Researchers at Leibniz IPHT working on the QRC-4-ESP project reported a new approach for measuring the coherent dynamics of a superconducting qubit embedded in an open waveguide. By studying how the qubit interacts directly with propagating microwave photons, the team demonstrates a powerful method for probing quantum coherence in an open quantum system. 🔬🌊 The work provides valuable insights into light–matter interactions at the quantum level and advances our ability to ch

A new study, “Vanadium photoluminescence in 3C-SiC”, sheds fresh light on the optical properties of vanadium defects in cubic silicon carbide (3C-SiC) – a material attracting growing interest for quantum technologies. 🔬💎 Combining advanced spectroscopy, materials growth, and theoretical modelling, the researchers at LiU working on the QRC-4-ESP project investigate the photoluminescence signatures of vanadium centres and provide important insights into their electronic struc

🚀 Two recent papers in Chaos journal by Loughborough University researchers highlight exciting advances in both photonic and quantum reservoir computing. 📄 Unwrapping photonic reservoirs: Enhanced expressivity via random Fourier encoding over stretched domains demonstrates that deliberately “over-wrapping” optical phase information beyond its conventional 2π range can improve computational performance. By exploiting nonlinear interference and synthetic frequencies, the auth

From 8–12 June 2026, Budapest hosted the international conference Defects in Solids for Quantum Technologies (DSQT 2026) at the Faculty of Science of Eötvös Loránd University (ELTE). The conference brought together leading theorists and experimentalists from around the world to discuss the latest advances in solid-state qubits, quantum emitters, quantum sensing, and materials for next-generation quantum technologies. The event also placed a strong emphasis on fostering interd

In early June, researchers, PhD students and experts from across Europe gathered at Eötvös Loránd University (ELTE) in Budapest for the QUEST and QRC-4-ESP Summer School on New Directions in Quantum Computing. The event focused on three rapidly advancing areas of quantum information science: Measurement-Based Quantum Computing, Quantum Machine Learning and Quantum Reservoir Computing. 📚 Participants attended lectures and discussions covering: • Quantum Reservoir Computing a

1. Your recent work touches on quantum computing and quantum reservoir computing - what research problem are you most focused on right now, and what makes it especially interesting from your perspective? Recently I’ve spent a lot of time on the question of computationally useful structure of quantum subsystems. Certain types of quantum systems generate useful subsystem structure for information processing, while others do not, and understanding the reasons behind this diffe

🔍 Layered semiconductors are attracting growing interest for quantum technologies such as photonics, sensing, and spin-based devices. So far, most research has focused on artificially engineered materials . In contrast, natural layered materials - like talc - have been largely overlooked, even though they offer several important advantages. 🌿 Talc and related silicate materials have a wide, direct bandgap, very few optically active defects, and a low density of nuclear sp

Trisha Roy, Aalto University PhD Researcher 1. Could you briefly introduce yourself, your PhD research focus, and how you became involved in this project? I’m a first-year PhD student at Aalto University in the MSP group, working on quantum reservoir computing for time-series prediction. In simple terms, I try to make a quantum circuit predict the future of chaotic systems - and then I study exactly when and why it starts failing. My current focus is on how tunable non-Cliffo

🔬 Researchers working on the QRC-4-ESP project - Moein Ivaki, Matias Karjula and Tapio Ala-Nissilä - have recently published new results in Quantum Physics 👉 https://arxiv.org/abs/2510.18623 ⚙️ The paper introduces a novel approach to designing quantum machine learning (QML) systems that are both expressive and trainable . Using a random circuit model, a single control parameter (probability p ) smoothly tunes the system from classically easy dynamics to quantum-univers

Moein Ivaki, Aalto University Postdoc Researcher 1. Could you briefly introduce your postdoc project - what core question you’re tackling this year, and why it matters? I’m a postdoc in the MSP group at Aalto University’s Department of Applied Physics. My project asks a simple but demanding question: which quantum systems are actually good learners for temporal tasks? I study how structural properties - nonlocal correlations, complexity, disorder, symmetries, noise - shape p

Principal Investigator Alexandre Zagoskin from the QRC-4-ESP project, shared his insightful experience at the recent UK Quantum Showcase in London. The event was a hub of innovation and collaboration, bringing together a diverse group of professionals passionate about quantum advancements. https://lnkd.in/eT6qyq_S #QuantumResearch #Innovation #UKQuantumShowcase

Dr. Wendy Otieno, Loughborough University Postdoc Researcher 1. What first sparked your interest in quantum research, and how did it lead you to join the QRC-4-ESP project? Numerically solving Schrödinger’s equation for quantum systems like particles in finite and infinite potential wells first sparked my interest in quantum research. Through this process, I developed a deep appreciation for the elegant yet challenging mathematical structures that underpin quantum systems.
