Catalog Description:
Applying exotic quantum properties such as entanglement to every-day applications such as communication and computation reveals new dimensions of such applications. Quantum encoding and entanglement distribution provide means to establish fundamentally secure communication links for transfer of classical and quantum data. Generation, transmission and storage of quantum optical information are basic processes required to establish a quantum optical network. This course describes the physics behind these processes and overviews various implementation approaches. Technologies including quantum key distribution, quantum repeaters, quantum memories and quantum teleportation will be discussed and their engineering challenges will be evaluated.
