Job description

Are you fascinated by the idea of a next-generation, secure, high-speed space Internet which will enable high-bandwidth and secure communications to every corner of the Earth? Join us on this exciting EU research project with prestigious institutes, observatories and companies throughout Europe. And a warm word of welcome to the information and communication theory lab at the TU/e!

Job Description

Quantum key generation over the satellite is envisioned as part of the core infrastructure for future long-distance, resilient, secure communications. Though the optical losses in the free space optical channel are considerably less than in the fiber channel, for large distances the secure key rates are still very limited. This means in practice that the number of keys, the length of the keys and the rate with which they can be refreshed is limited. To overcome this and enhance the security, in addition to quantum key generation, classical key generation can take place. The classical key generation can be added - on top of the quantum key generation - and inherits its security thanks to the low-divergence of laser beams and by exploiting physical optical channel properties.

As a post-doc you are asked to lead research in this area, give guidance to students and come up with innovative concepts. The research includes defining (realistic) eavesdropper scenarios, perform secrecy analysis and come up with physical layer security schemes (e.g., one-way and two-way) to complement QKD. All with the aim to enhance the security, enable higher secure key rates and longer-distance secure communications.

This position is part of the collaborative EU research project LaiQa which develops key technologies for a global quantum Internet enabled from space. The consortium consists of the Institute of Communication and Computer Systems (ICCS, Greece), the applied research organization TNO (Netherlands), Quantum Technology Laboratories GmbH QTLABS (Austria), Quantum Space Systems GmbH QSSYS (Germany), the National Observatory of Athens (Greece), the National and Kapodistrian University of Athens (Greece), and Thales Alenia Space (Italia).
