BT Presents at Networking Field Day 37



Networking Field Day 37


This Presentation date is March 19, 2025 at 9:00-10:30.

Presenters: Andrew Lord

The Quantum Revolution and its Impact on Telecommunications

Quantum computing and communications are set to revolutionise technology, offering unprecedented
processing power and secure data transmission. This presentation explores the key aspects of quantum
technology, starting with an introduction to quantum mechanics and why it holds such transformational
potential. Exploring what quantum computers can achieve, from solving complex problems to enhancing AI
and material design, and how quantum communications could redefine data security.
Security is a major focus, as quantum computers pose a threat to current cryptographic systems. Andrew
Lord will cover how Post-Quantum Cryptography (PQC) and Quantum Key Distribution (QKD) are being
developed to safeguard sensitive data.
How close are we to a quantum breakthrough? Andrew assesses the current state of quantum technology,
highlighting BT’s contributions, and mapping out realistic expectations for the next 10–15 years.
Finally, Andrew will provide an honest evaluation of the risks, market pressures, and evolving quantum
ecosystem, giving you a clear picture of the opportunities and challenges ahead.

Presenter: Andrew Lord, FIEEE and BT Fellow Senior Manager, Optics and Quantum Centre of Excellence, BT Group
