Report

JRC technical report (EUR 31594 EN, Cerutti, Lewis and Bonavitacola) on tests of a commercial ID Quantique Cerberis3 fibre QKD system installed at the JRC, run to build experience for supporting EuroQCI. It contrasts classical cryptography with QKD, describes the coherent-one-way protocol and system configuration, and reports secret key rate, quantum bit error rate and interferometer visibility for different fibre lengths and losses.

JRC technical report (EUR 31133 EN, Lewis and Travagnin) describing a pan-European fibre and satellite quantum communications infrastructure. Its first service would be quantum-secured key distribution, later extended to signatures, authentication and secure time distribution, and possibly a network linking quantum computers and sensors. It reviews European and worldwide initiatives, the case for EU-level action, use cases from telecoms to defence and government, and a deployment roadmap with policy challenges.

JRC technology assessment (EUR 30492 EN, M. Travagnin) comparing gyroscopes and accelerometers based on cold atom interferometry with devices using other principles, for space and defence uses. It stresses that absolute measurement and long-term stability could reduce recalibration needs in inertial navigation, including where satellite navigation is unavailable, and situates the assessment within EU activity in Copernicus, Galileo and the emerging defence industrial policy.

JRC technical report (EUR 30289 EN, M. Travagnin) explaining the physics of cold atom interferometry and how it enables high-performance accelerometers, gyroscopes, gravimeters and gravity gradiometers. It assesses the maturity of these sensors, notes uses in autonomous navigation and possible satellite monitoring of Earth's gravity field, and is written for non-specialist EU policymakers dealing with space, defence and Earth observation programmes.

JRC report (EUR 30196 EN) on the Putting Science into Standards workshop on quantum technologies held in Brussels in March 2019, co-organised with CEN, CENELEC, DG CNECT and DIN. It brings together researchers, industry and standardisers to identify which quantum technology areas are ready for early standardisation, notes the many existing standardisation initiatives, for example in the QKD area, and is part of the Flagship-era effort to get the quantum sector ready for industry.

JRC technical report (EUR 29865 EN, Travagnin and Lewis) surveying quantum key distribution deployed outside the laboratory, covering terrestrial and satellite networks funded publicly or privately. It updates the earlier JRC quantum communications report, discusses limits on distance, key rate and fibre compatibility, and was prepared as part of the study defining a vision for a European quantum communication infrastructure. Lab-scale research and one-off small pilots are excluded.

Short JRC technical report (EUR 27039 EN) by Lewis, Ferigato and Breitenbach. Produced under a 2014 JRC quantum cryptography project, it sets out the characteristics that a QKD reference platform, meaning a laboratory or network of laboratories evaluating QKD systems and reporting results publicly or privately, would need in order to be useful to customers, manufacturers and policy-makers. A separate feasibility study was planned as a companion deliverable.

Third part of the JRC series (EUR 29402 EN, Lewis, Ferigato, Travagnin and Florescu). It reports a real-time Delphi survey of experts on research and development options for quantum computing, its expected impact on various sectors, timescales, public and external funding, software and hardware platforms. The survey fed preparations for the Quantum Technologies FET Flagship; participants were broadly positive about the technology's prospects.

Second part of the JRC series (EUR 29017 EN, Lewis and Travagnin) examining quantum communications, with emphasis on quantum key distribution as the most mature application. It explains how QKD reveals eavesdropping during key exchange, notes that commercial systems already exist, discusses the threat that a general-purpose quantum computer poses to current public-key cryptography, and analyses the resulting policy implications for privacy, security and European industry.

First part of a JRC study series (EUR 28555 EN, author A. M. Lewis) on the policy impact of quantum technologies, focused on atomic clocks and precise time. It explains how ultraprecise timing underpins networked infrastructure, timestamping of financial transactions and geo-referenced data, describes the role of national metrology institutes, BIPM and EURAMET, and argues that EU and national law should fully embed the BIPM definition of time.
