2D crystal of ultracold charged atoms is biggest ever created

More than 100 charged calcium atoms chilled to extremely low temperatures have been arranged into a two-dimensional crystal, which could be used for studying quantum materials or building quantum computations

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.
