evidence: The Worldwide LHC Computing Grid (WLCG) – a distributed computing infrastructure arranged in tiers – gives a community of thousands of physicists near real-time access to LHC data. The CERN data centre is at the heart of WLCG, the first point of contact between experimental data from the LHC and the grid. Through CERN openlab, a unique public-private partnership, CERN collaborates with leading ICT companies and other research organisations to accelerate the development of cutting-edge ICT solutions for the research community. CERN has also established a medium- and long-term roadmap and research programme in collaboration with the high energy physics and quantum-technology research communities via the CERN Quantum Technology Initiative (QTI). [...] The large-scale data challenges of HL-LHC are also shared with other science communities. WLCG and CERN have been working with the Square Kilometre Array (SKA) radio astronomy community to explore some of these common challenges. In June 2017, CERN and the SKA Organisation signed a Collaboration Agreement for joint work in computing and data management.
