每经记者｜张宝莲 每经编辑｜董兴生 5月26日，A股可控核聚变概念板块逆势大涨，涨幅居前。5月27日，板块热度不减。有观点认为，板块 遭到热炒与核能商业化推进加速有关。 可控核聚变一旦实现，人类的能源将"无限续杯"，但是这样的蓝图究竟离我们有多远，产业链上的这些 企业正在做什么？ 可控核聚变产业链已初具雏形 核聚变，作为自然界中恒星发光发热的基本原理，其能量释放巨大且几乎无放射性废物产生，理论上是 清洁、高效、可持续的理想能源。 可控核聚变原料为氚和氘，1升海水可提取0.035克氘，聚变释放能量相当于燃烧300升汽油，全球海水 氘的储存量可供人类使用上百亿年，远超化石能源。 全球范围内，聚变研究主要通过磁约束聚变和惯性约束聚变两种主要的技术路径。其中，磁约束聚变最 有代表性的项目有ITER（国际热核聚变实验堆计划），而惯性约束聚变的代表性项目则有美国的国家 点火装置(NIF)。中银证券指出，磁约束聚变能量约束时间长、技术成熟度高、工程可行性较强，是目 前实现聚变能开发的最有效途径。 这一聚变过程发生在极为严苛的实验环境中，需要通过严密的大科学装置，以确保聚变反应的正常运 行。基于磁约束原理的托卡马克装置逐步在 ...

报告共计：36页 《2025年全球量子计算用同轴电缆市场分析报告》指出，极低温同轴电缆是超导量子计算系统的核心元件，需满足极端低温下高保真信号传输、低热负载及 抗干扰等要求，材料从单一金属拓展至超导合金与复合结构。市场呈现显著分层：4K以下高端产品单价达3千美元，由国际厂商主导，国内企业如西部超导 通过材料国产化和工艺创新逐步突破技术壁垒，4K以上产品价格较低（1-2美元/m），国内已实现商业化。 技术层面，同轴电缆面临"布线墙"和制冷极限挑战，柔性化、光电复用和高密度集成是主要发展方向，如Delft Circuits的Cri/oFlex技术通过柔性设计降低热 负载，Bluefors的高密度柔性布线平台提升通道容量。市场需求与量子比特规模密切相关，以千比特量子计算机为例，实际需求约3100根电缆（价值约6792 万元），理想情况下可降至1100根（价值约2410万元），4K以下产品利润占主导，单根毛利800-1200美元，毛利率27%-40%。 竞争格局上，国际厂商如Delft Circuits、CryoCoax垄断高端市场，国内西部超导在NbTi和Nb₃Sn线材领域领先，但柔性线缆等创新结构仍需突破。未来， ...
