意大利格兰萨索国家实验室研究团队在距地表1.4公里深的地下进行了一项为期62天的实验，旨在检验重力波动是否会破坏量子叠加态1。研究人员使用咖啡杯大小的高纯锗晶体探测器（配有铜和铅防护层）搜索了理论预测中由时空涨落产生的极弱辐射信号1。实验未发现任何预期的信号1。
这一发现驳斥了匈牙利理论物理学家卡罗利哈奇在20世纪60年代提出的经典模型1。哈奇模型预测微小的重力诱导时空涨落会逐渐摧毁量子叠加状态1。该研究由弗拉斯卡蒂国家实验室研究主任、FQxI成员Catalina Curceanu与实验负责人Kristian Piscicchia等人主导，已于2026年6月发表在《新物理学杂志》上1。这一结果将物理学家对重力与量子力学相互作用的理论限制在更紧凑的范围内1。
Researchers at Italy's Gran Sasso National Laboratory have conducted a deep underground experiment that challenges a classical theory about how gravity interacts with quantum mechanics.1 Over a 62-day period, scientists used a high-purity germanium detector to search for an extremely faint radiation signal that should have been produced by gravitational fluctuations in spacetime.1 The detector, roughly the size of a coffee cup and shielded by layers of copper and lead, found no evidence of the predicted signal.1
The experiment was designed to test the Károly Díosi model, a theory proposed by Hungarian theoretical physicist Károly Díosi in the 1960s suggesting that gravitational fluctuations would gradually disrupt quantum superposition states.1 The negative result contradicts this classical framework and constrains theoretical models of how gravity and quantum mechanics interact.1 Led by Kristian Piscicchia and involving researcher Catalina Curceanu of the Frascati National Laboratory, the study was published in the New Journal of Physics in June 2026.1
