Why you should apply today

PQ-REACT Open Call #1-Develop, is inviting applicants who can develop and provide innovative solutions to address the specific challenges of PQ-REACT in terms of PQC computational complexity and energy efficiency.
Develop and submit your proposal, which will be tested in the project’s use cases.

PQ-REACT Use Cases:
There are 4 Use Cases that you can choose based on your expertise:

Smart Meters are usually provided with limited processing and/or storage capabilities, and also typically deployed in environments with low bandwidth. With this kind of constraints upgrading some of the functionalities protected by Asymmetric Crypto to rely Post-Quantum Crypto algorithms can lead several problems.

Specifically, the test scenario is focused on the Firmware Update functionality. In some real deployments the FW is protected by means of Elliptic Curve Digital Signatures (e.g.: NIST P-256 Curve) just to address the limitations introduced above, and the pilot’s target will be to measure/address the challenges raised by migrating to Post-Quantum Digital Signature Algorithms (or mixed classical/PQC deployments).

Leveraging PQC and QKD hybridization approaches related to 5G and their evolution to 6G architectures. PQ-REACT will investigate their application to significant use-cases, especially related to authentication, and protection mechanism for the network infrastructure, addressing the security and performance requirements in highly-pervasive, critical networked environments.

Test and validation of innovative services/apps that use PQC algorithms, in terms of various parameters like CPU, memory, power consumption, bandwidth, etc., over a virtualized infrastructure via a monitoring tool provided by the project. The algorithms may be NIST approved or submitted in the NIST Post-Quantum Cryptography Standardization Call for proposals.

Practical validation and assessment of the resilience of new applications/solutions (including loTs) using PQC techniques, exploiting the capabilities of an HPC (High Performance Computer) or QC (Quantum Computer) via a suite of tools (C++/Python/Qrisp). Additional tools like, Quantum Approximate Optimization Algorithm (QAOA), Shor’s algorithm, algorithmic primitives (e.g., quantum Fourier transform (QFT), quantum phase estimation (QPE)) and solving QUBO problem instances with QAOA are available in Qrisp.

The Open Call numbers
Use Cases
Per Pilot
Who can apply?

Small and medium-sized enterprises and startups that focus on developing innovative solutions related to PQ-REACT use cases. 
SME will be considered as such if complying with the European Commission Recommendation 2003/361/EC16 and, the SME user guide17

One application is accepted per research group. It’s important to note that within a department, multiple research groups exist, and while different groups from the same department can apply, it’s crucial that individuals are not concurrently members of multiple research groups to ensure equitable allocation of resources and dedication to their respective research pursuits.

Non-profit organizations and foundations with experience in applications development.

Important note

In this Open Call, only one application per SME is allowed. For Universities and research centers, only one application per research group is allowed. Therefore, no multi-participation is allowed in this Open Call. No applications in consortia are also allowed in this call. Each application must be sent by a sole entity.

This call does not allow applications in consortia. Each application must be sent by a sole entity.

  • EU member states and Horizon Europe associated countries

Only applicants legally established/resident in any of the following countries (hereafter collectively identified as the “Eligible Countries”) are eligible for funding:

The Member States (MS) of the European Union (EU), including their outermost regions.

Horizon Europe associated countries: according to the updated list published by the EC on the submission date of the proposal.

How to apply:


Check the eligibility criteria. If you fulfill them, then you are one step closer to submitting your application.
