Phd Position in Quantum Networks: Entanglement Distribution with Classical Communication Delays

**PhD Position in Quantum Networks: Entanglement Distribution with Classical Communication Delays**:
**_Join QuTech, the quantum technology institute at TU Delft We are looking for a master student who would like to pursue a PhD in developing and analysing protocols for remote-entanglement distribution in quantum networks._**_
- **

Although a variety of policies for quantum repeaters exist, these typically assume all nodes have global knowledge that at any point in time. That is, they know which pairs of nodes share entanglement. In practice, however, classical communication delays are significant, and the incurred waiting time for classical messages to arrive makes existing entanglement decay.

In this project, the goal is to investigate how nodes best take actions based on partial information of the network. We will study how well such partial-knowledge policies perform compared to the global-knowledge case, and what the implications are for quantum network design.

For this position, the **main supervisor** will be Dr Tim Coopmans and the **promotor** will be Prof Stephanie Wehner.

**Requirements**:
Previous experience with quantum networks or related fields, for example as part of a master thesis or internship, is preferred, but not strictly necessary.

**TU Delft**

Delft University of Technology is built on strong foundations. As creators of the world-famous Dutch waterworks and pioneers in biotech, TU Delft is a top international university combining science, engineering and design. It delivers world class results in education, research and innovation to address challenges in the areas of energy, climate, mobility, health and digital society. For generations, our engineers have proven to be entrepreneurial problem-solvers, both in business and in a social context.

Challenge. Change. Impact

**QuTech**

QuTech is a mission-driven research institute run jointly by Delft University of Technology (TU Delft) and the Netherlands Organisation for Applied Scientific Research (TNO). Together, we work on a radically new technology with world-changing potential, developing scalable prototypes of a quantum computer and an intrinsically safe quantum internet.

We are creating the quantum future, and we believe that quantum technology will be a game changer in many social and economic sectors - including health, agriculture, climate and safety. To achieve our ambitious goals, we bring together scientists, engineers and industry in an inspiring environment, with plenty of space for ambition, entrepreneurship and innovation. Our research and engineering activities are conducted in three divisions: Quantum Computing, Quantum Internet and Qubit Research. 220 FTE and over 300 curious people work in our divisions and support teams, and we actively welcome new colleagues who share our vision and enthusiasm.
