PhD positions & Postdoc position in Quantum Networks

The aim of the BMFTR research project “Q-Cyber” is to explore new approaches to networked multi-party quantum communication applications and to evaluate their practical feasibility and security. We will implement and investigate a range of advanced multipartite quantum communication protocols. We will develop suitable hardware solutions for the use of multipartite entangled quantum states as a fundamental resource in future quantum networks.

We will test quantum-networked communication under application-oriented conditions in a real fibre-optic network within an academically and industrially oriented ecosystem.

Join our cutting-edge research team realise quantum networks and to bring multipartite quantum communication protocols to real life:

• Work on the technical realisation of real-life multipartite quantum networks with multiple node and photonic quantum hardware

You have:

• Interest in collaborative and interdisciplinary research
• MSc in Physics, or related
• Experience in experimental quantum optics and (photonic) quantum technologies

The positions are fixed term and available until filled . The positions are funded via the Federal Ministry for Research, Technology and Space, Project Q-Cyber(75% TVL E13).
