(PhysOrg.com) -- In the development of quantum information processing, one of the key requirements is achieving quantum entanglement. But recently, physicists have been investigating other forms of quantum correlations besides entanglement, and wondering if they may be useful and if they may play a role in future quantum communication and computation. In a new study, scientists have found that other forms of quantum correlations can be used to obtain useful entanglement of macroscopic systems, providing new insight and potentially leading to novel quantum technologies.

In its infancy, when the universe was a few millionths of a second old, the elemental constituents of matter moved freely in a hot, dense soup of quarks and gluons. As the universe expanded, this quark–gluon plasma quickly cooled, and protons and neutrons and other forms of normal matter "froze out": the quarks became bound together by the exchange of gluons, the carriers of the color force.
