2026年6月17日,Ransford等人(Quantinuum与桑迪亚国家实验室)在《自然》发表了题为《A 98-qubit trapped-ion quantum computer with all-to-all connectivity》的同行评审论文(DOI: 10.1038/s41586-026-10676-4),并配有新闻与观点文章。这一成果确立了Helios是Quantinuum迄今最大、最可靠的量子计算机,并证明离子阱技术能在达到超导量子比特数量的同时,保持大幅更低的错误率。
门保真度
单量子比特门保真度:99.9975%(平均不保真度2.5×10⁻⁵)
两量子比特门保真度:99.921%(平均不保真度7.9×10⁻⁴)
状态制备与测量(SPAM)保真度:99.967%(平均不保真度3.3×10⁻⁴)
论文指出,这些不保真度都未达到根本极限,有望进一步提升。
QCCD架构、音叉型离子阱与全连接
Helios基于量子电荷耦合器件(QCCD)架构,采用二维表面电极阱。关键设计特点如下:
