Verified landmark results

Curated, peer-reviewed milestones — figures checked against the primary source and cited at the foot of the page.

2026

These very recent 2026 results are summarized here as reported; treat the exact figures as provisional and defer to the official publications and vendor announcements for the final numbers.

Jun 2026

Microsoft × Quantinuum — an 800× logical-vs-physical error gap, validated in Nature

Peer-reviewed results confirmed a roughly 800-fold reduction between physical and logical error rates on trapped-ion hardware (System Model H2, 56 fully connected qubits, quantum volume 225), encoding four logical qubits from thirty physical ions — the largest physical-to-logical gap independently validated to date.

May 2026

Origin Quantum (本源) — Wukong-180, a 180-qubit single-chip superconducting QPU

China's fourth-generation superconducting machine went live on Origin's cloud with 180 computational qubits plus 251 coupling qubits on a single self-developed chip, reporting 99.9% single-qubit, 99% two-qubit, and 99% readout fidelity.

Jan 2026

QuEra — 96 logical qubits from 448 neutral atoms

Using high-rate [[16,6,4]] codes operated below threshold, QuEra encoded 96 logical qubits from 448 physical atoms — the first demonstration of more than 48 verified logical qubits, roughly doubling the prior record and reported in Nature.

2025

Nov 2025

IBM — Nighthawk and Loon

Nighthawk packs 120 qubits on a square lattice with 218 next-generation tunable couplers, designed to run circuits of up to 5,000 two-qubit gates (roadmapped to 7,500 by the end of 2026 and 10,000 in 2027). Loon, an experimental processor, demonstrated the full set of components for fault tolerance — c-couplers reaching beyond nearest neighbours and a qLDPC-oriented architecture — on IBM's path to a fault-tolerant system (Starling) by 2029.

2025

IonQ — Tempo reaches #AQ 64

IonQ's Tempo trapped-ion system hit an algorithmic-qubit benchmark of #AQ 64 ahead of schedule, with on the order of 100 physical qubits.

2025

USTC — Zuchongzhi 3.0

A 105-qubit superconducting processor from USTC demonstrated a random-circuit-sampling quantum advantage — a significant result alongside the Jiuzhang photonic line.

2024

Dec 2024

Google — Willow and below-threshold error correction

On the 105-qubit Willow chip, Google showed that the logical error rate is suppressed by a factor of Λ ≈ 2.14 each time the surface-code distance grows by 2 (from 3 to 5 to 7) — error correction that improves with scale, published in Nature 638, 920 (2025).

The road ahead

Several major vendors have published roadmaps targeting fault-tolerant milestones around the early 2030s, but these remain roadmap targets, not guaranteed outcomes. A few anchored targets:

  • IBM — IBM's roadmap targets practical quantum advantage demonstrations in 2026, a logical-memory module (Kookaburra) around 2026, and a fault-tolerant system (Starling, ~200 logical qubits) by 2029.
  • IonQ — IonQ's roadmap targets a two-chip interconnected module with photonic networking (~20,000 physical qubits, on the order of 1,600 logical) by 2028.
  • Atom Computing × Microsoft — "Magne," a roadmap target of 50 logical qubits from ~1,200 physical atoms, expected around the start of 2027.

Want to migrate these examples to a vendor's real-hardware workflow? Real-hardware / cloud submission is a planned capability — the reference build accepts vendor target names but runs locally on the CPU statevector simulator. See Prepare Your First Vendor Hardware Workflow and the per-vendor Hands-On guides.

2024 年 12 月

谷歌——Willow 与阈值之下的纠错

在 105 比特的 Willow 芯片上，谷歌证明:表面码距离每增加 2（从 3 到 5 再到 7），逻辑错误率就被抑制约 Λ ≈ 2.14 倍——纠错能力随规模提升，成果发表于《自然》638, 920(2025)。

未来路线

多家主要厂商发布了面向 2030 年前后容错里程碑的路线图，但这些仍是路线图目标，而非确定结果。几个有明确锚点的目标:

  • IBM——IBM 路线图目标是在 2026 年展示实用量子优势相关能力，2026 年前后推出逻辑存储模块（Kookaburra），2029 年推出容错系统（Starling，约 200 个逻辑量子比特）。
  • IonQ——IonQ 路线图目标是在 2028 年前后实现带光子互联的双芯片模块（约 20,000 个物理量子比特、约 1,600 个逻辑量子比特）。
  • Atom Computing × 微软——「Magne」，路线图目标是用约 1,200 个物理原子编码 50 个逻辑量子比特，预计 2027 年初投入运行。
