Description of Activities:

Cold atomic ensembles are currently one of the most advanced systems for the quantum control of light matter interaction at the single excitation level. Single collective spin excitations (so called super atoms) can be created in a heralded fashion and efficiently transferred into a single photon field, thanks to a collective interference between all the emitters. Recent theoretical proposals have shown that the ability to precisely control the quantum state of single stored collective spin excitations would open new avenues for the realization of more efficient quantum repeater architectures. We investigate the quantum control of the inhomogeneous spin dephasing of super atoms in a laser cooled Rb atomic ensemble. This will enable the realization of a multi-qubit spin wave quantum memory.
