Is Quantum Europe an official EU website?
No. It is a prototype platform, independent of the Quantum Flagship website qt.eu. It uses official open data and always links to the original source. About this portal says who runs it.
Where does the project data come from?
EU-funded projects of Horizon 2020 and Horizon Europe come from CORDIS, the European Commission's research information service. Projects of national research funders come from their open data or from the OpenAIRE Graph, and EU cohesion policy projects from Kohesio. The headline figures on the home page count the EU-funded projects only. See Data sources and methods.
Why does a project I know not appear?
The portal shows a project only when its source data names a quantum technology, and only from the sources it reads: CORDIS for EU funding and the national funders listed on the data sources page. Some national funders publish no open data yet. If a project is missing, suggest it.
What does EU contribution mean?
The maximum EU grant agreed for a project. It is not the amount paid out and may differ from the total project cost.
How often is the data updated?
CORDIS publishes new data monthly; the platform refreshes its snapshot when the data changes. Each section shows the retrieval date.
What does suggested, pending review mean?
A tag, such as a technology pillar, proposed by a published keyword rule or, where a page says so, by an AI model. It is not confirmed until an editor approves it.
Does the platform store personal data?
Imported records are about organisations and projects: the portal does not keep the names or contact details of people from its sources. Accounts, the suggestion and feedback forms, the personal briefing and alerts do keep some personal data, described in the privacy notice.
Can I reuse the data?
The portal's own texts and compilations are available under CC BY 4.0. Data from other sources keeps its source's licence, shown with each record: CORDIS data, for example, is available under the European Commission reuse notice. Please cite the source and retrieval date.
Where should I start if I am new to quantum technology?
Open Learn and follow the beginner path. It starts with What are quantum technologies? and Quantum physics basics, then covers each technology and how research reaches the market and is funded. No maths is needed.
What is a qubit?
A qubit is the quantum version of a bit. An ordinary bit is always 0 or 1. A qubit, which can be an atom, an ion, a photon or a small superconducting circuit, can be in a combination of 0 and 1 until it is measured; the measurement then gives a plain 0 or 1. Quantum computers combine many qubits and use interference to make useful results more likely. See Bits and qubits.
Will quantum computers break today's encryption?
A large quantum computer with full error correction could break the public-key methods in wide use today, such as RSA and elliptic-curve cryptography. No such computer exists yet. Symmetric encryption such as AES is much less affected. Because encrypted data can be recorded now and decrypted later, organisations are already moving to post-quantum cryptography: new classical algorithms designed to resist quantum attacks. The US National Institute of Standards and Technology (NIST) published the first standards in 2024, and EU Member States have agreed a coordinated roadmap for the transition. See Post-quantum cryptography.
When will useful quantum computers exist?
Nobody knows for certain. Today's machines are noisy and have limited numbers of qubits, so they are mainly used for research and testing. Large, error-corrected machines need many more and better qubits, and experts disagree on how long that will take. Some early uses, for example simulating molecules and materials, may arrive before general-purpose machines. Treat any precise date with caution.
What is EuroQCI?
The European Quantum Communication Infrastructure is an EU initiative, in which all Member States take part, to build secure communication networks that use quantum technology. It combines fibre links on the ground with satellites and is meant to protect government and critical infrastructure communications. See Quantum communication.
How does Europe fund quantum technologies?
Through several channels: the Quantum Flagship, launched in 2018 under Horizon 2020 and continued under Horizon Europe; the Digital Europe Programme, which funds infrastructure such as EuroQCI; the EuroHPC Joint Undertaking, which procures quantum computers for European supercomputing centres; the Chips Joint Undertaking, which supports pilot lines for quantum chips; QuantERA, a network of national funders that runs joint calls; and national programmes. See Funding instruments and EU funding in Learn.
How can I find partners and opportunities on this site?
Find partners explains the public consortium builder, based on participation in EU-funded projects, and the opt-in matchmaking for signed-in members. Upcoming deadlines lists open calls, tenders and jobs, and Quantum jobs lists positions. Always confirm the details with the original publisher before applying.
How is the information on this site sourced and checked?
Every record comes from a named public source, such as CORDIS, OpenAIRE or official EU documents, and links back to it with the date it was retrieved. Automated steps only suggest tags and links; these are marked as pending until an editor reviews them. Curated lists record when they were last checked. See Data sources and methods.
What are the four technology pillars?
Quantum computing and simulation, quantum communication, quantum sensing and metrology, and enabling technologies and supply chain, as in the draft SRIA 2026 of the Quantum Flagship. Simulation used to be a pillar of its own and is now part of computing. See The four quantum technology pillars.
Who runs the portal and how do I contact it?
The Quantum Europe platform team. About this portal explains its status and how to reach the team.
How do I report an error or a missing record?
Use the suggestion form; no account is needed. Editors check every suggestion against an official source.
How do I cite the portal?
Name the page, its address and the date you read it, and the original source the record shows. The press kit gives a citation text.
