Choi, Kyung Soo (2011) Coherent charge of entanglement with atomic ensembles. Dissertation (Ph.D.), California Institute of Technology. resolver.caltech.edu/CaltechTHESIS:05192011-130117986


Quantum systems contain quantum nodes which coherently interact by means of quantum channels. They provide effective abilities for quantum computation, communication, and metrology. A regular reliance on these realizations may be the capability to create and store quantum states among multiple quantum nodes, and to disseminate these sources using the network using the quantum channels. During this thesis, I describe numerous experiments whereby single excitations in atomic ensembles are strongly coupled to optical modes and provide efficient method of the coherent charge of entangled states between matter and lightweight-weight. While using seminal proposal by Duan et al. we’ve generated measurement-caused entanglement in the excitation between two cold atomic ensembles. Employing this system, we investigated the text for the global bipartite entanglement and native correlations inside the subsystems. In addition, we achieved functional quantum nodes for entanglement distribution. Two pairs of remote ensembles at two quantum nodes were prepared into entangled states within the heralded and asynchronous fashion using the conditional controls within the entanglement. The quantum states within the ensembles were then distributed into polarization entangled states of photons. We prepared an similar quantum condition and transferred the nonlocal coherence between two pairs of heralded entangled atomic ensembles, supplying a stride towards entanglement connection.

Beyond such probabilistic approaches, we proven an assessment where entanglement between two quantum remembrances is produced using the reversible and deterministic mapping in the entangled condition regarding via dynamic electromagnetically caused transparency. This experiment opens novel prospects of integrating hybrid quantum systems by means of reversible quantum interfaces between light and matter. Then, we extended our make an effort to multipartite quantum systems. We theoretically investigated the portrayal of multipartite mode-entangled states by means of quantum uncertainty relations, and introduced theoretical tools to be sure the entanglement orders in multipartite systems. Particularly, we achieved entanglement to begin with delocalized photon among multiple optical modes (N 2). Finally, we’ve achieved measurement-caused entanglement of spin waves among four quantum remembrances. The person atomic components for the entangled W symptom in the 4 ensembles werethen coherently altered into four propagating entangled beams regarding via superradiant emissions. We observed the record and dynamic transitions for the multipartite entangled spin waves. Experiments described during this thesis therefore represent significant advances of experimental and theoretical abilities to create, store, transfer, and characterize entanglement of matter and lightweight-weight over quantum systems.
