Beating cyber criminals with quantum solutions

As hackers get more sophisticated in their cyber crime efforts we need to look to new technology to make our systems more secure, and potentially unhackable. So how can quantum physics help?

Quantum computer makes finding new physics more difficult

Physicists often work unusual hours. You will find them running experiments at 4am and 10pm. This is because, so long as the pertinent conditions inside a lab – such as temperature or light level – are…
Let’s take a look back through the past 12 months of quantum physics research. sharyn morrow/Flickr

Computing, uncertainty … quantum leaps and bounds of 2014

The past year has provided some of the most interesting developments in quantum mechanics to date. The field is more than 100 years old and has been tested to unimaginable precision, yet some of its most…

Quantum computing poised for new silicon revolution

A dramatic increase in the amount of time data can be stored on a single atom means silicon could once again play a vital role in the development of super-fast computers. The silicon chip revolutionised…

Quantum tech disappoints, but only because we don’t get it

Over the next five years, the UK government will spend £270m on supporting research in “quantum technology”. When budget announcements were made in 2013, provisions for offshore wind and shale gas extraction…

X-ray vision for road diggers: the next quantum leap?

Quantum mechanics has been hailed as the next big thing in technology. And quantum computers are a media favourite. But there is a little-known quantum technology that can peer beneath the earth, which…
Quantum computers are no longer a science fiction dream, thanks to the work of researchers such as Andrea Morello. UNSW/Peter Morris

Qubits and pieces: in pursuit of quantum computing

The Prime Minister’s Prizes for Science recognise excellence in science and science teaching. This year, we asked three prizewinners to reflect on their work and factors that influenced their careers…
The next big thing: is quantum computing close to being a commercial reality? Image from www.shutterstock.com

Quantum computers: coming to a store near you?

Mike Lazaridis, founder and former CEO of BlackBerry, may be forgiven for not having the foresight of recognising the threat that the iPhone and Android smartphones would pose to his business. However…
A world-first in qubits has brought quantum computers a step closer. ffejery

Computing 1-0-1: quantum information in an atom’s core

You’ve heard of quantum computers – they harness the power of atoms and molecules to perform memory and processing tasks; they exist in labs but are still a long way off in practical terms. But maybe they’re…
