Standard Quantum Physics states that the outcome of measurements for some distant entangled subsystems is instantaneously statistically correlated, whatever their mutual distance. This correlation presents itself as if there were a correlation at a distance with infinite speed. It is expressed by the Bell Theorem and has been experimentally verified over distances up to 1200 km (Yin et al. [14]) with a time resolution of a few picoseconds, which can be translated into an apparent effective correlation speed larger than 107c.

The purpose of the present White Paper is to discuss the scientific interest and the feasibility to extend the correlation distance up to the Earth-Moon distance, i.e. \(2\times {10}^{4}\) times larger than in present experiments.

We are thus led to propose to install on the Moon a polarimeter and a high performance photon detector with a high temporal resolution.

Such an exploratory experiment would provide new tests of Quantum Physics and could perhaps discriminate between standard Quantum Physics and, for instance, the Bohmian theory.

地月距离处的量子相关性

标准量子物理学指出,不管它们相互之间的距离如何,某些遥远纠缠子系统的测量结果在统计上都是即时相关的。这种相关性呈现为自身,就好像在无限远的距离处存在相关性一样。它由贝尔定理表达,并已在长达1200 km的距离上进行了实验验证(Yin等人[14]),时间分辨率为几皮秒,可以转换为大于10 7的表观有效相关速度。C。

本白皮书的目的是讨论将相关距离扩展到地球-月球距离的科学兴趣和可行性,即将相关距离扩大到当前实验的\(2 \ x {10} ^ {4} \)倍。

因此,我们被提议提出在月球上安装一个偏振计和一个具有高时间分辨率的高性能光子探测器。

这样的探索性实验将为量子物理学提供新的测试,并可能区分标准的量子物理学和例如波姆理论。
