Abstract

Quantum information and communication is the next revolution in information technology. However, communication through quantum networks will require the ability to transmit, store, and interact with photonic quantum bits (qubits). The focus of this dissertation is a theoretical description of a promising technology for storage of photonic states employing electromagnetically induced transparency (EIT). A general semiclassical model for EIT photonic storage will be developed, a key capability required for understanding the effect of storage that is independent of the photonic state being stored. This dissertation demonstrates the capability of this model to predict light pulses retrieved from EIT storage as well as the ability to reshape the retrieved pulse or reconstruct the original pulse. Additionally, the exact quantum state produced by a parametric down conversion source is studied as a precursor to the derivation of a purely quantum model for EIT storage. This research lays the foundation for a comprehensive model for photonic storage, a vital component of future toolkits for quantum computation and quantum networks.
