冷却原子 量子触点
2015/12/21
瑞士日内瓦大学和苏黎世联邦理工学院科学家合作，用量子冷却压缩的方法，将两种物质通过奇特的量子力学性质连接在一起。这一成果为深入理解量子物理学，制造出未来量子电路设备开辟了新途径。
欧盟时间测量技术持续改进
欧盟 时间测量技术
2015/12/17
地球自转一圈为一天24小时，1小时60分钟360秒，随时从我们身边悄悄溜走的时间决定着世界上的一切。时间如此重要，将花样年华变成暮暮老矣，从抚平心灵的创伤到回忆美好的时光。时间倒退到60年前的1955年，英国国家物理实验室（NPL）的研究人员发现，由于地球旋转的不规则，导致1秒时间长度的不一，为准确的天文观测提出严重的新问题。为此，NPL设计和研制出世界上第一座铯（Caesium）原子钟，奠定了目...
混合方案可使量子态隐形传输更有效
量子态 传输
2015/10/9
在过去的20年里，不借助物理传输将量子结构从一个地方转移到另一个地方的量子隐形传输，正从星际迷航般的幻想变为现实。在最新一期《自然·光子学》杂志上，由美日加三国科学家组成的国际团队则指出，基于不同协议和底层结构的混合方案或是量子态隐形传输的最有效方法。

Consider the pendulum of a grandfather clock. If you forget to wind it, you will eventually find the pendulum at rest, unmoving. However, this simple observation is only valid at the level of classica...
德国研制出地球上最弱磁场（图）
德国 地球 最弱磁场
2015/8/17
“最弱”这个词很少会让人欢呼雀跃，但今年夏天在太阳系最弱磁场空间（如图）中进行的实验却让科学家激动万分。由德国慕尼黑理工大学物理学家构建的这个最弱磁场比此前已知的最弱磁场空间“弱”了10倍，使该空间的磁场引力甚至低于星际之间几乎虚无的引力。
