Looking for a new skill? Want to seem mysterious when people ask about your hobbies? Enjoy puzzles? Lock picking might be right for you! Is this legal? Yes! Is it fun? Yes! The meeting is very casual, come and go as you please. We meet in the upstairs area of Board Room. No payment, skills, tools, or RSVP necessary. If you can make small precise movements with your hands, you can learn to pick locks. Introductory talk at 7pm. All are welcome. We meet in a bar but minors are allowed to attend. We are not in a private room; parental discretion advised. If you are a minor or are responsible for one who's attending, please email the organizer in advance at chapter-DC@toool.us Open invite; bring friends! We are the DC chapter of TOOOL.

Please do not arrange to play earlier than the scheduled start time UNLESS you are able to stay till the end of the event, we do not want people leaving early and creating uneven numbers. Hello members, Tennis has become much more popular since the pandemic started and court space has been harder to come by. Following these simple rules will help everyone get the most out of MoCo Topspinners Meetup. • If you RSVP for an event, please attend that event or cancel at least two hours before the event starts. Members that no-show will receive one warning then will be benched (suspended) from events for two weeks. Three no-shows can result in a permanent ban. (No-shows create uneven numbers and prevent folks on the waitlist from playing. Please do your part to un-RSVP as soon as you know that you cannot attend an event.) • Members must have a way to communicate with organizers and hosts. This can be through the Meetup app messages or by providing other contact info. • Any member can ask a host or organizer to have their skill rated for event attendance purposes. You will not be allowed to participate in events higher than your NTRP rating. (We may try to limit numbers or have multiple events on a given day to accommodate players of different skill levels and also to help alleviate the court availability problem). • All members shall conduct good sportsmanship and be courteous to other members at all times. • Sexual harassment, racism, sexism or any kind of intolerance will not be tolerated and will result in the permanent ban from the group. • If member receives three warning infractions, the member will be suspended from the Meetup for a period of one month. If a member is suspended twice (six warnings), that member will be permanently banned and any membership dues will then be forfeited. • If you are scheduling to play with others outside of a MoCo Topspinners event, and you know that there is a MoCo Topspinners event scheduled for that day at that time, please try to use courts other than the courts where the event is scheduled, or move your time so that it does not conflict with the Topspinners event. For a list of complete rules and definitions you can see the MoCo Topspinners front page. If you have questions, don’t hesitate to contact us. We are hoping for a fun season but we may have to wait for courts and leave earlier than we are used to. Please be patient as we adjust to this new normal and try a few different things that will hopefully help the situation. Happy playing! If you would like to attend this event you must be a of minimum 3.0 level. USTA guidelines prior for signing up for the Meetup: https://assets.usta.com/assets/1/15/ExperiencedGuidelines_02142011_V2pdf.pdf Singles and doubles game play flexible depending on court availability. If you have any questions, please feel free to drop the group organizers a message. Looking forward to a great 2021 season- see you on the courts! • What to bring Tennis Balls and Racket, Water.

**👉 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.

This group was originally started by Chad Keith who created and hosts a podcast by the same name in Charlotte, NC. I am hoping to continue his legacy here in NoVa as I recently moved to this area. This group is all about finding community around self-improvement and exchanging ideas on how to be your best self and get the most out of life. This group is for anyone who is interested in overcoming average in all areas - career, ambitions, relationships, hobbies, health, everything. I am so excited to meet driven individuals in the NoVa area so please reach out if you have any questions at all. EVERYONE is welcome so please sign up for an upcoming meetup!

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/")
