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.

JOB DESCRIPTION

Most applications of quantum networks (networks of quantum devices) require entanglement between nodes in the network. Such long-distance entanglement is typically constructed by a quantum repeater chain: first generating multiple entangled pairs of qubits at short distances, followed by using quantum teleportation to connect the short-distance pairs to long-distance entanglement.
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.
At QuTech, we value a diverse and inclusive research environment, and we strongly encourage applications from women and other underrepresented groups in science and technology.

REQUIREMENTS

We are looking for a motivated candidate with a Master’s degree in Computer Science, Physics, or a closely related field and with demonstrable experience or solid foundation in quantum computing or quantum information (for example through coursework).
Previous experience with quantum networks or related fields, for example as part of a master thesis or internship, is preferred, but not strictly necessary.
