PhD Opportunities in Quantum Optics in Portugal

This PhD project at Eindhoven University of Technology focuses on entanglement routing in quantum optical fiber networks , combining theory, simulation, and experimentation to build telecom-grade quantum networking technologies. You will develop an entanglement-based routing architecture and protocol and set up an experimental multi-node testbed for routing entangled photons alongside classical telecom traffic. The project investigates how quantum-classical packets can be generated, detected, fr...

[Maintenance stipend at UELA enhanced rate; expected to be £26,022 for 2026/27, about £1,500 above the UKRI London-weighted rate of £24,522.] This PhD studentship at University College London explores the use of terahertz (THz) photons as a new resource for quantum control and topological quantum information. The project sits at the intersection of quantum optics, condensed-matter theory and numerical modelling, with a focus on how THz radiation can manipulate matter at the single- and few-photo...

At DTU Physics, four PhD students will join a broad quantum science effort spanning experimental quantum optics, optomechanics, microscopy and theory/software for photonic quantum computing. The positions are based in the Section for Quantum Physics and Information Technology (QPIT) and bigQ – Center for Macroscopic Quantum States , within an international environment that combines advanced quantum-optical laboratories, quantum information theory and large-scale computational research. The adver...

The Karlsruhe School of Optics & Photonics (KSOP) at the Karlsruhe Institute of Technology offers a structured PhD programme focused on optics and photonics , two technologies at the centre of modern optical communications, sensing, biomedical diagnostics, lighting, and solar energy applications. The school is positioned at the interface of the natural sciences and engineering disciplines and brings together research across several closely linked areas. Doctoral researchers in KSOP can work acro...

The Max Planck School of Photonics offers a structured Master’s to PhD direct-track programme based at Friedrich Schiller University Jena and delivered through a network of teaching universities including Friedrich Schiller University Jena , Friedrich-Alexander University Erlangen-Nuernberg , and Karlsruhe Institute of Technology . The programme is organised in two phases. Applicants with a qualifying Master’s degree can move directly into the three-year research phase and begin their PhD resear...

PhD opportunity in photonic quantum error correction at the Niels Bohr Institute, University of Copenhagen. The project sits within the Novo Nordisk Foundation Quantum Computing Programme (NQCP), an international quantum computing initiative in Copenhagen that works on scalable quantum processor technologies, quantum algorithms and applications, with a long-term goal of fault-tolerant hardware and algorithms for life-science-relevant problems. This PhD focuses on fault-tolerant photonic quantum ...

Technical University of Denmark (DTU) Physics is recruiting four PhD students in the Section for Quantum Physics and Information Technology (QPIT) and bigQ – Center for Macroscopic Quantum States. The positions combine advanced quantum-optical laboratories, quantum information theory and large-scale computational research in an international environment. The projects address frontier problems in quantum physics. In quantum opto-acoustics , the researcher will use cavity-enhanced Brillouin intera...

This four-year PhD project in advanced signalling and detection in quantum communications explores how quantum communication systems can remain effective when quantum states and communication channels are uncertain. The research will design and optimise resilient quantum signalling constellations for conveying classical information. In particular, the project will investigate constellation designs that maximise minimum trace distance and uniform Holevo-x information, addressing the limits impose...

This PhD project will develop high-bandwidth quantum frequency converters for future hybrid quantum networks. The research addresses a central challenge in quantum networking: quantum technologies often operate at incompatible optical wavelengths. Visible single-photon sources, telecom communication channels and atomic quantum memories therefore require interfaces capable of translating photons between wavelength regimes. The project will use four-wave mixing in warm rubidium vapour to develop t...
