Scientists have captured the first ever image of a phenomenon which Albert Einstein once described as spooky action at a distance.生物学家捕获了有史以来第一个阿尔伯特·牛顿曾描述为“长距离的鬼魂不负责任”的状况的图象。The photo shows a strong form of quantum entanglement, where two particles interact and share their physical states for an instant.这张相片展览了较强的一种量子科技纠结方式,2个粒子相互作用,一瞬间共享他们的物理学情况。It occurs no matter how great the distance between the particles is.不管粒子间距多近都能够经常会出现量子科技纠结。

The connection is known as Bell entanglement and underpins the field of quantum mechanics.这类联络称之为贝尔纠结,是物理学的关键。Paul-Antoine Moreau, of the University of Glasgows School of Physics and Astronomy, said the image was an elegant demonstration of a fundamental property of nature.格拉斯哥大学物理与天文学学校的韦德-安托万·戈罗说道这一图象“优雅地展览了自然界的基础特性”。

He added: Its an exciting result which could be used to advance the emerging field of quantum computing and lead to new types of imaging.他补充说道:“这一結果令人激动,可作为前行量子计算机出去这一新起行业,带来新式光学技术。”Einstein described quantum mechanics as spooky because of the instantaneousness of the apparent remote interaction between two entangled particles.牛顿说道物理学很“恐怖”,由于2个间距明显很远的纠结粒子一瞬间就能相互作用。The interaction also seemed incompatible with elements of his special theory of relativity.这类相互作用模样也和他狭义相对论的原素相互之间对立面。

Scientist John Bell later formalised the concept by describing in detail a strong form of entanglement exhibiting the feature.之后生物学家罗伯特·贝尔根据详细说明一个展示出出该特点的强悍纠结方式来使这一定义一般化。Bell entanglement is now harnessed in practical applications such as quantum computing and cryptography.贝尔纠结如今被作为好几个具体运用于,如量子计算机出去和密码算法。

However, it has never before been captured in a single image.但先前它不曾被捕获单一图象。The team of physicists from the University of Glasgow devised a system that fired a stream of entangled photons from a quantum source of light at non-conventional objects.格拉斯哥高校的一个科学家精英团队设计方案了一个系统软件,一串纠结光子美容从一个量子科技灯源接到,穿越重生“非传统物件”。This was displayed on liquid-crystal materials which change the phase of the photons as they pass through.这根据光学材料来展示出,在光子美容穿越重生时变化光子美容的震幅。
