这是量子计算技术向传感技术的巧妙转化，让传感器在量子噪声干扰下也能捕捉微弱信号。团队表示， 这种测量仍处于实验室阶段，但为未来量子传感技术提供了新框架，既可与现有方法互补，也可能催生 全新的应用领域。正如原子钟曾彻底改变导航与电信，极端灵敏的量子增强传感器也可能开辟全新的产 业。 （文章来源：科技日报） 团队用钟表作比喻来解释他们的发现：只有时针的钟表能粗略读出分钟，但具体时刻不准；只有分针的 钟表能精确读分钟，却无法判断小时。同理，他们通过牺牲部分全局信息，将量子测量的精度集中在微 小变化上，实现了对粒子位置和动量的同时高精度测量。这种测量理念就是"模运算"。 团队利用先前为量子纠错计算机开发的技术，首次在实验中验证了这一策略。他们将囚禁离子制备 为"网格态"，即量子计算中用于纠错的特殊量子态，通过测量离子的微小振动，实现位置和动量的联合 测量，精度超过传统经典传感器的"标准量子极限"。 澳大利亚和英国科学家团队提出一种新方法，可以同时精确测量粒子的位置和动量，重塑了量子不确定 性，为未来超精密传感技术奠定了基础。新方法的应用领域包括导航、医学和天文学。相关研究成果发 表在最新一期《科学进展》杂志上。 海森 ...

Core Viewpoint - The integration of tourism associations in the Yangtze River Delta region aims to enhance regional coordination and development through cultural and tourism collaboration, breaking down administrative barriers and reconstructing transportation networks [1][2][3]. Group 1: Institutional Breakthroughs - The implementation of the "same city treatment" mechanism allows for cross-provincial tourism with mutual recognition of standards, data sharing, and regulatory interaction, facilitating innovative initiatives like the "high-speed rail tourism annual pass" [2]. - The "Shanghai-Disneyland-Suzhou Gardens-Hangzhou West Lake" tourism route is projected to see a 28% increase in visitor numbers in 2024, driving over 35% growth in surrounding consumption [2]. - The "High-Quality Integrated Development Cooperation Agreement for Inbound Tourism" set to launch in 2025 aims to optimize the 240-hour transit visa exemption policy, enhancing the appeal of the "Shanghai-Hangzhou-Suzhou" tourism products [2]. Group 2: Regional Planning - The Shanghai metropolitan area is actively developing land-based tourism circle plans, with Jiangsu focusing on upgrading scenic spots and vacation areas, while Zhejiang emphasizes "transportation and tourism integration" [3]. - Anhui is promoting cultural tourism integration, embedding "Hui culture" into the broader Yangtze River Delta market [3]. Group 3: Practical Innovations - Brand collaboration is driving regional tourism consumption, with events like the Shanghai Tourism Festival and Jiangsu Rural Tourism Festival creating a celebratory matrix across the four regions [4]. - The "Four Seasons Anhui" promotional campaign is creating a tourism loop by integrating high-quality resources from Anhui with Shanghai [4]. - The high-speed rail network, exceeding 6,500 kilometers, facilitates a "1-hour metropolitan area, 3-hour city group, and 5-hour regional travel" model [4]. Group 4: Resource Integration - The Yangtze River Delta has established a competitive tourism product system based on seven core resources, creating 30 unique tourism routes and 8 world-class corridors [5]. - The launch of the "Shanghai Holiday Train: Enjoy the Yangtze River Delta" tourism train connects top attractions, transitioning regional tourism from "point supply" to "chain operation" [5]. Group 5: Value Co-Creation - The region is moving from "platter-style integration" to "systematic coupling" of cultural resources, enhancing cultural identity and value recognition [6][7]. - Collaborative projects, such as exhibitions and product development between cultural institutions, exemplify the trend of cultural integration [7]. - Future initiatives may include joint applications for intangible cultural heritage projects and shared performance resources to deepen cultural collaboration [7].
