“…Recent decades have established a solid physical basis for quantum key distribution (QKD) (1–5). Constant technological advancement has seen QKD extend to ever-longer distances (6, 7) and with increased key generation rates (8), linking cities (5, 9) and even continents via satellite links (10–13). Efforts are also well underway to extending QKD from point-to-point links to secure network infrastructures (9, 14–19).…”

“…Constant improvement has seen the experiments distribute cryptographic keys over ever-longer distances [7,8] and increase the speed of key generation [9][10][11]. Intrinsically a point-to-point technology, QKD can however be combined with other ideas to extend quantum security to entire networks [12][13][14][15][16][17][18][19]. Effort is also well underway to expand the reach of QKD systems, aiming at linking cities [5,18]; connecting continents with space-based links [20][21][22][23] has also been demonstrated, thus ushering in the possibility of a quantum-secure world-wide network.…”

Quantum entanglement is one of the most extraordinary effects in quantum physics, with many applications in the emerging field of quantum information science. In particular, it provides the foundation for quantum key distribution (QKD), which promises a conceptual leap in information security. Entanglement-based QKD holds great promise for future applications owing to the possibility of device-independent security and the potential of establishing global-scale quantum repeater networks. While other approaches to QKD have already reached the level of maturity required for operation in absence of typical laboratory infrastructure, comparable field demonstrations of entanglement-based QKD have not been performed so far. Here, we report on the successful distribution of polarization-entangled photon pairs between Malta and Sicily over 96 km of submarine optical telecommunications fiber. We observe around 257 photon pairs per second, with a polarization visibility above 90%. Our results show that QKD based on polarization entanglement is now indeed viable in long-distance fiber links. This field demonstration marks the longest-distance distribution of entanglement in a deployed telecommunications network and demonstrates an international submarine quantum communication channel. This opens up myriad possibilities for future experiments and technological applications using existing infrastructure.

Conceptualising centres of excellence: a scoping review of global evidence

et al. 2022

ObjectiveGlobally, interest in excellence has grown exponentially, with public and private institutions shifting their attention from meeting targets to achieving excellence. Centres of Excellence (CoEs) are standing at the forefront of healthcare, research and innovations responding to the world’s most complex problems. However, their potential is hindered by conceptual ambiguity. We conducted a global synthesis of the evidence to conceptualise CoEs.DesignScoping review, following Arksey and O’Malley’s framework and methodological enhancement by Levac et al and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews.Data sourcesPubMed, Scopus, CINAHL, Google Scholar and the Google engine until 1 January 2021.EligibilityArticles that describe CoE as the main theme.ResultsThe search resulted in 52 161 potential publications, with 78 articles met the eligibility criteria. The 78 articles were from 33 countries, of which 35 were from the USA, 3 each from Nigeria, South Africa, Spain and India, and 2 each from Ethiopia, Canada, Russia, Colombia, Sweden, Greece and Peru. The rest 17 were from various countries. The articles involved six thematic areas—healthcare, education, research, industry, information technology and general concepts on CoE. The analysis documented success stories of using the brand ‘CoE’—an inﬂuential brand to stimulate best practices. We identified 12 essential foundations of CoE—specialised expertise; infrastructure; innovation; high-impact research; quality service; accreditation or standards; leadership; organisational structure; strategy; collaboration and partnership; sustainable funding or financial mechanisms; and entrepreneurship.ConclusionsCoEs have significant scientific, political, economic and social impacts. However, there are inconsistent use and self-designation of the brand without approval by an independent, external process of evaluation and with high ambiguity between ‘CoEs’ and the ordinary ‘institutions’ or ‘centres’. A comprehensive framework is needed to guide and inspire an institution as a CoE and to help government and funding institutions shape and oversee CoEs.

ObjectiveGlobally, interest in excellence has grown exponentially, with public and private institutions shifting their attention from meet targets to achieving excellence. Centers of Excellence (CoEs) are standing at the forefront of healthcare, research, and innovations responding to the world’s most complex problems. However, their potential is hindered by conceptual ambiguity. We conducted a global synthesis of the evidence to conceptualize CoEs.DesignScoping review, following Arksey and O’Malley’s framework and methodological enhancement by Levac et al to analyze the evidence and the PRISMA-ScR to guide the retrieval and inclusion of the evidence.Data sourcesPubMed, Scopus, CINAHL, Google Scholar, and the Google engine from their inception to 01 January 2021.EligibilityPapers that describe CoE as the main theme, which could be defining, theorizing, implementing, or evaluating a CoE.ResultsThe search resulted in 52,161 potential publications, with 78 articles met the eligibility criteria. The 78 articles were from 33 countries, of which 35 were from the United States of America, 3 each from Nigeria, South Africa, Spain, and India, and 2 each from Ethiopia, Canada, Russia, Colombia, Sweden, Greece, and Peru. The rest 17 were from various countries. The articles involved six thematic areas - healthcare, education, research, industry, information technology, and general concepts on CoE. The analysis documented success stories of using the brand “Center of Excellence” - an influential brand to stimulate technical skills, innovation, and technology. We identified 12 essential foundations of CoE - specialized expertise; infrastructure; innovation; high-impact research; quality service; accreditation or standards; leadership; organizational structure; strategy; collaboration and partnership; sustainable funding or financial mechanisms; and entrepreneurship.ConclusionsCoEs have significant scientific, political, economic, and social impacts. A comprehensive framework is needed to guide and inspire an institution as a CoE and to help government and funding institutions shape and oversee CoEs.Strengths and limitations of this study-To the best of our knowledge, this is the first scoping review to conceptualize centers of excellence based on global evidence.-The study followed Arksey and O’Malley’s framework and methodological enhancement by Levac et al to and the PRISMA-ScR methodological frameworks.-Five databases were systematically searched to identify scientific and gray literature-The study was limited by language restrictions.
