PhD Student - Quantum Nanophotonics for Next-Generation Quantum Technologies (Open)

The PhD will focus on the theoretical study of nanoscale photon–matter interactions, especially the coupling between quantum emitters (such as organic molecules or quantum dots) and their interaction with optical nanoresonators in advanced quantum nanophotonic architectures.

These hybrid systems are crucial for generating and manipulating non-classical light, entangled states, and other resources for quantum technologies and molecular spectroscopy. The candidate will employ and develop cavity quantum electrodynamics (c-QED) models, enriched when needed by:

• First-principles calculations of excitonic and vibrational responses to feed c-QED Hamiltonians.
• Classical simulations of nano-optical structures to obtain the nanoresonator properties.

The generated states will be characterized through analysis of properties such as quantum correlations (color-blind and frequency-resolved), entanglement, and purity. The ultimate goal is to build increasingly realistic and predictive theoretical models of light-matter interactions at the nanoscale to support and guide experimental research in rapidly evolving fields such as molecular quantum optomechanics or nanophotonic-enhanced entangled photon generation.

We’re seeking a motivated and curious candidate with:

• A Master’s degree (or equivalent) in Physics, Materials Science, Electrical Engineering, or a related field
• Background in quantum optics, cavity QED, or quantum optomechanics (highly valued)
• Interest or experience in nanophotonics, molecular spectroscopy or computational modeling (appreciated)
• Initiative to participate actively in ongoing collaborations with leading international theoretical and experimental groups

• Estimated annual gross salary: Salary is commensurate with qualifications and consistent with our pay scales
• Target start date: 2026/04/15

We provide a highly stimulating research environment, and unique professional career development opportunities.

We offer and promote a diverse and inclusive environment and welcomes applicants regardless of age, disability, gender, nationality, ethnicity, religion, sexual orientation or gender identity.

The thesis will be supervised by Javier Aizpurua and Ruben Esteban in the Theory of Nanophotonics Group, which is based at DIPC and the Centro de Física de Materiales (CFM) in San Sebastián. The group has pioneered studies of quantum effects in nanoscale optical systems, with current interest in the use of nanophotonics for quantum technologies, field-enhanced spectroscopy, and microscopy

Interested candidates should submit an updated CV and a brief statement of interest to the following application email below. 

Reference letters are welcome but not indispensable.

The reference of the specific opening to which the candidate is applying should be stated in the subject line, and the application must be received before the application deadline.

Although candidates are welcome to contact the project supervisors to know further details about the proposed research activity, please be aware that the application will be evaluated only if it is submitted directly to the email address listed below as application email.

• Reference: 2026/04
• Application deadline: 2026/02/09
• Application email: jobs.research@dipc.org

Applications received by the deadline will be evaluated by a Committee designed by the DIPC board on the basis of the following criteria:

• CV of the candidate (60%)
• Adequacy of the candidate’s scientific background to the project (20%)
• Reference letters (10%)
• Other: Diversity in gender, race, nationality, etc. (10%)

Evaluation results will be communicated to the candidates soon after. Positions will only be filled if qualified candidates are found.

The DIPC may revoke its decision if the candidate fails to join by the appointed time, in which case the position will be awarded to the candidate with the next highest score, provided it is above 50 (out of 100).

However, the selected candidate may keep the position if, in the opinion of the Selection Committee, the candidate duly justifies the reasons why he or she cannot join before the specified deadline, and as long as the project allows it.

The contract is part of the CEX2024-001491-S grant, funded by MICIU/AEI/10.13039/501100011033
