Large-scale quantum networks with thousands of nodes require scalable network protocols
and physical hardware to realize. In this paper, we introduce packet switching as a paradigm …

In this article a fibre free-space fibre link that allows a quantum key distribution (QKD) signal
and high-speed data to be transmitted in a single optical beam is presented. This setup has …

The commercial success and wide deployment of quantum key distribution (QKD)
technology depend on the integration of QKD links into existing fiber networks and sharing …

A successful commercial deployment of quantum key distribution (QKD) technologies
requires integrating QKD links into existing fibers and sharing the same fiber networks with …

Long block length rate-compatible low-density parity-compatible (LDPC) codes are
designed to solve the problems of great variation of quantum channel noise and extremely …

This contribution focuses on experimental verification of the QKD system deployment in a
multi-domain network environment managed by Czech and Polish National Research and …

In this paper, we investigate the impact of classical optical communications in quantum key
distribution (QKD) over hollow-core fiber (HCF), multi-core fiber (MCF) and single-core fiber …

To face the quantum era and the prospect or threat of quantum computing, especially in a
disaggregated network environment, the design and implementation of efficient quantum …

Raman scattering is the inelastic process where photons bounce off molecules, losing
energy and becoming red-shifted. This weak effect is unique to each molecular species …

Recent progress in the development and applications of microstructured optical fibres for
quantum technologies is summarised. The optical nonlinearity of solid-core and gas-filled …
