MATTER-LIGHT ENTANGLEMENT WITH COLD ATOMIC ENSEMBLES

by Lan, Shau-Yu

In this thesis I present the investigations of matter-light entanglement in cold atomic samples. Particularly, entanglement of mixed species ensembles and bichromatic light fields is proposed and demonstrated experimentally. This approach avoids the use of two interferometrically separate paths for qubits entanglement distribution. I also present the first implementation of multiplexed quantum memory, and experimentally demonstrate entanglement involving arbitrary pairs of elements within this memory array. Finally, quantum interference of electromagnetic fields emitted by remote quantum memory elements separated by 5.5 m is realized.
