Building a Roadmap for Quantum Communications
Andrew Shields, Head of Quantum Technology, Toshiba Europe Ltd

Quantum cryptography offers technologies for secure communications which will not be broken by more powerful computers in the future. Several trials have demonstrated promising applications in the government, financial, healthcare and industrial sectors.  In this talk, I will review the prospect of realizing global quantum networks, through the combination of long-range fibre and satellite links, as well as the integration of quantum and conventional signals.  Such progress will pave the way for a global quantum internet, which allows not only secure communications, but also networked quantum information processing.

The Impact of Quantum Technologies on Cyber Security
Jake Kennard, KETS Quantum Security

Driven by a promise of revolutionary computing capability, significant industrial investment has brought quantum computing to the cusp of being a commercial reality. While this will enable a wide array of applications, this capability will also undermine the basic secure fabric upon which our entire digital economy is built.

Here we will discuss the impact of quantum computing on internet security and what steps are being taken around the world to address this threat. Quantum Key Distribution uses the same technology as quantum computers to provide a level of security guaranteed by the laws of physics.  We will discuss the challenges that remain, how KETS and the community working to overcome them and the potential of a future quantum internet.

Application of Optical Atomic Clocks in a Timing Network
Lakshmi Rajagopal, Early Stage Researcher, BT Applied Research

According to the growing end user demands, time and frequency need to be distributed more precisely across the networks. The model is implemented to understand how time and frequency can be disseminated across a timing network. Conventional architecture and protocols used to deliver time and frequency is reaching its limits, as demands from the evolving networks raise to below sub-nanosecond levels. Proliferation of devices across the network is a challenge to distribute time through satellite technologies. The model aids to understand how time can be distributed across the network from highly precise optical atomic clocks. Applications requiring precise time emerge every day. With the model, it becomes easy to understand the flexibility of the architecture with time error requirements. Evaluating the impact of different types of asymmetries on time error, will lift the model to fit best with a practical scenario.

The engineering of a handheld QKD system
Andy Schreier, David Lowndes, John Rarity, Dominic O’Brien, University of Oxford

Quantum key distribution (QKD) enables two parties to exchange symmetrical keys with the unique ability to detect eavesdropper thanks to quantum mechanics. There is an increasing demand for improving security in mobile devices emphasising the need to expand QKD networks directly to the user. Handheld-based QKD systems that exchange keys using short-range optical links are one way of tackling this demand. However, such links require precise alignment between transmitter and receiver. In this presentation we outline the engineering challenges in achieving this.
