Entangled matter

Entanglement is considered as the most profound feature of quantum mechanics but has been recently demonstrated for material objects containing billions of atoms. Entangled states are extremely fragile and require ultimately quiet environment to survive. Nonetheless it turned out that two large objects can stay entangled for up to a millisecond. Such entangled state can be used for quantum information processing, for example, for quantum memory for light and quantum teleportation.
