**👉 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.

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/")

Let’s talk about how you use AI, what you love and hate about it, learn from others and connect with your tribe!

**NEW MEMBERS or 1st TIME EVENT GO-ERS** Before attending your first event, please take a moment to understand how our dinners work and what we ask of members. → **[Learn how DC Metro Dining works](https://tinyurl.com/Landing-Page-DC-Metro-Dining)** → **[Ensure Group Notifications are Setup (Announcements + In on Waitlist/Attending List)](https://app.tango.us/app/workflow/Enable-Meetup-Email-Notifications-3a85109614fc4907940503d096331392)** **RSVP CUTOFF (i.e. Final Change Your Mind if Registered YES)** → **RSVP Cancellation Cutoff for this Event is Sunday 10a, 6/6**. (*Late Cancel applies after this, repeat occurrences can impact membership*) Let’s head to upper Northwest DC for an Indian dinner at Masala Art in Tenleytown, a long-running neighborhood favorite known for refined North Indian cuisine and regional specialties. The restaurant was founded by chef Surinder Singh, formerly of Heritage India, and continues to maintain a strong reputation for consistent execution and depth of flavor. **FOOD**: Masala Art focuses on North Indian cuisine with a mix of classic curries, tandoori dishes, and harder-to-find regional specialties, vegetarian & GF friendly. Recent diners frequently highlight the Railway Lamb Curry, lamb korma dishes, garlic naan, and vegetarian items such as baingan bharta and okra preparations. Tandoori items and biryanis are also consistently well reviewed, with many diners noting balanced spice levels and strong flavor without excessive heaviness. The menu supports a wide range of preferences, including vegetarian-friendly selections and several richer meat-based dishes. Expect traditional Indian desserts and a full bar with wine, cocktails, and beer available. Most members should expect total spend to land roughly in the 40 to 70 dollar range, depending on ordering style & beverage participation. → **Explore Masala Art's menu (please note the 3% service charge, their way of defraying increasing costs):** **[https://masalaartdc.com/washington-dc-tenleytown-american-university-park-masala-art-food-menu](https://masalaartdc.com/washington-dc-tenleytown-american-university-park-masala-art-food-menu)** **SPACE**: Comfortable and intimate dining room with warm décor and a quieter neighborhood feel compared to downtown DC dining corridors. Expect moderate noise levels and a more relaxed pace on a Saturday evening. → **Visit the restaurant site**: **[https://masalaartdc.com](https://masalaartdc.com)** * Tax/Tip combo is our required 30% tax/tip policy (see the FAQs for more details). * Limited to 8 slots. See you there! JoeN **CLOSEST METRO**: * **Tenleytown–AU station (Red)** is the closest stop. Quick walk (exit on Tenleytown EAST (same side as Whole Foods) walk south along Wisconsin Ave & cross over Albermarle St NW). The walk is a quick 3–5 minutes based on routed walking directions and traffic signals. * For directions using the Metro, try using the Plan a Trip feature at the WMATA website ([click on your preferred Metro station](https://www.wmata.com/rider-guide/stations/index.cfm) then at the Station page level click "Plan a Trip". **PARKING**: Street parking and several public parking garages are available throughout Tenleytown. Weekend evening parking is generally easier here than in central DC neighborhoods, though nearby retail activity can still affect availability. Members may also want to check parking apps such as SpotHero and Parking Panda for discounted garage reservations and advance booking options nearby. Plan accordingly. ***Attendance Notes:*** * **If you RSVP “YES,” please commit to showing up***. With 5,400+ members and limited seating, we can’t afford no-shows. It’s not fair to other members or to our relationship with the restaurant.* * **New Members / 1st Timers: Trying to get a slot?** Join the Waitlist and check back frequently: spots (*often open up before Noon on the day of the event. You may also receive midweek confirmation emails to reconfirm your RSVP, so please check your Meetup DMs inbox).*\*\* * **Billing Reminder - Add 30% for tax and tip to your food and drink total.** This is part of our group’s expectations and helps smooth out service with the restaurant. Looking forward to dining with you! JoeN

**The Behavior Gap: Where Products Win or Lose** Teams today have more data than ever, and yet many still struggle to understand why customers adopt, engage with, or abandon their products. Teams sprint, ship faster, and chase more signals… all while metrics stall and confidence drops. The missing piece isn’t more data. It’s often the behavioral insight between the metrics, explaining why the numbers move in the first place. Dashboards can tell you what customers did, but understanding why they did it (and how to influence what they do next) requires a deeper blend of insights. This session is about closing that gap. Drawing from real-world experience designing and scaling products as [ZoCo Design](https://zocodesign.com/)’s CEO, [Lacey](https://www.linkedin.com/in/laceypicazo/) will share how to cut through the noise and identify the insights that actually change behavior—moving people, and moving metrics. You’ll learn: * Why understanding customer behavior is a quant and qual challenge * How to spot the signals that actually predict behavior change * Where AI accelerates insight, and where it creates distraction * How to get meaningfully closer to customers, without adding more tools This talk reframes how to evaluate performance and identify what levers actually improve it, helping your team to make smarter bets with greater confidence. Every meaningful outcome is driven by behavior change. And when you know how to design for behavior, you stop guessing, and start building things that work. **About Our Speaker** [Lacey Picazo](https://www.linkedin.com/in/laceypicazo/) is the Founder and CEO of ZoCo, a healthcare product studio that turns complex, high-stakes ideas into products that drive real-world adoption. She partners with healthcare organizations to uncover critical care delivery insights, focus product strategy through behavior design, and build solutions that patients and providers actually use.
