BT UK Trial End-to-End Quantum-Secured Fibre Comms for 5G

By Mark Jackson

Telecoms giant BT (EE) and Cambridge spin-outNu-Quantum today claim to have launched a ?world-firsttrial? of end-to-end quantum-secured communications for the newgeneration of ultrafast 5G mobile(mobile broadband)networks, which is being called AIRQKD (Air Quantum Key Distribution).

Quantum secure links are often said to be virtually ?un-hackable? becausethey rely on the use of single particles of light (photons) to transmit specialdata encryption ?keys?(QKD ? Quantum Key Distribution). Should this communication be intercepted, thesender will be able to tell that the link has been tampered with and the stolenphotons cannot then be used as part of the key, thus rendering the data streamincomprehensible to a hacker.

Last month BT and Toshiba succeeded in establishingthe UK?s first ?industrialdeployment? of a quantum-secure network using Openreach?s?standard?fibre optic infrastructure (here). The key rate of the QKD system ran atjust 1.1Mbps (each encryption key has a length of 256 bits), while theencrypted data link itself was running at 10Gbps (it can go to several hundredgigabits and at distances of up to 120km).

Meanwhile the new trial, which will run for 36-months, is being funded by aninvestment of ?7.7m fromthe Quantum Technologies Challenge, led by UK Research and Innovation. BTclaims it will be the first to combine QKD over fixed fibre and free-spacenetworks (point-to-point laser connections between cell sites), withquantum-enhanced security chips in mobile devices.

Apparently, both will be used to deliver an ultra-secure linkbetween connected 5G towers and mobile devices, as well as to connected cars,in conjunction with the Warwick Manufacturing Group at Warwick University.

Professor Andrew Lord, BT?s Head of OpticalNetwork Research, said:

?The UK has firmly established itself as a global leader inquantum-based network security. With the AIRQKD trial, we?re delighted to betaking this to the next level and combining multiple quantum technologies frominnovative UK start-ups to build the world?s most secure fixed-mobilecommunications link. Connected cars are only one of the possible range ofapplications that will benefit from such ultra-secure connectivity in thefuture.?

Dr Carmen Palacios Berraquero, co-founderand CEO of Nu Quantum, said:

?In this project, we are basically creating the architecture for awhole new quantum-telecommunication industry, with a supply chain running fromcomponent manufacture through to end user. At Nu Quantum we have the uniqueability to use the smallest packets of light, making the most of quantummechanics and the security advantage it can give us. This 3-year partnershipwith BT and others across the UK is an important step taking quantum out of thelab and into our networks.?

The AIRQKD projectinvolves the following partners: BT, Lexden Technologies, OLC, Duality, BristolUniversity, Fraunhofer Centre for Applied Photonics, Strathclyde University,Warwick University Manufacturing Group, Bay Photonics, Heriot Watt University,Angoka, ArQit, Nu Quantum, National Physical Laboratory, CSA Catapult,Edinburgh University.

Industrial IoT connections to reach 37bn globally by 2025

Anasia D’mello

The researchidentified smart manufacturing as a key growth sector of the Industrial IoTmarket over the next five years; accounting for 22 billion connections by 2025.

The newresearch, Industrial IoT: Future MarketOutlook, Technology Analysis & Key Players 2020-2025,predicted that 5G and LPWA (Low Power Wide Area) networks will play pivotalroles in creating attractive service offerings to the manufacturing industry,and enabling the realisation of the ‘smart factory’ concept, in which real-timedata transmission and high connection densities allow highly-autonomousoperations for manufacturers.

5G to maximise benefits of smart factories

Thereport identified private 5G services as crucial to maximising the value of asmart factory to service users, by leveraging the technology to enable superiorlevels of autonomy amongst operations. It found that private 5G networks willprove most valuable when used for the transmission of large amounts of data inenvironments with a high density of connections, and where significant levelsof data are generated. In turn, this will enable large-scale manufacturers toreduce operational spend through efficiency gains.

Software revenue to dominate Industrial IoT market value

Theresearch forecasts that over 80% of global Industrial IoT market value will beattributable to software spend by 2025; reaching $216 billion (?184.34billion). Software tools leveraging machine learning for enhanced data analysisand the identification of network vulnerabilities are now essential toconnected manufacturing operations.

Researchauthor Scarlett Woodford noted: ‘Manufacturers must exercise caution whenimplementing IoT technology; resisting the temptation to introduce connectivityto all aspects of operations. Instead, manufacturers must focus on thecollection of data on the most valuable areas to drive efficiency gains.’

High pressure improves optical fibres

Using computer simulations, researchers at Hokkaido University, ThePennsylvania State University and their industry collaborators havetheoretically shown that signal loss from silica glass fibres can be reduced bymore than 50%, which could dramatically extend the distance data can betransmitted without the need for amplification.

?Improvements in silica glass, the most important material for opticalcommunication, have stalled in recent years due to lack of understanding of thematerial on the atomic level,? says Associate Professor Madoka Ono of HokkaidoUniversity?s Research Institute of Electronic Science (RIES). ?Our findings cannow help guide future physical experiments and production processes, though itwill be technically challenging.?

Ono and her collaborators used multiple computational methods to predictwhat happens to the atomic structure of silica glass under high temperature andhigh pressure. They found large voids between silica atoms form when the glassis heated up and then cooled down, which is called quenching, under lowpressure. But when this process occurs under 4 gigapascals (GPa), most of thelarge voids disappear and the glass takes on a much more uniform latticestructure.

Specifically, the models show that the glass goes under a physicaltransformation, and smaller rings of atoms are eliminated or ?pruned? allowinglarger rings to join more closely together. This helps to reduce the number oflarge voids and the average size of voids, which cause light scattering, anddecrease signal loss by more than 50 percent.

The researchers suspect even greater improvements can be achieved usinga slower cooling rate at higher pressure. The process could also be exploredfor other types of inorganic glass with similar structures. However, actuallymaking glass fibres under such high pressures at an industrial scale is verydifficult.

?Now that we know the ideal pressure, we hope this research will helpspur the development of high-pressure manufacturing devices that can producethis ultra-transparent silica glass,? Ono says.

Madoka Ono is part of theLaboratory of Nanostructured Functional Materials, RIES at Hokkaido University.Her research focuses on the properties of non-organic and silica glass by bothlaboratory experiments and computational analyses.
