Squeezed states can enhance the sensitivity of a detector and the storage capability of quantum memory devices. Because these features improve with an increase in system size, researchers are exploring ways to produce squeezed states in large ensembles of atoms.
Spin decoherence is a fundamental obstacle in quantum computation and spintronics. Scientists show they can increase the lifetime of a localized spin in a diamond lattice up to 100 times by polarizing the surrounding spins on the lattice.

A specially prepared Bose-Einstein condensate would produce oppositely directed beams of entangled atoms, which could be used for investigations of entanglement and quantum information theory. In the past only beams of entangled photons have been produced.
