That reaction produces atomic and subatomic products different from either of the original two particles.

这种反应会产生与参与反应的两种粒子完全不同的原子和亚原子产物。

But rhis is the first time a quantum walk has been performed with two particles and the implications are far-reaching.

但是这是第一次用两个完全相同的光子来完成量子游走，这个试验意义深远。

This isn't easy, as the entangled link between two particles is fragile - tamper with it too much, and the link can be fouled.

这并非易事，因为两个粒子间的纠缠态链接非常脆弱-影响因素有很多，链接也很容易被弄乱。

So, how could he know that the charge on the two particles was equal?

就是这两种粒子,电荷量是相等的？

PROFESSOR: And this is a question based on where we left off on Wednesday -- we were talking about Coulomb's force law to describe the interaction between two particles and good job, most of you got this correct.

教授：这是我们上次最后,留下的问题-我们讲到,描述粒子间相互作用的,库伦定律，很好,大部分人都做对了。

Entanglement is the process whereby two particles interact with each other, and then are separated.

FORBES: New Technique Could Pave the Way for Quantum Information Networks

So, instead of being a pure kaon and a pure anti-kaon, the two particles that go flying off are actually blends of each.

ECONOMIST: What��s the matter?

The idea is that when WIMPs crash into each other, they annihilate and produce two particles electrons and positrons which are much easier to detect than the WIMPs themselves.
