About our Team
The Quantum Photonics Laboratory at Heriot-Watt University (HWU) is engaged in research covering solid-state photonics, engineering coherent light-matter interaction using quantum structures and devices, and exploiting such devices for quantum technologies. The group consists of about 25 members, including five academics: Prof Margherita Mazzera, Prof Cristian Bonato, Prof Brian Gerardot, Dr Mauro Brotons i Gisbert, Samer Kurdi and Dr Christian Bekker. The quantum photonic platforms used within the group includes rare-earth doped crystals, defects in wide band-gap materials such as SiC or diamond, two-dimensional materials ‘beyond graphene’, quantum dots in III-V semiconductors.
The group has well-equipped laboratories for quantum optics and high-resolution laser spectroscopy of quantum emitters at room and cryogenic temperatures, radio-frequency control of electronic/nuclear spins as well the facilities for fabrication of novel optoelectronic / quantum photonic devices.
The group is affiliated to the Institute of Photonics and Quantum Science (IPaQS), which is one of the UK's largest photonics-oriented research institutes. IPaQS has a strong culture of collaborative research, which is built on the regular exchange of ideas between our experimental and theory groups. We are a tight-knit community of academics that support each other’s career development.
We have a strong commitment to equity, diversity, and inclusion, and hold regular events that celebrate our diversity and raise awareness about issues affecting the IPaQS community. We boast world-class research facilities, including a 275m2 cleanroom and 2175m2 of high specification optics and laser laboratories, providing the infrastructure needed to conduct internationally leading research in photonics and quantum sciences. The UK Research and Excellence Framework (REF2021) saw Heriot-Watt Physics ranked first in Scotland and 4th in the UK for world-leading research.
IPaQS is part of the School of Engineering and Physical Sciences (EPS) at Heriot-Watt. The University and EPS hold an Institutional and School-level Athena Swan Bronze Award, recognising excellence in championing the advancement of the careers of women in science, technology, engineering and mathematics. We offer a range of family-friendly and inclusive employment policies, flexible working arrangements, staff engagement forums, campus facilities and services to support staff from different backgrounds. Our staff hail from many countries around the world and we pride ourselves as being a welcoming and inclusive place to work.
Detailed Description
The Quantum Photonics Laboratory seeks a talented and motivated scientist to lead a new research direction on integrated photonic platforms for quantum memories based on rare-earth doped crystals. This role will focus on developing advanced quantum devices that combine optical resonators and microwave (MW) circuits for high-performance quantum memory applications.
Key objectives include:
1. manipulation and optimization of electronic and spin coherence through complex optical and MW sequences,
2. implementation of quantum memory protocols in both bulk crystals and waveguide structures,
3. design and integration of MW coils and circuits with photonic components, including optical resonators.
The project aims to deliver high-impact scientific publications and technological advances in integrated quantum photonic devices for quantum communication and computation. The work will be conducted within a recently funded EPSRC project, in collaboration with world-leading partners in waveguide fabrication and microwave engineering. The successful candidate will work under the supervision of Prof Margherita Mazzera, Principal Investigator of the project.

Key Duties and Responsibilities
The post holder is required to:
Undertake the following key tasks of this project:
17. Operate, maintain and modify, when necessary, a quantum memory experimental setup including tuneable lasers, cryocoolers, vacuum systems, arbitrary waveform generators for the manipulation of atomic and spin excitations, and MW sources for the control of spins.
18. Carry out other general tasks involved in scientific research as analysis and interpretation of data, and daily oversight of the activities of postgraduate and undergraduate project students in the laboratory.
Carry out the research project to a high standard by:
19. Meeting planned milestones and deliverables.
20. Reporting progress regularly to supervisors, both verbally and in written reports
21. Keeping clear written records of work done and storing data in accessible formats according to a system agreed with the project supervisor.
Collaborate with partners within the project and others as appropriate:
The post holder will join the Quantum Photonics Laboratory and will be expected to;
22. Work collaboratively and cooperatively in a team environment; this involves shared use of laboratory equipment (therefore effective communication between group members is essential).
