About this position

TU Delft is advertising a PhD position in quantum physics focused on rare-earth ion single-photon emitters for quantum networks. The project explores highly coherent emitters based on erbium ions operating in the telecom C-band and embedded in solid-state crystals such as silicon, with enhancement via photonic crystal cavities.

The work sits in the Groeblacher Lab within the Department of Quantum Nanoscience at Delft University of Technology (TU Delft). The department emphasizes quantum theory, quantum information science, and quantum devices & materials, supported by advanced cleanroom facilities. The role offers training in microfabrication, quantum optics, cryogenics, finite-element simulation, and computer-based experimentation.

Ideal candidates have a Master’s or equivalent in applied physics or engineering, a strong understanding of quantum physics, and are curious and self-motivated. Helpful experience includes quantum optics experiments, nanofabrication, cryogenics, and simulation work. English proficiency is required for PhD study at TU Delft.

The position is a 4-year doctoral employment with an initial 1.5-year contract followed by a 2.5-year extension if progress is satisfactory. Salary ranges from €3204 to €4051 gross per month, plus holiday allowance and an end-of-year bonus. TU Delft also mentions health insurance discounts and a monthly work costs contribution.

Application deadline: 8 November 2026. Apply online through the TU Delft application button, upload a cover letter and CV, and address the application to Simon Groeblacher. Email applications are not processed.
