Sam Samuel
Cisco, CTO for Mobility Business Group (MBG)

"Louis “Sam” Samuel joined Cisco in April 2013 and is currently a CTO for Mobility Business Group.  Since joining Cisco, Sam has had responsibility for 5G technology evolution, which covered a wide range of areas such as: virtualization and orchestration of its mobility products, autonomic management of cellular networks (via the application of SON technologies), policy and small cell technology evolution and the application of 5G to enterprises and verticals.  Sam is currently investigating, among others, the long-term effects of pandemics on technology accessibility.

Sam attended Queen Mary College, University of London, receiving an MEng in Communication Engineering in 1995 and a PhD in the Application of Non-Linear Dynamics to Teletraffic Modelling in 1999"


To scale quantum computers, the communication between them is key. The benefits of quantum computation are realized when that computation occurs in a distributed manner - this requires a quantum network to join those computational elements together, placing the prospect of quantum communication as a critical piece of the puzzle. However long-distance quantum communication is raising a number of questions that are not yet answered. There are different modes of operations that a quantum network could have, each of them requiring quantum repeaters to guarantee end-to-end communication. All these modes come with their challenges in terms of communication rate, quantum memory management or cost of the network. This leads to additional challenges to address such as the reliability of information exchange and the integrity of end-to-end transport, as well as considerations around the engineering approach to quantum networking. In this session, we will explore the role of quantum communication in getting quantum computers to scale meaningfully, the related challenges the industry needs to overcome and how Cisco is approaching these issues through close collaboration with selected academic partners.
