October 2017: Dr Marcello Ferrera - Beating the electronic speed limit with light

The heart of any smartphone, tablet or computer is an electronic chip. And that's the problem.

If you can imagine a single chip containing thousands of transistors the size of bacteria, that's what they were like in the 1970s. These days some chips contain billions of tiny semiconductor switches.

Over the decades, these chips have been getting faster and faster. But a speed limit is looming.

The electrons rushing through the copper connections can't go much quicker because they start clumping together instead of flowing freely.

If we want our devices to go even faster, we'll have to drop electrons in favour of photons. In other words, light.  Read more at http://www.bbc.co.uk/news/uk-scotland-41517202

June 2017: Professor Gerald Buller - A Light Approach to Cybercrime Prevention

Heriot-Watt, NICT, and NTT researchers demonstrate record breaking transmission distance for quantum digital signatures using installed optical fibre in a metropolitan network.

We take it for granted that the messages and emails we send are not tampered with. But just as a hand-written signature on a document gives some confidence that the document is genuine, digital messages also need to be signed to guarantee that they haven’t been forged or tampered with. 

Schemes for digitally signing messages exist, and are now so widely used that the European Union has granted digital signatures the same legal standing as their handwritten counterparts.  However, the security of the signing methods we commonly use is only computational. This means that it relies on the difficulty of performing certain calculations, such as factoring large numbers. That is, signed messages can be forged with enough computational effort, and there is no guarantee that this will not happen. If better algorithms for these calculations are discovered, then the security of the signature schemes we use is no longer guaranteed.

Quantum digital signatures offer a potential alternative which guarantee security not through computational complexity but instead through the fundamental laws of quantum mechanics.  Previous demonstrations of quantum digital signatures have operated over relatively short lengths of optical fibre in controlled laboratory environments, severely limiting the prospect of practical applications.

A collaboration between researchers at Heriot-Watt University (Edinburgh, UK), The National Institute of Information and Communications Technology (Koganei, Tokyo, Japan), and The Nippon Telegraph and Telephone Corporation (Atsugi, Kanagawa, Japan) has successfully demonstrated transmission of quantum digital signatures over an optical fibre attenuation equivalent to 134 km  – the longest transmission distance to date.  The demonstration, which employed a combination of a fixed length of 90 km of installed optical fibre in the Tokyo metropolitan optical fibre network and controlled attenuation to simulate additional fibre lengths, used a prototype commercial system to carry out the transmission of the signatures – highlighting the commercial potential of this approach.

It is hoped that this demonstration will lead to future deployment of quantum digital signatures within the UK Quantum Network as part of the UK Quantum Technology Hub for Quantum Communications Technologies.

February 2017: Dr Alessandro Fedrizzi - Heriot-Watt helps Route Monkey take quantum leap

Professor David Corne from the School of Mathematical and Computing Sciences, and Dr Alessandro Fedrizzi, from the School of Engineering and Physical Sciences, have been working with Livingston-based company Route Monkey to create innovative algorithms for the company’s transport and travel systems.

The team has now launched a project with NQIT to develop, test and commercialise quantum algorithms.

Quantum computers use the fundamental laws of nature to solve certain tasks faster than classical computers. In this collaboration with Route Monkey, we’re developing quantum-enhanced software for real-world applications.

Dr Alessandro Fedrizzi, Heriot-Watt University

Route Monkey’s optimisation solutions eliminate unnecessary mileage and improve vehicle utilisation, typically helping to reduce fleet costs by up to 20 per cent and substantially cutting carbon emissions. The algorithms are capable of making millions of calculations in a relatively short space of time, vastly improving on manual transport planning. Read more...

February 2017: Professor Robert Thomson - Colours of light revealed in time-stretch breakthrough 

Professor Robert Thomson and his team, working in collaboration with physicists and engineers at the Universities of Bath and Edinburgh, have massively increased the technique’s potential applications. The team has multiplexed its detection capability by over two orders of magnitude, using advanced multicore optical fibres, photonic lanterns and single-photon-sensitive detector arrays.

In many cases, the most useful form of light is as a series of optical pulses, rather than a continuous stream. Previously, measuring the colours of light that form these pulses often required bulky and expensive instruments. One approach  is to use a technique known as time-stretch spectroscopy, but this technique has, until now, had limited applications outside the lab. Read more...

November 2016: Dr Erik Gauger - Catching the Sun

New research led by Heriot-Watt is offering the prospect of cheap and efficient solar cells of a conformable type that could be worn on the body or even painted onto windows.

Sunlight is our most abundant source of renewable energy, and learning how best to harvest this radiation holds the key to meeting the world's future power needs.

For solar energy to become a viable alternative to fossil fuels, solar cells need to be both inexpensive to manufacture and efficient in terms of energy they collect. Now a Scottish-led team have taken a major step towards this goal by using quantum mechanics to design molecular solar cells to be more efficient. Read more...

April 2016: Anti counterfeit hologram could end manufacturers' nightmare

Researchers at Heriot-Watt are developing a tamper-proof hologram that could replace serial numbers and barcodes, reducing the trade in counterfeit goods.

Manufacturers of high value goods like electronics and aviation parts etch serial numbers into products, use bar codes or place polymer holographic stickers on the items to provide identification and traceability of products and to assure customers of quality. However, serial numbers and bar codes can be damaged and stickers are vulnerable to tampering and counterfeiting.  Read more...

March 2016: Making light work – new research to exploit light in manufacturing

Four projects that exploit light in innovative manufacturing processes and technologies have secured £2.7 million funding from the EPSRC.

Following on from 14 feasibility studies announced in 2014, these schemes, which have support from companies such as Rolls-Royce and Renishaw, have the potential to impact the aerospace, laser and precision engineering industries.

The projects are diverse and exciting in their aims. They range from producing ultra-thin films for use in electronics, to incorporating metallic nanoparticles into materials such as plastics that can act as sensors or anti-microbial surfaces, to using lasers to make crystals for thin-film lasers and using terahertz radiation to detect where materials are stressed.
