Mapping a quantum state of light onto a long-lived atomic spin state: towards quantum memory
C. Schori, B. Julsgaard, J. L. Soerensen +1
We report an experiment on mapping a quantum state of light onto the ground state spin of an ensemble of Cs atoms with the life time of 2 milliseconds. Quantum memory for one of th…
