Wedbush称Quantinuum Helios创99.9995%逻辑保真度纪录为高信号里程碑，但系两天前旧闻的券商点评，无新增事实

Quantinuum's ( QNT ) announcement this week that it set a new industry-wide accuracy record with its Helios computer is a “high signal milestone” for the quantum computing firm, Wedbush Securities said. “We believe that crossing the ~1 error per 1M operations (99.9999%) threshold is likely the level needed to enable the first general purpose scientifically useful error-corrected work, alongside higher logical qubit counts,” Wedhush Securities analyst Matt Bryson wrote in a note to clients. “We view validated logical fidelity results as high signal milestones. The result is also a constructive read on trapped-ion technology (same approach as IONQ). The trade-off, of course, is that this method needs 37 physical qubits to form each reliable unit, while QNT's previous approach required only 10 physical qubits per reliable unit, so accuracy gains appear to, for now, still come at a cost in hardware scaling.” Quantinuum's Helios supercomputer achieved a world-record in error-correction, with 99.9995% logical fidelity. That rate means just five errors in a million operations and is 10 times lower than the company's own record, set just last month, and 100 times lower than the best published rate from all other hardware modalities. Shares of the quantum computing firm were little changed in premarket trading on Wednesday.
