Course Description

Overview

Explore the challenges and potential of quantum networking in this 33-minute lecture by Don Towsley from UMass - Amherst. Delve into elementary quantum concepts, including qubits, superposition, and measurement. Examine long-distance entanglement and quantum networks, focusing on repeaters and end-to-end entanglements. Analyze the challenges in performance and control of quantum entanglement networks, discussing state information and path diversity. Investigate grid network phases and rate dependence on probability. Compare routing entanglement flows with global versus local state information, and consider multi-flow routing. Conclude with open questions and future directions for quantum internet research, while celebrating Jean's retirement.
