Faculty at the University of Hannover have created two clouds of entangled atoms. Different from entangled atomic particles as earlier efforts created, the clouds of atoms were “Bose-Einstein condensates”. These atomic condensates were effectively occupying the same position in a coherent state; considered entangled. Separating the two clouds permitted the team to demonstrate the entangled quality. At present, large scale quantum computing is held back due to lack of needed scale in entangling particles. This could be a valuable step in the large scale quantum computing direction.
