The cold-atom approach involves using finely focused laser beams (the ‘optical tweezers’) to trap individual atoms in a two-dimensional grid held at temperatures close to absolute zero.

The Cold Atoms Lab (CAL) is a compact, atom chip-based facility for examining ultra-cold quantum gases such as Bose-Einstein condensates (BEC). CAL represents a new era in ISS research, as now, for ...

No date has yet been set for the Cold Atom Space Payload (Caspa) mission. It hopes to replicate lab experiments that have shown cold atoms can be used as "ultra-sensitive sensors" capable of ...
