Mindfulness Meditation group practice every Wednesday evening at Unity of Gaithersburg. Mindfulness practice is not about achieving some special state of mind; it is more about noticing the experience you are having without trying to change it. This interesting video suggests why you might sit and watch your mind wander off. https://www.youtube.com/watch?v=DmmBF8eTl18 This noticing tends to shift your nervous system from a 'fight-or-flight' state to a more relaxed and receptive state. In this receptive mental state, you begin to see your own experience differently and, over time, see other people and the world differently. Also, it is good for you: "the effect of regular meditation on the cortex was so profound that fifty-year-old meditators had a prefrontal cortex that looked like that of a twenty-five-year-old" [https://www.amazon.com/gp/product/B07PLRZVTT](https://www.amazon.com/gp/product/B07PLRZVTT) Here is an interesting and funny take on meditation by Ajahn Brahm: [https://www.youtube.com/watch?v=TR60RRmXeYs](https://www.youtube.com/watch?v=TR60RRmXeYs). If you arrive on time, there will be an introduction at the beginning, if you arrive late, find a chair and join us. There will be some discussion after. This is a free event, but contributions to the church's expenses are welcome. You can just show up this Wednesday or subsequent Wednesdays.

Date: June 7 2026 Sunday 10:00 am - Noon EDT Full title: Machine Learning for Reliable Quantum Computing: An Algorithm–Hardware Co-Design Perspective Summary: Reliable quantum computing requires co-design across the full stack, including algorithm structure, compilation, and execution, rather than isolated optimization of any single layer. This talk presents a unified framework in which these layers are jointly optimized under realistic hardware constraints. Structure-aware compilation exploits algorithmic interaction graphs to reduce circuit depth; joint optimization across mapping, term ordering, and algorithm parameters yields significantly improved success probability; and execution-layer analysis reveals that error mitigation effectiveness depends critically on circuit symmetry and native gate choice. While demonstrated on superconducting quantum processors, the underlying co-design principles are potentially transferable across architectures. Building on this foundation, the talk highlights machine learning as the key enabler for closing the feedback loop: data-efficient, parameterized noise models learned directly from workload execution data achieve substantially improved predictive fidelity over vendor models without the overhead of dedicated characterization. These insights situate the co-design perspective within the emerging framework of quantum deep learning. In this broader setting, the talk also presents an operational definition, a unifying taxonomy, and a benchmarking protocol grounded in explicit resource contracts. Speaker: Dr. Yanjun Ji has an interdisciplinary research background in Physics and Computer Science. In 2020, she completed my Master's degree in Theoretical Physics at Saarland University. In 2024, she earned her Ph.D. in Computer Science at the University of Stuttgart. She is currently a postdoctoral researcher at Forschungszentrum Jülich. She is committed to interdisciplinary research at the cutting-edge convergence of quantum computing and artificial intelligence. Her research encompasses both foundational theoretical investigations and the development of practical applications, aiming to serve society and benefit humanity. Moderators: Dr. Pawel Gora, CEO of Quantum AI Foundation [Quantum AI Foundation](https://www.qaif.org/ "https://www.qaif.org/") Dr. Sebastian Zajac, member of QPoland [QPoland - QWorld](https://qworld.net/qpoland/ "https://qworld.net/qpoland/")
