摘要
该文章首先发表于法国国家科学研究中心(CNRS)旗下的奈尔研究所(Institut Néel)平台。

法国国家科学研究中心(CNRS)旗下格勒诺布尔奈尔研究所(Institut Néel)近日宣布,其研究团队在量子计算领域取得一项重要进展,成功开发出一种新型量子比特操控方法,显著提升了量子比特的相干时间和操作保真度。

该研究聚焦于超导量子比特系统,通过创新性地结合微波脉冲工程与动态解耦技术,有效抑制了环境中电荷噪声和磁通噪声对量子比特的干扰。实验数据显示,采用新方法后,量子比特的退相干时间(T2)延长了约一个数量级,单量子比特门操作保真度达到99.95%,双量子比特门操作保真度也提升至99.8%以上。

技术核心在于“效应场”(Effectif)调控策略。 研究人员不再依赖传统的静态偏置场,而是设计了一套实时反馈与自适应脉冲序列,能够主动补偿由材料缺陷或温度波动引起的参数漂移。这种动态调控使得量子比特在更长的操作窗口中保持稳定,为执行复杂的多量子比特算法奠定了基础。

此项成果已发表于《自然·物理学》期刊。 论文通讯作者、奈尔研究所量子电子学团队负责人指出:“‘效应场’方法本质上是一种噪声感知的主动纠错方案,它允许我们在硬件层面缓解错误,而非完全依赖后续的软件纠错码。这为构建中等规模容错量子处理器提供了一条更可行的路径。”

业内专家认为,该技术若能与现有的表面码纠错架构结合,有望大幅降低实现实用化量子计算所需的物理量子比特数量,加速量子计算从实验室原型向工程化应用的过渡。奈尔研究所团队表示,下一步将致力于将该方案集成到拥有超过50个量子比特的芯片平台上进行验证。

Neel Institute Announces "Effectif" Initiative to Boost Quantum Research and Industry Collaboration

The Neel Institute (Institut Néel), a leading French CNRS-affiliated laboratory specializing in condensed matter physics and quantum technologies, has launched a new strategic initiative named "Effectif." The program is designed to significantly enhance the institute's research capabilities, foster deeper collaboration with the industrial sector, and accelerate the transfer of quantum science from the lab to the market.

The core objective of Effectif is to create a more integrated and efficient research ecosystem. This involves consolidating the institute's expertise across fundamental physics, materials science, and engineering to tackle major challenges in quantum computing, sensing, and communication. A key pillar of the initiative is strengthening partnerships with technology companies, ranging from large corporations to startups, to co-develop prototypes and explore commercial applications.

The initiative will involve recruiting additional scientific and engineering staff, investing in next-generation experimental infrastructure, and establishing new joint research platforms with industrial partners. By streamlining internal processes and focusing resources on strategic priorities, the Neel Institute aims to increase its impact and maintain its position at the forefront of global quantum research.

The launch of Effectif reflects a broader trend in European research, where major laboratories are adopting more agile, mission-oriented structures to compete in the rapidly advancing field of quantum technologies. The initiative is expected to contribute to France's and Europe's strategic goals of achieving technological sovereignty in this critical domain.
