Quantum Key Distribution with Entanglement. An interview with Kevin Fuechsel.

Join us for a riveting discussion with Kevin Fuechsel, CEO of Quantum Optics Jena, as we journey through his unconventional path in the world of quantum communications. Starting from his background in semiconductor and photonics to his current ventures in quantum communication, Kevin provides an insightful narrative. His story of founding his company, securing investors, and overcoming the challenges of the quantum field, provides a unique perspective into the journey of a CEO in the quantum industry.

The discussion extends to exploring quantum communication and entanglement-based QKD, as well as the complex process of creating a 24/7 quantum entanglement system. We also examine the story of Carl Zeiss and the development of his company's optical instruments, which eventually led to the establishment of a thriving optics and photonics community in Jena, Germany. Listen in as we break down the importance of quantum memories for effective photon storage in quantum communication, and the future of quantum repeater technology in overcoming distance limitations.

In the final chapters, we shift our focus to the future of quantum communication and quantum key distribution (QKD) with insights from Kevin. Our exploration of quantum networking and market perspectives presents an overview of the current state and future possibilities of QKD technology. From the potential of QKD in longer distance communication to the limitations faced by QKD startups in the US, we unpack the complexities of QKD and the strides being made in the field.
