In the present research, described in the January 20 online edition of Nature Physics, an unknown quantum state  of a photonic qubit is transferred into quantum memory via teleportation and is stored by two clusters of rubidium  atoms. Each cluster contains approximately one million atoms, collected by a magneto-optical trap. The  teleported photonic qubit can be stored in memory and read out up to eight microseconds (millionths of a second)  before the state is lost.
