The enhanced interactions and extended spin-coherence times are essential steps toward realizing quantum computing systems to solve some problems faster than conventional systems.

A new study shows that the tiny hairs of Saharan silver ants possess crucial adaptive features that allow the ants to regulate their body temperatures and survive the scorching hot conditions of their desert habitat.
