Clock synchronization with single photons

This thesis addresses the critical issue of clock synchronization in quantum communication systems. While quantum communication offers unmatched security, it demands precise timing, often achieved through resource-intensive methods. This study introduces a postprocessing protocol that eliminates the…

Towards metropolitan free-space quantum networks

Quantum communication has seen rapid progress towards practical large-scale networks, with quantum key distribution (QKD) spearheading this development. While fibre-based systems have been shown to be well suited for metropolitan scales, suitable fibre infrastructure may not always be in place. Here,…

GHz-pulsed source of entangled photons for reconfigurable quantum networks

Entanglement is a universal resource in quantum networks, yet entangled photon sources are typically custom-made for a specific use case. Versatility, both in terms of state modulation and tunability of the temporal properties of the photons, is the key to flexible network architectures and cryptographic…
