QuantIC was excited to be involved in “Photonics Meets Real World Applications”, a joint doctoral training careers workshop for the EPSRC CDTs in Photonic Integration & Advanced Data Storage, Applied Photonics, and Intelligent Sensing & Measurement last week in Glasgow. The event, was an opportunity for CDT students to foster collaboration with industry and academic partners to foster collaboration and also provided them insight into knowledge transfer practices and working in industry.
Dr Richard Middlemiss, one of QuantIC’s researchers, was invited to speak at the event where he shared his experience on Wee-g, from taking it out of the labs and closer to commercialisation by working at Kelvin Nanotechnology. He said, “At the workshop I gave a talk on my experiences of working on an R&D project I have been working on for the last 6 years – the development of a new type of sensor for imaging things underground (e.g. magma under volcanos). Recently I spent 9 months on secondment with a nanotechnology company – KNT. It was an interesting experience to see the contrast of how industry and academia approach the same problem.”
The event, which was attended by 60 PhD students from universities across Scotland and Belfast, also saw QuantIC industry partners such as M Squared Lasers, Compound Semiconductor Technologies, Leonardo and KNT speaking about careers in the different sectors, including quantum technologies, where photonics is expected to play a leading role.
QuantIC and University of Glasgow researcher Professor Robert Hadfield has been awarded a Royal Society Leverhulme Trust Senior Research Fellowship to support his pioneering work on superconducting detectors, the world’s most sensitive detectors for infrared light.
Professor Hadfield has developed some of the world’s most sensitive detectors for single light quanta – photons – and deployed these detectors in a range of important emerging applications, including quantum cryptography, atmospheric remote sensing and dose monitoring for laser cancer treatment. The Fellowship will enable him to spend the next year concentrating in furthering his research in this field.
In addition to the Fellowship, Professor Hadfield has also been awarded a visiting professorship at the Swedish Royal Institute of Technology in Stockholm under the Swedish Wallenberg Centre for Quantum Technology where he is developing links for research collaboration. He said, “I am delighted to have received these prestigious awards. This is a fantastic opportunity to explore new research avenues and strengthen our international links. I am looking forward to contributing strongly to the next phase of QuantIC and the UK National Quantum Technologies Programme.”

The Committee, which exists to ensure that government policy and decision-making are based on good scientific and engineering advice and evidence, were up in Glasgow last Thursday 28 June for a formal oral evidence session on the committee’s inquiry into quantum technologies. Quantum technologies have been selected by the Government as one of fourteen ‘core industrial challenges’ to be tackled and the inquiry was launched early 2018 by the House of Commons Science and Technology Committee to address the opportunities and challenges for quantum technologies.
Following a written submission from QuantIC to the House of Commons Science and Technology Committee, the Hub was asked to host an oral evidence session in connection with its inquiry which focussed on the next phase of the National Quantum Technologies Programme, and what was needed to support the UK’s quantum industry going forward.
In conjunction with the event at Kelvinhall, QuantIC also exhibited a number of demonstrators such as Wee-g, Indipix and the Multiplexed Single Photon timing Fluorescence system in advance of the session to the committee and also to the public, who had the opportunity to attend. Attending committee members, Rt Hon Norman Lamb MP, Bill Grant MP, Stephen Metcalfe MP and Carol Monaghan MP were “immensively impressed” with what they saw and our “inspiring” researchers.
QuantIC director, Professor Steve Beaumont said, “There is a rich network of collaborative relationships between academia and industry in developing quantum technologies in Scotland and I think the message came across loud and clear to the committee that there are still further opportunities to explore.”

The precision of measuring nanoscopic structures could be substantially improved, thanks to researchers at QuantIC and the University of Warwick. Using pairs of photons, fundamental components of energy that make up light, the researchers have devised a way to measure the thickness of objects that are less than a 100,000th of the width of a human hair. The new technique involves firing two near identical photons onto a component known as a beamsplitter, and monitoring their subsequent behaviour – with some 30,000 photons detected per second, and 500bn in use throughout a full experiment.
Because of the tendency of identical photons to ‘buddy up’ and continue travelling on together — the result of a delicate quantum interference effect – the researchers’ newly developed setup offers the same precision and stability as existing one-photon techniques that, due to the equipment required, are more costly. Offering a range of potential uses, including research to better understand cell membranes and DNA, as well as quality control for nanoscopic 2D materials of a single atom’s thickness, such as graphene, the new research is also a marked improvement on current two-photon techniques with up to 100x better resolution.
