Imagine in 2025 that quantum computers, while relatively expensive, are reliable, hugely powerful and able to circumvent strong encryption up to 256 bits. How should business, government and civil society prepare for such a future?

These are just some of the questions and scenarios that Professor Jeremy O'Brien, Director of the Centre for Quantum Photonics at the University of Bristol, will be addressing when he talks today (Thursday, January 19) at the annual meeting of the World Economic Forum (WEF) in Davos, Switzerland.

Part of the European Research Council (ERC) Ideas Lab delegation, he will be addressing industrial and political leaders from across the world.

Professor O’Brien has been actively involved with the WEF over the past few years and recently took on the role of co-chair of the Global Future Council on Computing. Last year he presented a talk on working towards a quantum computer discussing the future of computing and how new fields of computer sciences are paving the way for the next digital revolution.

Quantum computing has the capability to unlock answers to some of humanity’s most pressing questions that are presently unsolvable with current computing technologies.

In 2014, the UK government invested over £270 million in the development of quantum technologies, ensuring that the UK becomes the epicentre of a technology revolution and Professor O'Brien has been leading the development of quantum computing using light in its quantum state – the photon- as the key ingredient.

Professor O'Brien said: "Within a decade, quantum computers will begin to outperform everyday computers, leading to potential breakthroughs in artificial intelligence, the discovery of new pharmaceuticals and beyond.

"The very fast computing power given by quantum computers has the potential to disrupt traditional businesses and challenge our cyber-security. Businesses need to be ready for a quantum future because it’s coming."

Quantum technologies offer ultra-secure communications, sensors of unprecedented precision and computers that are exponentially more powerful than any supercomputer for a given task. These technologies are destined to fundamentally change our lives and the first commercially available quantum devices are only now beginning to emerge.

As the holder of a prestigious Royal Academy of Engineering Chair in Quantum Engineering and an EPSRC RISE leader, Professor O'Brien has a ten year vision to engineer new quantum technologies that will inevitably disrupt todays ICT models, creating new businesses and valuable new markets.

He is currently developing ways to bring quantum computing into reality and the market to transform artificial intelligence, healthcare, energy, finance, cyber security and the internet. Using a photonic approach to manufacture a universal quantum computer in a silicon fab, exploiting silicon photonics developed for optical interconnects in the semiconductor industry.

The World Economic Forum (WEF) Annual Meeting of business and political leaders is taking place from this week in Davos, Switzerland.
