The PDRA will investigate aspects of underwater single-photon imaging, and how to integrate quantum detection technologies in underwater vehicles along with other systems for sensor fusion.

The contract is for an initial 24 month period, with a good chance of follow-up funding.

Key Duties and Responsibilities

The post holder is required to;

• Work with colleagues and line manager to devise and perform experiments, modelling and analysis consistent with the goals of the project.

• Write research reports and publications. Analyse and interpret the results of own research and generate original ideas based on outcomes. Prepare proposals and applications to external bodies, e.g. for funding purposes. Use initiative and creativity to identify areas for research, develop new research methods and extend the research portfolio.

• Assist the development of student research skills, and be expected to contribute to the assessment of student knowledge (particularly PhD students) in the context of teaching and supervision duties. Could be expected to contribute to specialist courses such as research methods and equipment.

• Develop research objectives and proposals for own or joint research with the assistance of a mentor, if required. Conduct individual and collaborative research projects, making use of relevant research techniques and methods. Disseminate results of research in peer reviewed journals and conferences, and/or other appropriate media. Continue to update personal knowledge and to develop skills within own specialist research area. Maintain written records of research results and progress generated intellectual property and data analysis. Contribute to the production of research reports and publications.

• Build internal contacts and participate in internal networks for the exchange of information and to form relationships for future collaboration. Work with academic colleagues on areas of shared research interest and contribute to collaborative decision making. Join external networks to share information and identify potential sources of funds.

• Provide guidance as required to support staff, research students and any other students who may be assisting with the research.

• Contribute, under supervision, to the planning of research projects, including the development of new grant/contract proposals. Make internal and external contacts to develop knowledge and understanding and form relationships for future collaboration.

• We are looking for a creative and highly motivated researcher willing to work as part of a team.

• The ideal candidate will have a strong theoretical understanding and an experimental background in semiconductor optoelectronics or closely related field.

• Good communication skills and an appropriate publication record are essential.

• General tasks will involve scientific research; analysis and interpretation of data; daily oversight of the activities of postgraduate and undergraduate project students in the laboratory; communication with other investigators involved in this collaborative project; preparation of scientific papers; presentation of research at conferences.

• The successful candidate will be expected to conduct and lead their own experiments whilst also supervising the activities of junior group members and PhD students.

• Responsibilities will also include assistance in the day-to-day maintenance of the experimental facilities, liaising with companies and external collaborators.

• The successful candidate is also expected to be involved in our outreach activities, with roles that can be tuned to the specific preferences of the candidate but will involve for example interviews, talks for the general public and preparation of experimental demonstrators.

About our Team

The Single-Photon Group at Heriot-Watt have a long:standing track record in researching ground-breaking singlephoton detection, applications in quantum communications and single-photon imaging. With single-photon avalanche diode (SPAD) detectors, we initiated and led collaborations to produce the first custom-designed InGaAs/InP single-photon avalanche diode detector (2006), first strained SiGe SPAD (2002), and custom-designed Ge-on-Si SPAD (2013), and first planar Ge-on-Si SPAD (2018). In quantum communications systems: the first demonstration of a quantum key distribution system operating at GHz clock:rate over an optical fibre link (2004); the first experimental demonstrations of quantum digital signatures (including the first experimental demonstration of quantum digital signatures over installed optical fibre in the Tokyo network) (2015 and 2017). We have pioneered single-photon three-dimensional imaging since the 1990's and continue to innovate, for example being the first to make underwater single-photon imaging demonstrations (2015), first measurements through camouflage (2017), first measurements through fog (2018), first single-photon full colour image reconstruction (2018), and first fully submerged transceiver system for real-time 3D imaging in scattering environments (2023).

Our group has seven laboratories with a total floor area of more than 150 m 2 , including space within a collaborative facility leveraging the skills and technologies of local EPSRC Quantum Enhance Position Navigation and Timing (QEPNT) Hub, EPSRC Quantum Sensing, Imaging, and Timing (QuSIT) Hub, and EPSRC Integrated Quantum Network (IQN) Hub colleagues. The research group has direct ownership of world:leading state:of:the:art equipment with a total value in excess of £3.5 million and shared access to the national network of resources from the Quantum Technology Hub Network. Furthermore, we have a global network of fellow world-leading researchers - offering the possibility of exchanges and collaborations. Access to these resources will allow a motivated candidate to drive the research on underwater singlephoton imaging and sensor fusion within the EPSRC QEPNT Hub, playing a pivotal role in the UK's future threedimensional imaging research using quantum technologies.
