"information in photons converted to quantum mechanical state, precisely stored, and after a certain time converted back into photons... rubidium atoms in a few mm sized glass cell heated to 100°C increasing vapor pressure... exposed atoms to 1 tesla magnetic field shifting atomic energy levels facilitating photon quantum storage using additional laser beam, enabling storage for 100 ns (goal to increase)... storage demonstrated using strongly attenuated laser pulses... future: store single photons"
