Evaluation results are expected to be communicated in July 2026.
The European Commission intends to cancel this topic. As of today, therefore, the submission platform for this topic is no longer accessible.
The envisioned cancellation follows the adoption of COUNCIL REGULATION (EU) 2026/150 of 16 January 2026 amending Regulation (EU) 2021/1173 on establishing the European High Performance Computing Joint Undertaking, which enlarged the mandate of EuroHPC joint undertaking to encompass, inter alia, quantum technologies. Consequently, EuroHPC JU may include in its own work programme for 2026 similar topics and potentially open them for submission in the second half of this year. Any relevant information will be made available by EuroHPC JU and information on all calls decided under the EuroHPC work programmes is also available eurohpc-ju.europa.eu. Applicants may also refer to the EuroHPC JU website.
The cancellation is subject to the update of the Work Programme, once all necessary procedural steps for its adoption are finalised. It is currently foreseen in fourth quarter of 2026.
The submission session is now available for: HORIZON-CL4-2026-04-DIGITAL-EMERGING-18, HORIZON-CL4-2026-04-DIGITAL-EMERGING-17, HORIZON-CL4-2026-04-HUMAN-02, HORIZON-CL4-2026-04-DIGITAL-EMERGING-01, HORIZON-CL4-2026-04-DATA-03, HORIZON-CL4-2026-04-DIGITAL-EMERGING-08, HORIZON-CL4-2026-04-DATA-06, HORIZON-CL4-2026-04-DATA-02, HORIZON-CL4-2026-04-DIGITAL-EMERGING-12, HORIZON-CL4-2026-04-DIGITAL-EMERGING-09, HORIZON-CL4-2026-04-DIGITAL-EMERGING-11, HORIZON-CL4-2026-04-DIGITAL-EMERGING-19, HORIZON-CL4-2026-04-HUMAN-01, HORIZON-CL4-2026-04-DIGITAL-EMERGING-14, HORIZON-CL4-2026-04-DIGITAL-EMERGING-15
This action will establish a strategic European initiative to develop scalable, modular, and interoperable photonic quantum computing platforms. Proposals for this topic are expected to address and provide credible solutions to at least two major technical roadblocks currently limiting the advancement of photonic quantum computing such as:
Project results are expected to contribute to the following expected outcomes:
Proposals for this topic are expected to be led by a startup with demonstrated expertise in photonic quantum computing. The startup should collaborate with relevant academic, industrial, and RTO partners to ensure both technological depth and market orientation. The consortium should also include at least one major end-user whose operational needs will shape the platform design, and whose infrastructure will host the field demonstration of the project’s results.
Proposals should implement a coordinated, durable R&I programme that integrates hardware, software, system architecture, and application-level use cases. Activities should include:
Proposals are expected to build upon prior Quantum Flagship results and demonstrate capacity to contribute actively to the governance and strategic coordination of the EU quantum computing ecosystem, including synergies with STEP, Chips JU, IPCEI projects and EuroHPC.
This topic is cancelled. The cancellation follows the adoption of Council Regulation (EU) 2026/150 of 16 January 2026 amending Regulation (EU) 2021/1173 on establishing the European High Performance Computing Joint Undertaking (‘EuroHPC JU’), which enlarged the mandate of EuroHPC JU to encompass, inter alia, quantum technologies.

Activities are expected to start at TRL 4 and achieve TRL 7 by the end of the project – see General Annex B.
1. Admissibility Conditions: Proposal page limit and layout
Described in Annex A and Annex E of the Horizon Europe Work Programme General Annexes.
Proposal page limits and layout: described in Part B of the Application Form available in the Submission System.
2. Eligible Countries
Described in Annex B of the Work Programme General Annexes.
A number of non-EU/non-Associated Countries that are not automatically eligible for funding have made specific provisions for making funding available for their participants in Horizon Europe projects. See the information in the Horizon Europe Programme Guide.
3. Other Eligible Conditions
In order to achieve the expected outcomes, and safeguard the Union’s strategic assets, interests, autonomy, and security, it is important to avoid a situation of technological dependency on a non-EU source, in a global context that requires the EU to take action to build on its strengths, and to carefully assess and address any strategic weaknesses, vulnerabilities and high-risk dependencies which put at risk the attainment of its ambitions. For this reason, participation is limited to legal entities established in Member States, Iceland and Norway and the following additional associated countries: Canada, Israel, Republic of Korea, New Zealand, Switzerland, and the United Kingdom. In addition, entities established in third countries which may become associated to Horizon Europe during 2026 and 2027 may be eligible to participate in this topic if the third country is identified for this topic as an eligible country in the List of Participating Countries in Horizon Europe at the time of submission of the application[[See the List of Participating Countries in Horizon Europe available at https://ec.europa.eu/info/funding-tenders/opportunities/docs/2021-2027/common/guidance/list-3rd-country-participation_horizon-euratom_en.pdf.]]. In any case, the association agreement to the Programme must apply by the time of the signature of the grant agreement.
For the duly justified and exceptional reasons listed in the paragraph above, in order to guarantee the protection of the strategic interests of the Union and its Member States, entities established in an eligible country listed above, but which are directly or indirectly controlled by a non-eligible country or by a non-eligible country entity, may not participate in the action unless it can be demonstrated, by means of guarantees positively assessed by their eligible country of establishment, that their participation to the action would not negatively impact the Union’s strategic assets, interests, autonomy, or security. Entities assessed as high-risk suppliers of mobile network communication equipment within the meaning of ‘restrictions for the protection of European communication networks’ (or entities fully or partially owned or controlled by a high-risk supplier) cannot submit guarantees.[[ The guarantees shall in particular substantiate that, for the purpose of the action, measures are in place to ensure that: a) control over the applicant legal entity is not exercised in a manner that retrains or restricts its ability to carry out the action and to deliver results, that imposes restrictions concerning its infrastructure, facilities, assets, resources, intellectual property or know-how needed for the purpose of the action, or that undermines its capabilities and standards necessary to carry out the action; b) access by a non-eligible country or by a non-eligible country entity to sensitive information relating to the action is prevented; and the employees or other persons involved in the action have a national security clearance issued by an eligible country, where appropriate; c) ownership of the intellectual property arising from, and the results of, the action remain within the recipient during and after completion of the action, are not subject to control or restrictions by non-eligible countries or non-eligible country entity, and are not exported outside the eligible countries, nor is access to them from outside the eligible countries granted, without the approval of the eligible country in which the legal entity is established.]]
