of four research cards in total; the corpus-status endpoint now reports twelve cards in total, so eight cards have been published since that edition, including two dated within this week (see below). The only other platform change is operational: the most recent corpus refresh attempt is now dated 2026-07-21, versus 2026-07-15 for the prior edition, and it did not add or alter any device snapshot.

New on the platform

Two research cards were published during ISO week 30 (both dated 2026-07-23), against a daily publication cap of three cards:

• P=1 QAOA MaxCut ansatz on a triangle (K3), referencing arXiv:2607.20225 (added 2026-07-23).
• Coherent three-qubit quantum teleportation with deferred measurement, referencing arXiv:2607.19770 (added 2026-07-23).

Each card pairs a published circuit with its arXiv attribution and a deterministic simulator run. The research corpus now holds twelve cards in total; the eight added since Week 29 span state-preparation, teleportation, QFT, Grover-search, Bernstein–Vazirani and hardware-efficient-ansatz circuits, with the two above being the newest additions.

Method note

Provenova aggregates figures by source class, and every value above is tagged by its origin. Vendor-reported specifications (the two-qubit fidelity board) are manufacturer claims taken from provider material — quantinuum.com, ionq.com, rigetti.com and the AWS Braket listing — and are neither independently verified nor redistributable as raw data. Metriq submissions (the EPLG, CLOPS and QAOA-ratio boards) are community benchmarks published under CC-BY-4.0 and are redistributable. IBM device calibration enters the corpus under Apache-2.0. All platform algorithm runs behind the research cards are deterministic simulator executions rather than hardware executions, so a card's result reflects the compiled circuit, not a live device. Captured-at dates span a wide range — from 2024-12-23 for Ankaa-3 to 2026-07-03 for the vendor fidelity figures — and rankings should be read with that spread and each entry's source class in mind. Every number in this report was fetched from the Provenova leaderboard and corpus-status endpoints on 2026-07-25.
