Strange quantum effect observed in unusually large object

Quantum entanglement. Conceptual artwork of a pair of entangled quantum particles or events (left and right) interacting at a distance. Quantum entanglement is one of the consequences of quantum theory. Two particles will appear to be linked across space and time, with changes to one of the particles (such as an observation or measurement) affecting the other one. This instantaneous effect appears to be independent of both space and time, meaning that, in the quantum realm, effect may precede cause. — An idea picture of a pair of entangled particles

A quantum property related to tiny objects has been discovered to persist in an experiment with greater than a thousand atoms. This might assist us perceive the place the boundary between the quantum world and the macroscopic world lies – if such a boundary exists.

The property for an object in query is two-fold: firstly, that its bodily traits depend upon whether or not it’s being measured and secondly, that it may be influenced over lengthy distances by one other object with out exchanging any recognized alerts. …
