A novel approach to quality-of-service provisioning in trusted relay Quantum Key Distribution networks
In recent years, noticeable progress has been made in the development of quantum equipment, reflected through the number of successful demonstrations of Quantum Key Distribution (QKD) technology. Although they showcase the great achievements of QKD, many practical difficulties still need to be resolved. Inspired by the significant similarity between mobile ad-hoc networks and QKD technology, we propose a novel quality of service (QoS) model including new metrics for determining the states of public and quantum channels as well as a comprehensive metric of the QKD link. We also propose a novel routing protocol to achieve high-level scalability and minimize consumption of cryptographic keys. Given the limited mobility of nodes in QKD networks, our routing protocol uses the geographical distance and calculated link states to determine the optimal route. It also benefits from a caching mechanism and detection of returning loops to provide effective forwarding while minimizing key consumption and achieving the desired utilization of network links. Simulation results are presented to demonstrate the validity and accuracy of the proposed solutions.Web of Science28118116
Quantum information processing with space-division multiplexing optical fibres
The optical fibre is an essential tool for our communication infrastructure
since it is the main transmission channel for optical communications. The
latest major advance in optical fibre technology is spatial division
multiplexing (SDM), where new fibre designs and components establish multiple
co-existing data channels based on light propagation over distinct transverse
optical modes. Simultaneously, there have been many recent developments in the
field of quantum information processing (QIP), with novel protocols and devices
in areas such as computing, communication and metrology. Here, we review recent
works implementing QIP protocols with SDM optical fibres, and discuss new
possibilities for manipulating quantum systems based on this technology.Comment: Originally submitted version. Please see published version for

Characterizing and Utilizing the Interplay between Quantum Technologies and Non-Terrestrial Networks
Quantum technologies are increasingly recognized as groundbreaking
advancements set to redefine the landscape of computing, communications, and
sensing by leveraging quantum phenomena, like entanglement and teleportation.
Quantum technologies offer an interesting set of advantages such as
unconditional security, large communications capacity, unparalleled
computational speed, and ultra-precise sensing capabilities. However, their
global deployment faces challenges related to communication ranges and
geographical boundaries. Non-terrestrial networks (NTNs) have emerged as a
potential remedy for these challenges through providing free-space quantum
links to circumvent the exponential losses inherent in fiber optics. This paper
delves into the dynamic interplay between quantum technologies and NTNs to
unveil their synergistic potential. Specifically, we investigate their
integration challenges and the potential solutions to foster a symbiotic
convergence of quantum and NTN functionalities while identifying avenues for
enhanced interoperability. This paper not only offers useful insights into the
mutual advantages but also presents future research directions, aiming to
inspire additional studies and advance this interdisciplinary collaboration
