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.

THIS CLASS IS OFFERED THROUGH CAPITAL PHOTOGRAPHY CENTER **PLEASE REGISTER WITH CAPITAL PHOTOGRAPHY CENTER, NOT MEETUP!** https://capitalphotographycenter.com/classes/class/2026-06-07-iphone-photography Learn to use the iPhone camera and the settings for creative image captures. Join Michael Koren at the National Gallery of Art and learn techniques for exposure, composition and focus. Tap into your creative side through smartphone photography. Using our iPhone cameras, we’ll explore the Museum's offerings from abstract sculptures, colorful paintings and wall hangings, to the architecture of the building as well. We’ll find endless photographic opportunities perfect for iPhone photography. We’ll start with the basics of learning to use the iPhone camera and review the settings for optimal image capture to pro tips and techniques that produce the best results. The number of photography apps available seems endless and can be very confusing when trying to choose what to purchase. Michael will cover one of the most exciting apps for image processing so you can achieve your artistic vision. This class is designed for users of iOS mobile devices. The app info will be included in your confirmation letter (the app is free). Topics include: • Proper techniques and settings for iPhone image capture • Tips and techniques for using the iPhone’s native camera • Learn exciting editing tools • Hands-on capture and editing • Image critique and feedback For more information about the Gallery, visit their website, https://www.nga.gov/index.html Participants will need to bring a fully charged iPhone. A charger is a good idea too as photos quickly drain the batteries. Questions can be directed to Marie Joabar at info@capitalphotographycenter.com. *** **THIS CLASS IS OFFERED THROUGH CAPITAL PHOTOGRAPHY CENTER** https://capitalphotographycenter.com/classes/class/2026-06-07-iphone-photography

It’s given me a whole new perspective. My intuition feels incredibly enhanced and my sense of awareness has expanded. I’ve never felt better than I do now!"- MM** **Each month on the first Sunday we will be coming together as a community for a Unique sound bath offering in Burke VA. Every month will be something new ranging from different chakra centered meditations, Gong Baths, and even unique themed meditations honoring the whales and elephants of our sacred Mother Earth.** **Bring your pillows, blankets, and yoga mats and snuggle into the comfort of the tranquil sounds. Feel free to sit, lay, or even stand! First-timers welcome.** **7:00 pm - Meditation Reception** ***\*\*Meditation in our sacred space will begin promptly at 7:30 pm. Please refrain from entering after 7:30 pm.\*\**** **7:30 - Doors Close & Meditation Begins** **8:30 - Meditation Ends** **Contemplative Conversation will follow after the collective experience is complete.** **Suggested energy exchange, sliding scale between $15 - $30.** **All proceeds go to support the Crystal Ashram 501(c)(3) non-profit.**

**MLK Library - Room 401D** Are we facing a crisis of truthfulness? Given our unique and diverse experiences and perspectives, is it still possible to reach a collective understanding of what is “true” and to form a basis for how we determine truth? And how can we actively seek and recognize what is true, beyond just relying on conventional wisdom, tradition, superstition, or our own personal beliefs? Truth is an anchor to reality, rooting us in the midst of chaos and providing direction for a path forward. But while access to information has greatly increased, it seems to be increasingly difficult to determine facts from opinions or falsehood. Far beyond just being a problem in politics, it seems to extend into almost every part of our society and cultures. Could our ability to discern truth depend in part on certain spiritual qualities like humility and detachment complementing our senses, our mind, and intellectual training? What is the relationship of truth to justice? Are there tools that can help us seek and find the truth not only as individuals but collectively as a society? Come join a different kind of conversation – one that welcomes every perspective in a search for the truths that unite us all – as we discuss the spiritual perspective offered by the Bahá’í Teachings on the spiritual solutions to seeking the truth. Join us for a lively discussion as we explore how to apply spiritual principles of finding collective truth to benefit our lives and our communities. *“Truth has many aspects, but it remains always and forever one.”* – Bahá’í Teachings **\*\*\* This event is free and open to all regardless of background or belief. Donations will not be accepted.**

*Note: this is a demonstration event only, you **will not** shoot you own images. However, if you bring your camera we can test it for compatibility with the studio lights.* Bondage elements can add an extra layer of emotion and artistry to your images. Sample images on the internet are however dominated by BDSM style shots that are often sexualized and emphasize the model being in distress. In this demonstration Rachel and I show ways to use bondage elements in an artistic way. We explore the types of accessories that work best in artistic images and the best way to photograph them. Our model is Rachel Adams, an internationally known fetish model with many years of experience in this genre.

In this free, 1 day event, you are going to Build stuff with us! And yes, there will be free food. So please RSVP for a head count!

Private Group. Closed to the Public Knowing ourselves and understanding our abilities is the first step toward wielding our gifts with control and accuracy. In subsequent classes we will verify and hone our talents with activities and discussion. These are hands-on workshops and participation is expected. The goal of our series will be to develop expertise in areas of particular interest such as mediumship, channeling, divination, healing and, etc.. Our ultimate directions will be determined by class members as we evolve. I look forward to sharing and discovering with you. - Cynthia
