Scientists have captured the first ever image of a phenomenon which Albert Einstein once described as spooky action at a distance.科学家捕捉到了史上首个阿尔伯特·爱因斯坦曾叙述为“远距离的幽灵不道德”的现象的图像。The photo shows a strong form of quantum entanglement, where two particles interact and share their physical states for an instant.这张照片展出了很强的一种量子纠结形式,两个粒子相互作用,瞬间分享它们的物理状态。It occurs no matter how great the distance between the particles is.无论粒子距离多近都可以经常出现量子纠结。The connection is known as Bell entanglement and underpins the field of quantum mechanics.这种联系被称作贝尔纠结,是量子力学的核心。


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院的保罗-安托万·莫罗说道这个图像“高雅地展出了大自然的基本属性”。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.他补足说道:“这个结果令人兴奋,可用作前进量子计算出来这一新兴领域,带给新型光学技术。


”Einstein described quantum mechanics as spooky because of the instantaneousness of the apparent remote interaction between two entangled particles.爱因斯坦说道量子力学很“可怕”,因为两个距离显著较远的纠结粒子瞬间就能相互作用。The interaction also seemed incompatible with elements of his special theory of relativity.这种相互作用样子也和他狭义相对论的元素互为对立。Scientist John Bell later formalised the concept by describing in detail a strong form of entanglement exhibiting the feature.后来科学家约翰·贝尔通过详细描述一个展现出出该特性的强劲纠结形式来使这一概念一般化。Bell entanglement is now harnessed in practical applications such as quantum computing and cryptography.贝尔纠结现在被用作多个实际应用于,如量子计算出来和密码学。

However, it has never before been captured in a single image.但此前它未曾被捕捉到单一图像。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.格拉斯哥大学的一个物理学家团队设计了一个系统,一串纠结光子从一个量子光源收到,穿越“非常规物体”。This was displayed on liquid-crystal materials which change the phase of the photons as they pass through.这通过液晶材料来展现出,在光子穿越时转变光子的振幅。