To measure the thickness of a transparent object (any object through which a photon is able to pass), each of a pair of identical photons are fired along separate paths:
• Photon A then continues into a beamsplitter, whilst Photon B is slowed down by a transparent object before entering the same beamsplitter.
• The likelihood that the photons exit the beamsplitter together is then recorded allowing researchers to measure the thickness of the transparent object Photon B passed through.
As the thickness of the sample is increased, the photons are more likely to exit the beamsplitter separately.
Dr George Knee of the University of Warwick’s Department of Physics, who developed the theory behind the new method, said,”What’s really exciting about these results is that we can now investigate objects down at the nanoscale with an optical sensor operating on a fundamentally different physical effect.Until now, so-called two-photon interference has not been able to achieve such great resolution, meaning that we are stuck with some of the downsides of the established methods based on single-photon interference – which requires more expensive technology than our new two-photon technique.”
QuantIC co-investigator and lead researcher on the project at the University of Glasgow, Professor Daniele Faccio, whose two photon sensing technology was used to generate the data said, “The results of our collaboration with the University of Warwick offer a range of potential uses in areas such the life sciences, optics and nanofabrication. We are excited to be advancing quantum imaging and helping to maintain the UK’s position in the development of new quantum technologies.”
The research paper, Attosecond-Resolution Hong-Ou-Mandel Interferometry, is published by Science Advances and can be accessed here.
QuantIC’s Professors Robert Henderson and Daniele Faccio were involved in organising the 1st International SPAD Sensor Workshop (ISSW) with Ecole Polytechnique Federal De Lausanne which took place 26-28 February 2018 in Les Diablerets, Switzerland. The workshop which focussed on the study, modelling, design, fabrication and characterisation of SPAD sensors, welcomed more than a hundred participants including many industrial attendees.
Professor Robert Henderson, who is guest editor of an MDPI special issue on the workshop said: “There’s been a growing interest in the field driven by Lidar but there was no forum specifically for SPADs, covering devices, technology and associated applications so the ISSW was organised to bridge the gap to further SPAD development between academia and industry.”
The workshop had a good turnout from industry and companies that presented included ArgoAI, SensL, TowerJazz, and Fastree3D. ST Microelectronics and Austria Microsystems also made product announcements on their multi-zone time of flight sensors. Universities that presented at the workshop included EPFL, Politecnico di Milano, Cornell, Stanford and UCLA. Professors Henderson and Faccio also presented their QuantIC research on SPADs for FLIM and Imaging at the speed of light respectively.
Feedback on the 1st ISSW has been wholly positive and there are plans to organise the next workshop, which will take place biennially, in Scotland. Watch this space.
Former QuantIC researcher from the University of Bristol, Xiao Ai, has started up Quantum Light Metrology (QLM), which has developed a drone mounted, quantum sensing solution capable of remotely detecting and quantifying minute methane leaks. This work was supported by QuantIC, an Impact award and the Quantum Technology Centre (QTEC) at the University of Bristol. The start-up has received funding from Innovate UK and has partnered with ID Quantique and Sky Futures on this venture.
Xiao Ai, founder and Chief Technology Officer at QLM said, “After 4 years of post-doc research developing Laser Radar Lidar for atmospheric sensing of Carbon Dioxide, I realized, that to reduce carbon emission, we first needed to understand the sources and locations of anthropogenic emissions. QLM’s laser radar is capable of remotely detecting and quantifying the lowest leak rate required by the Oil and Gas industry, out to a 150-metre operational distance. This brings a 10-fold sensitivity improvement over our closest competitor, which enables a significant performance improvement in scanning and imaging capabilities.”
QuantIC’s Professor John Rarity co-developed QLM’s technology and is also involved as Chief Scientific Officer. He said, “QuantIC’s input was invaluable as it enabled the continuous funding of this work to develop the first demonstrator buffering that critical gap between academic research and commercial realisation”.
In purely economic terms, methane leaks from well-heads and pipelines cost the Oil and Gas industry between $6bn and $30bn a year. In the US, methane leaks from the natural gas and petroleum industry are now the number one source of methane emissions, surpassing livestock digestion and landfill. Although it is found in much lower concentrations than carbon dioxide, methane is around 25 times more potent, meaning that it still accounts for 28 percent of the amount of warming caused by carbon dioxide.
QLM’s technology is lightweight, low-powered and capable of delivering an unprecedented 30 miles per hour surveying speed when mounted on a drone. This has potential, especially in the Oil and Gas industry for a better understanding of emissions that could result in cost effective mitigating strategies and improved health and safety measures for the sector.
QuantIC wishes QLM all the best!
