Quantum key distribution (QKD) provides in principle unconditional security of key sharing
based on the laws of physics only. In the last decade, several experimental and commercial …

Quantum technologies promise major advances in different areas. From computation to
sensing or telecommunications, quantum implementations could bring significant …

The Key Management System (KMS) is an important component in scaling up from link-to-
link key generation to large key distribution networks. In this work we provide an overview of …

Quantum key distribution (QKD) is an effective technique to share unconditional secure keys
among a pair of legal distant users with the existence of eavesdroppers. It depends upon …

We present a practical quantum/classical multiplexing scheme in a mobile x-haul optical
transport segment deployed in a fiber pair. Photon counting measurements are reported …

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 …

Any human-designed system can potentially be exploited in ways that its designers did not
envision, and information systems or networks using quantum components do not escape …

Public key cryptography is nowadays a crucial component of global communications which
are critical to our economy, security and way of life. The quantum computers are expected to …

This paper analyses a classical and a quantum annealing approach to compute the
minimum deployment of Quantum Key Distribution (QKD) hardware in a tier 1 provider …
