Dec 14, 2021 · Quantum entanglement is a perplexing, scientific phenomenon. Two particles in quantum mechanics are said to be entangled when the particles are connected in such a way that they are not independent of one another. Below is a further exploration of this process and how scientists are working to understand more about it.
Jan 13, 2016 · The entanglement of two quantum objects means that measurements on one of the objects instantaneously determine the properties of the other one – without any exchange of information between them. Disapprovingly, Albert Einstein called this strange non-locality “spooky action at a distance”. In the meantime, physicists have warmed to it ...
这个时候，我们就可以看几个特点，一个是ergodicity，另一个就是子体系A的熵。那么在整个体系是纯态的时候，没有thermal的熵，就只有纠缠熵(entanglement entropy)了。如果要和统计力学上的平衡态表现一致，纠缠熵就必须符合所谓的"volumn law"，和子体系的体积成正比。

Jan 11, 2023 · The World Economic Forum's Global Risks Report 2023 explores some of the most severe risks we may face over the next decade that include energy supply and food crisis, rising inflation, cyberattacks, failure to meet net-zero targets, weaponization of economic policy, weakening of human rights.
Jan 17, 2019 · The series was written ahead of the 2019 Annual Meeting of the World Economic Forum in Davos, which focuses on “Globalization 4.0”. In previous pieces, we looked at some winners and losers of economic globalization, the environmental aspect of globalization, cultural globalization and digital globalization. Now we look back at its history.
量子纠缠（quantum entanglement），或称量子缠结，是一种量子力学现象，是1935年由爱因斯坦、波多尔斯基和罗森提出的一种波，其量子态表达式：其中x1，x2分别代表了两个粒子的坐标，这样一个量子态的基本特征是在任何表象下，它都不可以写成两个子系统的量子态的直积的形式。
