The next #quantumtechnology is being prepared for #integration into the #supercomputers of the Leibniz Supercomputing Centre (LRZ): For the "Multicore Atomic Quantum Computing System" (MAQCS) project, the Garching-based start-up planqc is currently developing a quantum system based on neutral atoms that offers 1000 qubits for calculations. Development is supported by the Max Planck Institute of Quantum Optics (MPQ) as the third part of the consortium with planqc and LRZ. The scientific community hopes that this large number of #qubits will provide real added value in solving problems in areas such as materials science, pharmacology, finance, transport or in specialist disciplines in general that are extremely complex or cannot yet be calculated using the methods currently available. The #quantumcomputer developed in the #MAQCS project become available to select researchers later in the project – which runs until end of 2027 - and will also be integrated into the LRZ's high-performance computing infrastructure (HPC). This is the third type of quantum computing technology in the portfolio of the LRZ, after several quantum computers based on superconducting circuits from IQM Quantum Computers and a 20-qubit ion trap-based system from AQT Alpine Quantum Technologies. #futurecomputing, #quantum, #quantumcompouting, #IT4Science Munich Quantum Valley, Munich Center for Quantum Science and Technology, EuroHPC Joint Undertaking (EuroHPC JU), Quantum - the open journal for quantum science, Quantum Computing,

Key Experiment and Quantum Reasoning | Article by Moritz Waitzmann, Kim-Alessandro Weber, Susanne Wessnigk and Ruediger Scholz https://lnkd.in/eqyaFrGt Leibniz Universität Hannover; MDPI #physics #education #quantum #experiment This article belongs to the Special Issue: Teaching and Learning Quantum Theory and Particle Physics https://lnkd.in/gfrPyezT #Abstract For around five decades, physicists have been experimenting with single quanta such as single photons. Insofar as the practised ensemble reasoning has become obsolete for the interpretation of these experiments, the non-classical intrinsic probabilistic nature of quantum theory has gained increased importance. One of the most important exclusive features of quantum physics is the undeniable existence of the superposition of states, even for single quantum objects. One known example of this effect is entanglement. In this paper, two classically contradictory phenomena are combined to one single experiment. This experiment incontestably shows that a single photon incident on an optical beam splitter can either be reflected or transmitted. The almost complete absence of coincident clicks of two photodetectors demonstrates that these two output states are incompatible. However, when combining these states using two mirrors, we can observe interference patterns in the counting rate of the single photon detector. The only explanation for this is that the two incompatible output states are prepared and kept simultaneously—a typical consequence of a quantum superposition of states. (Semi-)classical physical concepts fail here, and a full quantum concept is predestined to explain the complementary experimental outcomes for the quantum optical “non-waves” called single photons. In this paper, we intend to demonstrate that a true quantum physical key experiment (“true” in the sense that it cannot be explained by any classical physical concept), when combined with full quantum reasoning (probability, superposition and interference), influences students’ readiness to use quantum elements for interpretation.

Scientists at our Max Planck Institute for Intelligent Systems together with a team at ETH Zurich developed a robotic leg powered by electro-hydraulic artificial muscles known as HASELS. Inspired by living creatures, the leg jumps across different terrains such as grass, pebbles – even rocks – in an agile and energy-efficient manner. Plus, the artificial muscles are self-sensing, allowing the entire leg to detect collisions with obstacles and overcome them. More so, the leg uses up almost no energy when holding still and shows no observable temperature change – so very different to electric motors which would heat up. This innovative leg is a Max Planck ETH Center for Learning Systems research project.

How do atoms and molecules behave in particular materials or at different temperatures? Which calculations and models can be used to find this out? How can #DataScience, #AI, and #MachineLearning help advance this field of research and drive forward interdisciplinary research? The recently opened Atomistic Modeling Center at TUM addresses these and many more questions. Through the microscopic insight atomistic modeling provides into molecules and materials, AMC facilitates technological developments in core research areas at TUM, such as sustainable energy conversion, quantum materials, or drug discovery.    "This new initiative on atomistic modeling at TUM provides a great opportunity to fertilize highly interdisciplinary research work across its schools and establish closer links to industry partners, providing a unified scope and agenda for collaborative research," said David Egger, executive director of the new Atomistic Modeling Center.

📢 Welcome to read the Editor's Choice Paper “A Full-Body Relative Orbital Motion of Spacecraft Using Dual Tensor #Algebra and Dual Quaternions” by Prof. Dr. Daniel Condurache. This paper proposes a new non-linear #differentialequation for the six degrees of freedom (6-DOF) relative rigid bodies motion. A representation theorem is provided for the 6-DOF differential equation of motion in the arbitrary non-inertial reference frame. The problem of the 6-DOF relative motion of two spacecraft in the specific case of Keplerian confocal orbits is proposed. The result is an analytical method without secular terms and singularities. Tensors dual algebra and dual quaternions play a fundamental role, with the solution representation being the relative problem. Furthermore, the representation theorems for the rotation and translation parts of the 6-DOF relative orbital motion problems are obtained. 🔗 https://buff.ly/3RGwMqL #MDPIOpenAccess #ComSciMath_Mdpi

Model robustness for feedback stabilization of open quantum systems by Nina Hadis Amini Abstract: This paper generalizes the results in [30] concerning feedback stabilization of target states for N-level quantum angular momentum systems undergoing quantum non-demolition measurements (QND) in absence of the knowledge about initial states and parameters. Here we consider multiple measurement operators and study the stabilization toward a chosen target subspace which is a common eigenspace of measurement operators. Under the QND conditions, we show that this analysis provides necessary tools to ensure feedback stabilization based on a simplified filter whose state is a N-dimensional vector. A numerical analysis has been proposed in [18]. This paper provides a complete proof for the use of a simplified filter in feedback stabilization. This has important practical use as the dimension of quantum systems is usually high. This paper opens the way toward a complete proof concerning the robustness of a stabilizing feedback with respect to approximate filters, which is lacking.

🤖 How can artificial muscles transform the future of robotics? At the Soft Robotics Lab at ETH Zurich, we believe that a new design paradigm centered around nature’s musculoskeletal architecture will lead to adaptive, safe, and versatile robots. This approach could revolutionize how robots operate in dynamic environments, with applications ranging from soft robotics to human-centric systems. Our latest research, published in Nature Communications, is a significant step toward that vision. We have developed a musculoskeletal robotic leg powered by electrohydraulic artificial muscles, which can jump, adapt to uneven terrains, and perform high-speed movements—all while being incredibly energy-efficient. Highlights: • ⚡ Energy Efficiency: Significantly reduces energy consumption compared to traditional motor-driven systems. • 🦿 Agility and Adaptability: Easily adjusts to varying terrains without complex sensors. • 🚁 Future Applications: From soft robotics to rescue operations, the potential is vast. This project was made possible through the collaboration with the Max Planck Institute for Intelligent Systems, led by Robert Katzschmann and Christoph Keplinger, and co-authored by the co-first authors, Thomas Buchner and Toshihiko Fukushima. 🔗 Read the full ETH Zurich news article here: https://lnkd.in/em6_gcqz 📄 Curious to dive deeper?
