It is found that the entangled states of two-particle system can be divided into two kinds, coherence-preserving states and fragile entangled states.

结果表明：两粒子纠缠态可分为相干保持态和脆弱纠缠态。

Composed of light-absorbing, colloidal quantum dots linked to carbon-based fullerene nanoparticles, these tiny two-particle systems can convert light to electricity in a precisely controlled way.

The ALA analyzed particle pollution levels two ways: short-term particle pollution, or high spikes in the level of soot and other toxins in the air that last a few hours to a few weeks, and year-round particle pollution, or the annual average of particle pollution levels.

So physicists are eagerly seeking more, and two groups working at Fermilab, a particle-physics laboratory near Chicago, think they have found a candidate.
