The development of secure quantum networks, based on highly reliable communication protocols, is entering a decisive phase. One of the main research challenges remains the problem of signal loss and imperfections during long-distance transmission.

During the upcoming seminar, organized by the Center for Hybrid Quantum-Classical Information Technologies (QLAB), Dr. Jean-Luc Dubois from Sorbonne University will present an innovative approach to designing hybrid telecommunications interfaces. He will demonstrate how photonic hardware, based on advanced light manipulation, can operate alongside classical systems without the full error correction characteristic of the NISQ era.

Seminar Agenda:

  • Overview of modern photonic platforms and their scalability.
  • Discussion of hybrid solutions for secure quantum communication.
  • Presentation of early technology demonstrator models.
  • Discussion on the commercial potential of such solutions in the cybersecurity sector.

This event is aimed at researchers and students working in deep tech, as well as business representatives interested in early technology transfer. Following the presentation, we have scheduled an open Q&A session where you can ask the expert questions directly.
