Quantum cryptography for mobile phones

04.04.2014

Secure mobile communications underpin our society and through mobile phones, tablets and laptops we have become online consumers. The security of mobile transactions is obscure to most people but is absolutely essential if we are to stay protected from malicious online attacks, fraud and theft.

Currently available quantum cryptography technology is bulky, expensive and limited to fixed physical locations – often server rooms in a bank.

The team at Bristol has shown how it is possible to reduce these bulky and expensive resources so that a client requires only the integration of an optical chip into a mobile handset.

The scheme relies on the breakthrough protocol developed by CQP research fellow Dr Anthony Laing, and colleagues, which allows the robust exchange of quantum information through an unstable environment. The research is published in the latest issue of Physical Review Letters.

Dr Anthony Laing said: "With much attention currently focused on privacy and information security, people are looking to quantum cryptography as a solution since its security is guaranteed by the laws of physics.

Our work here shows that quantum cryptography need not be limited to large corporations, but could be made available to members of the general public. The next step is to take our scheme out of the lab and deploy it in a real communications network."

The system uses photons – single particles of light – as the information carrier and the scheme relies on the integrated quantum circuits developed at the University of Bristol.

These tiny microchips are crucial for the widespread adoption of secure quantum communications technologies and herald a new dawn for secure mobile banking, online commerce, and information exchange and could shortly lead to the production of the first 'NSA proof' mobile phone.

This work was supported by EPSRC, ERC, QUANTIP, PHORBITEC, and NSQI.

The Centre for Quantum Photonics is a pioneering research group in the area of Quantum Technologies, it has over 70 members and grant portfolio of greater than £20million. Having invented the integrated quantum photonic chip it has already made publically accessible and available online a real quantum computer 'quantum in the Cloud' for the purposes of educating those interested in future quantum computing technologies. http://www.bristol.ac.uk/physics/research/quantum/qcloud/

Im Focus: Energy-autonomous and wireless monitoring protects marine gearboxes

The IPH presents a solution at HANNOVER MESSE 2015 to make ship traffic more reliable while decreasing the maintenance costs at the same time. In cooperation with project partners, the research institute from Hannover, Germany, has developed a sensor system which continuously monitors the condition of the marine gearbox, thus preventing breakdowns. Special feature: the monitoring system works wirelessly and energy-autonomously. The required electrical power is generated where it is needed – directly at the sensor.

As well as cars need to be certified regularly (in Germany by the TÜV – Technical Inspection Association), ships need to be inspected – if the powertrain stops...

Im Focus: Atlantic Ocean overturning found to slow down already today

The Atlantic overturning is one of Earth’s most important heat transport systems, pumping warm water northwards and cold water southwards. Also known as the Gulf Stream system, it is responsible for the mild climate in northwestern Europe. 

Scientists now found evidence for a slowdown of the overturning – multiple lines of observation suggest that in recent decades, the current system has been...
