Fixed-term: The funds for this post are available for 34 months in the first instance.
Applications are invited for a Post-Doctoral Research Associate to join the group of Dr Raj Pandya in the Department of Chemistry at the University of Cambridge. The position is funded for 34 months through the UK-US project REACT-Q (entanglement tRansfEr And Correlations in polaritonic chemisTry with Quantum light), undertaken in close collaboration with Professor Milan Delor's group at Columbia University. The project asks whether non-classical properties of light, including photon correlations, squeezing and entanglement, can be transferred to and preserved within molecular exciton-polaritons in on-chip waveguides, and how those correlations evolve during chemically relevant processes such as singlet fission.
The successful applicant will lead the Cambridge experimental quantum-optics programme. They will:
- Develop and characterise entangled-photon-pair and bright squeezed vacuum sources
- Perform photon-correlation measurements including g(2) and Hanbury Brown-Twiss measurements
- Undertake Hong-Ou-Mandel interference and joint spectral correlation/entanglement measurements
- Couple non-classical light into molecularly clad photonic waveguides
They will quantify the effects of matter fraction, propagation length, loss, disorder and molecular cladding on photon statistics, spectral correlations and two-photon indistinguishability, and contribute to quantum pump-probe measurements of singlet fission. The role will involve close collaboration with Columbia University, including exchange of samples and data and research visits to Columbia, as well as preparation of publications, presentation of results, and support for the wider activities of the collaboration.

Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Applicants must have, or be close to obtaining, a PhD in experimental quantum optics, quantum photonics, photonics, physics, physical chemistry, electrical engineering, or a closely related field. Hands-on experience in quantum optics, photonics, or a related area of optical experimentation is essential. Experience in one or more of the following would be highly desirable:
- Hong-Ou-Mandel interference
- Second-order photon-correlation [g(2)] or coincidence measurements
- SPDC or other non-classical light sources
- Spectral-correlation or entanglement measurements
- Bright squeezed vacuum or other squeezed/multimode sources
- Single-photon detectors and timing electronics
- Coupling or characterising light in integrated photonic waveguides
Candidates are not expected to have prior experience in all of these areas, and training will be provided in techniques that are new to them. Good optical alignment, data-analysis and scientific-programming skills are essential. Experience of molecular exciton-polaritons, silicon photonics, quantum-state reconstruction, or international collaborative research would be a bonus but are not required.
The applicant will be expected to work independently while contributing actively to a highly interdisciplinary UK-US team spanning quantum optics, ultrafast spectroscopy, nanophotonics and chemical physics. Excellent communication, organisational and collaborative skills are required.
