A scientist involved in expanding quantum communication to a network of users, is continuing his work at the University of Bristol. The enhanced cyber security offered by quantum communication has been historically limited to two partner exchanges. Now, for the first time, scientists have connected multiple users simultaneously on a quantum encrypted network without using trusted nodes. Researchers from the Institute…
New Silicon Chip For Helping Build Quantum Computers And Securing Our Information
Researchers at the University of Bristol’s Quantum Engineering Technology Labs have demonstrated a new type of silicon chip that can help building and testing quantum computers and could find their way into your mobile phone to secure information. Scientific effort worldwide is focused on attempting to use silicon photonics to realise quantum technologies, such as super-secure communications,…
New Study Proposes Greater Sharing Of Data Between Farmers And Archaeologists
A Bristol-led study suggests that developments in precision farming could yield data of great use to archaeological research, and that archaeological data could be valuable for modern farming systems. In a paper published in the journal Archaeological and Anthropological Sciences, lead researcher Henry Webber, a PhD student in the Department of Archaeology and Anthropology, surveys the…
Future Smartwatches Could Sense Hand Movement Using Ultrasound Imaging
New research has shown future wearable devices, such as smartwatches, could use ultrasound imaging to sense hand gestures. The research team led by Professor Mike Fraser, Asier Marzo and Jess McIntosh from the Bristol Interaction Group (BIG) at the University of Bristol, together with University Hospitals Bristol NHS Foundation Trust (UH Bristol), presented their paper…
Rise of the Internet Has Reduced Voter Turnout
The internet has transformed the way in which voters access and receive political information. It has allowed politicians to directly communicate their message to voters, circumventing the mainstream media which would traditionally filter information. Writing in IZA World of Labor, Dr Heblich from the Department of Economics, presents research from a number of countries, comparing…
Shape-Changing Metamaterial Developed Using Kirigami Technique
Engineers from the University of Bristol have developed a new shape-changing metamaterial using Kirigami, which is the ancient Japanese art of cutting and folding paper to obtain 3D shapes. Metamaterials are a class of material engineered to produce properties that don’t occur naturally. Currently metamaterials are used to make artificial electromagnetic and vibration absorbers and…
How Will People Interact with Technology in the Future?
New research that discusses how people will interact with technology in the future will be presented this week at one of the world’s most important conferences on human-computer interfaces, ACM CHI 2016, in San Jose, USA [7-12 May]. A team of researchers led by Professor Mike Fraser and Dr Anne Roudaut from Bristol University’s Bristol…
Optical Material from Secrets of Mantis Shrimp
A study into how animals secretly communicate has led to the discovery of a new way to create a polarizer — an optical device widely used in cameras, DVD players and sunglasses. Mantis shrimp like to keep their conversations private, which is why they communicate using the polarization of light. These animals have evolved bright…
New Frontiers in Communication Systems
Data centres such as the ones used by Google and Facebook are the fundamental backbone for a range of services and applications including cloud and fog computing, big data, Internet of Things (IoT), social networking, weather forecasting, earthquake and tsunami prediction and cyber security. As such they are a hidden, yet integral part of modern…
Quantum Computing Is Coming – Are You Prepared for It?
Quantum computing will change lives, society and the economy and a working system is expected to be developed by 2020 according to a leading figure in the world of quantum computing, who will talk tomorrow Jan. 21, 2016 at the World Economic Forum (WEF) in Davos, Switzerland. Professor O’Brien, Director of the Centre for Quantum…
Squid Inspires Camouflaging Smart Materials
Researchers from the University of Bristol have shown it is possible to create artificial skin that can be transformed at the flick of a switch to mimic one of nature’s masters of camouflage, the squid. The research team, from the University’s Department of Engineering Mathematics, have designed a smart materials system, inspired by biological chromatophores,…
The Quantum Revolution Is a Step Closer
Theories show how computing devices that operate according to quantum mechanics can solve problems that conventional (classical) computers, including super computers, can never solve. These theories have been experimentally tested for small-scale quantum systems, but the world is waiting for the first definitive demonstration of a quantum device that beats a classical computer. Now, researchers…

Innovative Millimeter Wave Communications
Wireless data connections that exploit millimeter wave radio spectrum (30GHz to 300GHz) are expected to be used in worldwide 5G networks from 2020. The University of Bristol’s Communication Systems and Networks research group has partnered with Bristol start-up Blu Wireless Technology (BWT) to develop this technology and they will demonstrate their innovative work at the…
Integration Brings Quantum Computer a Step Closer
An international research group led by the University of Bristol has made an important advance towards a quantum computer by shrinking down key components and integrating them onto a silicon microchip. Scientists and engineers from an international collaboration led by Dr Mark Thompson from the University of Bristol have, for the first time, generated and…
