What the current evidence supports

Human editorial judgment · 2026-08-20

Track; not yet

Why
Genuine, peer-reviewed (PRL 131, 150601) milestone anchoring China's independent photonic quantum-supremacy track and referenced whenever it is compared against superconducting/neutral-atom platforms, but the demonstrated advantage is contested by peer-reviewed classical-simulation work (Nature Physics 2024) and the underlying task (Gaussian boson sampling) has no known practical application — real-world relevance stays unproven even as the lineage (now Jiuzhang 4.0) keeps advancing.
Next
Re-probe on the next USTC photonic-GBS generation (post-Jiuzhang 4.0, already live) or on any fault-tolerant, error-corrected, or application-relevant photonic quantum milestone; monitor whether classical spoofing/simulation algorithms fully close the claimed advantage gap.
