Totally Secure Communications – protected by Quantum Mechanics

July 26, 2016 10:30 - 11:30 am


Quantum Mechanics is the physics of the very small – it describes the behaviour of atoms, electrons and photons of light, a behaviour that can appear remarkable and strange. One of these peculiar properties, superposition, has recently been harnessed to develop secure communications systems, using a technique known as Quantum Key Distribution (QKD). This talk will explain how these new systems work and how they rely on Quantum Mechanics to make them secure. The talk will look at the explosion of research and development taking place around the world, describing how fantastic science is now being transformed into exciting business applications. It will explain BT’s role in transformation from science to applications, focusing on integration with standard telecommunications equipment and development of Use Cases with customers.  The talk will end with a look into the future, including entanglement-based communications and satellite QKD.

Andrew joined BT in 1985 after a BA in Physics from Oxford University. He has worked on a wide range of optical network systems and technologies, including long haul subsea and terrestrial DWDM networks. He currently heads BT’s optical core and access research. He regularly helps organise and speaks at optical communications conferences, and he will be the General Chair of the Optical Fiber Communications Conference (OFC) in 2017 in Los Angeles. He is an associate Editor of Journal of Optical Communications and Networking (JOCN), Visiting Professor at Essex University and Senior Member of the IEEE.
