The ISS's New Device Will Make Atoms Colder Than the Vacuum of Space NASA's Atomic Fridge Will Make the ISS the Coldest Known Place in the Universe Researchers are creating a spot colder than the vacuum of space inside the International Space Station Researchers create a quantum entanglement between two physically separated ultra-cold atomic clouds A quantum entanglement between two physically separated ultra-cold atomic clouds

A quantum entanglement between two physically separated ultra-cold atomic clouds

Karsten Lange et al, Entanglement between two spatially separated atomic modes, Science (2018). As Tóth explained, “Bose-Einstein condensates are achieved by cooling down the atoms to very low temperatures, close to absolute zero. Find out more. Unlike previous methods of quantum entanglement involving incoherent and thermal clouds of particles, in this experiment, the researchers used a cloud of atoms in the Bose-Einstein condensate state.
