Fostering quantum developments in the European high-energy physics community and beyond.
Info
Through its Quantum Technology Initiative, CERN acts as an "honest broker" — an international, open, and neutral platform — across the CERN Member States and the HEP community worldwide, to foster innovative ideas in the high-energy physics field and beyond. Building on CERN’s unique expertise and strong collaborative culture, we aim to: - build, support, and promote multi-disciplinary collaborations, complementing the ongoing national and international activities, - co-develop quantum-technology expertise with academic, research and industrial partners, exchanging knowledge and innovation, - establish a joint research programme, exploring potential applications of quantum computing and algorithms, quantum theory and simulation, quantum sensing, metrology and materials, quantum communication and networks, - set up education and training activities, growing competence and knowledge for the new generation of scientists, from high-school students to senior researchers.

Our quantum algorithm team published another important contribution to the field. Read the extended post from our algorithm’s coordinator Michele Grossi
Happy to finally celebrate the publication of our work in #PRXQuantum — almost one year after the first version of the manuscript. This paper evolved substantially throughout the review process, thanks to a truly stimulating and constructive interaction with the referees. The final result is much deeper than we originally thought. At the core of the paper is a question that is becoming increasingly important for variational quantum algorithms: 👉 how is the interplay between noise and unitary layers in the emergence of loss concentration?What can we learn from that? We employ non-negative matrix theory to derive a general expression to show that mixed configuration of ideal and noisy qubits, as well as a partial realization of error correction, could potentially outperform purely ideal or purely noisy systems in terms of variance and highlights novel properties. This allows us to derive: ⚛️ exact variance expressions in the deep-circuit regime, ⚛️ controlled convergence bounds for shallow and deep circuits, ⚛️ and a unified description of how noise and circuit structure jointly shape trainability. ‼️ One of the most interesting results is the emergence of a noise-induced absorption mechanism, a phenomenon completely absent in purely unitary dynamics. This provides a new physical picture of how noise modifies the concentration behavior of variational landscapes. Lastly, we focus on the relevant aspect of contractivity and alignment between invariant subspaces to derive BP-free QResNets as stochastic unravelings of sufficiently weak noise maps.

🚀 New preprint out: Physics inspired quantum algorithm for QCD splitting functions One of the most fascinating developments in recent years is the growing interplay between quantum information theory and high-energy physics. This work sits exactly at that interface. In this paper, we explore how a quantum circuit model can be used to encode and reproduce one of the key ingredients of QCD dynamics: splitting functions, which govern parton evolution and ultimately shape the jet structures observed at colliders. Instead of approaching the problem as a direct “quantization” of a classical algorithm, we follow a more physics-driven route: ⚛️ build a quantum-native primitive inspired directly by the branching structure of QCD. The interesting part is that this is not just a toy construction. The proposed framework: captures physically relevant multi-prong jet topologies, defines a primitive with a provable and natural scaling structure, and is validated on real experimental collider data. This is particularly exciting because multi-prong structure identification is a central challenge in modern collider physics, especially in increasingly complex environments where correlations and hierarchical emissions become difficult to model efficiently with standard approaches. More broadly, this points toward a deeper idea: 👉 quantum computing may become not only a computational accelerator for HEP, but also a new framework for expressing the structure of quantum field theoretic phenomena themselves. Really excited about the possibilities opened by this direction, especially at the intersection of: 🔹 quantum information 🔹 collider phenomenology 🔹 jet physics 🔹 and quantum algorithms for fundamental science.

🌟 🚀 Spotlight on CERN’s quantum technologies during 2025 What better moment than World Quantum Day to read about CERN’s knowledge transfer 2025 highlights in the quantum domain! Through the CERN Quantum Technology Initiative (QTI), the Laboratory is exploring how it could potentially benefit from emerging quantum technologies and also support quantum tech companies in their developments. Emphasising the importance of collaboration to maximise the impact of the QTI, CERN is partnering with key players in the quantum sector to establish co-development opportunities with industry and research institutes. During 2025, CERN grew fruitful innovation partnerships and helped develop technology applications in the quantum domain. For example: ID Quantique (IDQ) has incorporated the PicoTDC ASIC, a time-to-digital converter originally developed by the Electronic Systems for Experiments group at CERN, into their flagship time controller. The resulting technology combines CERN’s expertise in ultra-precise time-to-digital conversion with IDQ’s leadership in quantum detection systems, enabling cutting-edge performance for scientific and industrial applications. ➡️ https://lnkd.in/d2vQwYeZ 🗣️ CERN hosted the Quantum Business Community (QBC) Summit, the annual gathering of the European Quantum Industry Consortium (QuIC), bringing together over 100 participants from industry and research. Discussions focused on strengthening Europe’s strategic position in quantum technologies. The summit highlighted CERN’s role as a neutral hub for open dialogue, collaboration, and knowledge exchange across the quantum ecosystem. ➡️ https://lnkd.in/d59_PYTw A consortium of academic, industry, and public partners comprising the University of Geneva (UNIGE), CERN, Haute école du paysage, d'ingénierie et d'architecture de Genève - HEPIA , ID Quantique, ROLEX and the Cantonal Office for Information Systems and Digital Technology launched the Geneva Quantum Network, the city’s first quantum communication infrastructure. Built on existing fibre networks, it connects key institutions to enable large-scale experiments in quantum communication, metrology, and synchronisation. The initiative positions Geneva as a hub for real-world quantum technology development and collaboration. ➡️ https://lnkd.in/ds4RF9YF Thanks to QTI’s Sofia Vallecorsa, Michele Grossi, Maurizio Pierini, Edoardo Martelli and Amanda Díez Fernández for coordinating CERN’s quantum activities and partnerships, to CERN technical contacts David Porret and Jorgen Christiansen (for their collaboration with ID Quantique and to Annick Teepe, Adam Wujek, Maciej Lipinski and Javier Serrano for their contributions to the Geneva Quantum Network).

🚀 New preprint out! 👉 https://lnkd.in/dY4TXMsH As #quantumcomputing matures, one thing is becoming clear: the future is #hybrid. From variational algorithms to circuit cutting, error correction... many applications rely on tightly coupled quantum and classical resources — and orchestrating these workflows is now a key challenge. In our latest work, we explore how #Kubernetes can serve as a cloud-native orchestration layer for hybrid quantum–classical pipelines. We show how complex, multi-stage workflows can be executed across CPUs, GPUs, and QPUs, with dynamic scheduling, scalability, and full observability built in. 👉 We introduce a cloud-native framework based on Kubernetes to orchestrate hybrid quantum–classical pipelines. 🔹 A unified orchestration layer for CPUs, GPUs, and QPUs 🔹 Multi-stage workflows defined as DAGs (via Argo Workflows) 🔹 Dynamic, resource-aware scheduling (via Kueue) 🔹 Built-in monitoring and observability (Prometheus + Grafana) We demonstrate the approach on a distributed circuit cutting workflow, showing how complex hybrid pipelines can be executed seamlessly across heterogeneous resources. ⚖️ Key message: this is not about replacing Slurm. Slurm remains essential for HPC batch workloads, but Kubernetes offers a powerful complement for multi-stage, dynamic workflows typical of modern quantum applications. 👉 The real opportunity lies in combining both worlds. Excited to contribute to bridging HPC and cloud-native approaches for next-generation quantum computing. 🙏 Huge thanks to all collaborators — this has been a truly interdisciplinary effort!
