2025年诺贝尔物理学奖发得合理吗?
Hu Xiu· 2025-10-10 03:48
不过,业内一些讨论认为,今年诺奖似乎"发早了",因为实用超导量子计算机仍未落地;还有一些声音认为获奖人选不合理。本文作者将从 量子效应在宏观尺度的探索与发现,谈本次诺奖成就的意义并回答上述疑问。 本文来自微信公众号:返朴 (ID:fanpu2019),作者:无邪,头图来自:视觉中国 自量子力学诞生以来,关于量子世界与经典世界的边界在哪就一直是一个充满争议的问题。著名的"薛定谔的猫"思想实验,就是在思考这个 问题时提出来的。薛定谔的猫是一个比较极端的案例,它直接将量子力学的基本假定——波函数应用到日常生活可见可闻的宏观尺度,并得 出一个非常诡异的结论:在那个神秘的盒子里,有那么一只既死又活的猫!尽管物理上允许我们构造出一个测量,它的本征态是死猫与活猫 的叠加态,但现实世界似乎是存在禁忌的——我们只可能要么看到死猫,要么看到活猫。 很明显,将量子力学效应直接一步到位拉到宏观尺度会产生非常反直觉、违背常识的问题,所以接下来的问题是:如果我们确定量子力学无 法应用于我们日常可见的宏观尺度,那它到底在什么尺度上会失效呢?有这样一个明确的边界吗?有的话它在哪?如果没有,这中间又是如 何过渡的呢? 物理学家一直在追寻这些问 ...
专家解读诺贝尔物理学奖:三位获奖人为超导量子计算奠基

"量子系统是微观世界的规律,原子、分子都遵循量子力学的原理,但是能不能有看得见、摸得着的宏 观的量子效应,过去大家都不太清楚。"范桁说,1985年,John Clarke、Michel H. Devoret和John M. Martinis设计了一个超导器件,这个器件相对比较大,是肉眼可以看见的,在这种情况下很难有所谓的 量子效应,但他们在这个系统里观测到了量子效应,即他们首先在宏观可控的系统中发现了量子效应, 把量子器件从微观尺度突破到宏观尺度。" 新京报讯(记者张璐)北京时间10月7日下午5时45分,2025年诺贝尔物理学奖揭晓。美国科学家John Clarke、Michel H. Devoret和John M. Martinis获奖,以表彰他们"发现了电路中的宏观量子力学隧穿效应 和能量量子化"。中国科学院物理研究所研究员范桁、北京量子院执行院长常凯接受新京报记者采访, 对获奖人所做出的贡献进行解读。专家表示,三位获奖人为超导量子计算做了一系列奠基性工作。 10月7日,瑞典皇家科学院宣布,三名科学家因在量子力学领域的贡献获2025年诺贝尔物理学奖。新华 社记者 彭子洋 摄 "他们的发现为基于超导约瑟夫森 ...
