**👉 Please [RSVP on Luma](https://luma.com/pubkey-aqxx)** Strategy holds more bitcoin than any other public company on earth, and along the way it's become one of the most talked-about, and most polarizing, names in both finance and Bitcoin. Join us at PubKey for a candid conversation with two people living inside that story: **CJ (Chaitanya Jain)**, Strategy's Head of Investor Relations, and **Ella Hough**, who leads Bitcoin advocacy at the company. ​ Moderated by **John Balkam**, CMO of [Sovreign](https://sovreign.io/?utm_source=luma), the discussion goes behind the headlines into what it's actually like to execute the Bitcoin Treasury playbook in real time. CJ and Ella will talk about working alongside leaders like executive chairman Michael Saylor and CEO Phong Le, navigating Strategy's role as a lightning rod for both believers and critics, and the personal convictions that brought them to the company. Expect a frank look at the strategy, the scrutiny, and the people behind the world's largest corporate Bitcoin bet. **👉 Please [RSVP on Luma](https://luma.com/pubkey-aqxx)** ​**About the Bitcoin District Initiative** This event was organized by The Bitcoin District Initiative, a 501(c)(3) nonprofit working to build a grassroots Bitcoin circular economy in Washington, DC through education, business onboarding, and community outreach programs.

**Tired of surface-level conversations?** Join us for *Ditch the Small Talk*—an evening of deep, real connection with strangers who are down to go there. We’ll meet in the grass in front of the cathedral, break into small groups, and draw questions from a deck of cards designed to spark vulnerable, honest conversations. How it works: Draw a card and ask a question. Listen. Don't coach or give advice without permission. Try to ask follow-up questions when people share. You can spend 1 minute on a question or 1 hour, just go with the flow. **If you show up late, please don't interrupt the speaker. Just sit down in a group of your choice and they'll bring you up to speed when whoever is talking finishes. Bring a blanket or chair if you don't want to sit in the grass. *** Rules*** 1. Don't debate politics 2. Keep what is shared in the group within the group 3. If you need to use your phone, step away from your group first

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/")

## 🤝 Host Information A co-hosted event by ProductTank Columbus & Women in Product Columbus 💡 About the Workshop AI adoption is stalling across organizations — not because of a lack of motivation or tools, but because it's fundamentally a behavior design challenge. This hands-on workshop applies proven Behavior Design models and methods to help you move from a vague organizational wish to boost AI adoption to 3-5 concrete, testable interventions you can act on starting tomorrow. Whether you're a product manager, on a product team, or just someone trying to get AI to actually stick at work, you'll leave with a clear picture of what's worth focusing on, what to ignore, and how to drive real, sustained adoption — no guesswork required. 🛠️ What to Bring Laptop: Fully charged and ready to go. AI Assistant: Have your favorite AI assistant pulled up. (Dom will be using Claude, but feel free to use whichever assistant you prefer!) 🍕 Logistics & Perks Food & Drink: Pizza and drinks provided! Parking: Plenty of free spaces available on-site. ###

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.
