10:10 → 10:25 Task Review

Task 4.1 - Theoretical and experimental investigation of quantum foundations.
Institutions: SNOLAB, UoA, INFN, CNRS
This task is led by INFN-LNF and Adelaide includes the design and implementation of experimental setups to test quantum collapse theories, wave function collapse models, and quantum gravity effects using data from quantum sensors. These secondments will provide hands-on training to researchers on advanced quantum detection techniques and theoretical modelling. The researchers will conduct collaborative analysis of experimental data after the secondment to ensure knowledge dissemination among all partners.

Task 4.2 Development and testing of quantum detectors.
Institutions: SNOLAB, UOA, INFN
This task is led by INFN-LNGS and involves the evaluation and underground running of advanced sensor technologies based on quantum circuits and novel materials to test theories of low mass dark matter. Secondments will include detector testing and evaluation. Promising prototype detectors will be deployed in deep underground infrastructure at SNOLAB and/or LNGS and SUPL (laboratory of which the University of Adelaide is a member) for low background evaluation and dark matter searches. The groups will evaluate the data after secondments to utilize underground data to improve the dark matter sensitivity and improve future detector design.

Task 4.3 Noise characterization and mitigation in Quantum Technologies.
Institutions: SNOLAB, INFN
This task is led by SNOLAB and involves the development and underground running of advanced qubit technologies based on superconducting quantum circuits. Secondments will include qubit deployment, test, and evaluation, which will transfer quantum processor operational experience across the consortium. Quantum processors will be deployed in deep underground infrastructure at SNOLAB for low background evaluation and to study the impact of correlated errors from ionizing radiation. The groups will evaluate the data after secondments to utilize underground data to improve the understanding of this critical source of qubit errors and incorporate this knowledge into future quantum computer concepts.

Task 4.4 Collaboration, dissemination and reintegration activities.
Institutions: SNOLAB, UOA, INFN, CNRS.
This task will be collaborative between the four institutions involved in this work package. SNOLAB, INFN and the University of Adelaide will organize interdisciplinary training workshops during secondments to facilitate knowledge exchange on quantum foundations, dark matter, quantum sensors, and quantum processors. Knowledge will be shared with participating institutions and major results will be published in academic literature and conferences to inform the broader research and device development communities. Outreach and public engagement activities will be utilized to amplify the societal impact more broadly. The organization of a workshop on quantum foundations and quantum technologies in underground laboratories is planned the 1st year at M12 (see WP5/D5.9).

10:25 → 10:35 Deliverables Review

D4.1: Report on R&I advances in quantum foundations -M46: A comprehensive report detailing experimental findings on quantum collapse theories and quantum gravity effects, produced collaboratively through secondments and post-secondment analysis.

D4.2: Prototype quantum detector for low-mass Dark Matter and performance assessment -M6: Reports on modern prototype quantum sensors evaluated during secondments, with documented performance and sensitivity metrics. Training documentation and guidelines for future detector development and deployment.

D4.3: Report on noise mitigation framework for Quantum Technologies - M42: A technical report and toolkit developed collaboratively during secondments, outlining methods for identifying and mitigating noise sources in quantum detectors and qubits

D4.4: Collaboration and knowledge dissemination outputs: Reports and proceedings from training workshops and secondments, highlighting key outcomes and innovations. Reports will be delivered annually. Final report in M47. Peer-reviewed publications, conference presentations, and public engagement materials showcasing advancements in quantum science and technology. A reintegration report summarizing knowledge transfer and the integration of skills and technologies into partner institutions post-secondments.
