Current distance limitations of quantum key distribution (QKD) over fibre optic networks suggest that satellite (free-space optical) QKD will be required to enable global communications. However, the operational availability these systems is limited by background noise and strong attenuation caused turbulence adverse weather conditions. Using decoy-state BB84 protocol, we evaluate secret rate for a range wavelengths, receiver sizes initial beam waists through variety atmospheric We combine...
The Internet of Things (IoT) concept has attracted a lot attention from the research and innovation community for number years already. One key drivers this hype towards IoT is its applicability to plethora different application domains. However, infrastructures enabling experimental assessment solutions are scarce. Being able test assess behavior performance any piece technology (i.e., protocol, algorithm, application, service, etc.) under real-world circumstances utmost importance increase...
The Smart Grid relies in Information and Communication Technologies (ICT) but usually there is still a lack of integration their deployment.They are designed as separated systems managed that way too.In addition, the changes electric network so complex dependable on very rigid hardware architecture.Based work done European project FINESCE, this paper presents "Software Defined Utility "(SDU) concept, which advocates migration utility infrastructure to software instead relying based...
Quantum computing has the power to break current cryptographic systems, disrupting online banking, shopping, data storage and communications. also support stronger more resistant technologies. In this paper, we describe a digital cash scheme created by Dmitry Gavinsky, which utilises capability of quantum computing. We contribute setting out methods for implementing scheme. For both creation verification coins convert algebraic steps into steps. As part this, used information stored on...
We investigate resource allocation for quantum entanglement distribution over an optical network. characterize and model a network architecture that employs single quasi-deterministic time-frequency heralded Einstein-Podolsky-Rosen (EPR) pair source, develop routing scheme distributing entangled photon pairs such focus on max-min fairness in compare the performance of various spectrum schemes by examining median number EPR-pairs assigned them, Jain index associated with this assignment....
Space quantum communications is a potential means for establishing global secure and networking. Despite pioneering demonstrations of satellite key distribution, considerable challenges remain wide deployment such as the local effects atmosphere on transmission single-photon level signals. As part Ireland's efforts to establish links with rest Europe further afield, we present preliminary study feasibility distribution taking into account geographic weather space-Earth channel. Weather data...
We consider quantum networks, where entangled photon pairs are distributed using fibre optic links from a centralized source to entangling nodes. The entanglement is then stored (via an swap) in nodes' memories until used in, e.g., computing, key distribution, sensing, and other applications. Due the loss, some photons lost transmission. Noise transmission link memory also reduces fidelity. Thus, nodes must keep updated records of photon-pair arrivals each destination, their use by This...
Daidalos II [1] works towards its overall mission of providing a beyond 3G Framework that is capable supporting pervasive services built on network and service infrastructures for mobile end users. In order to validate such framework, worked the completion prototype demonstrator was verified specific testbed infrastructure, enabling user validation framework. Having infrastructure up running with components installed, provides valuable opportunity consortium realistically debug evaluate...
We investigate resource allocation for quantum entanglement distribution over an optical network. characterize and model a network architecture that employs single quasideterministic time-frequency heralded EPR-pair source, develop routing scheme distributing entangled photon pairs such focus on fairness in distribution, compare both the performance of various spectrum schemes as well their Jain index.

Quantum computing has the power to break current cryptographic systems, disrupting online banking, shopping, data storage and communications. However, quantum mechanics can also be used make these systems stronger more resilient. In this paper we describe transmissibility of a money scheme, which was proposed by Dmitry Gavinsky implemented authors, discuss some its benefits limitations.
