Welcome to our new home at the historic Tivoli Theater! Please check our details for access to the space on [our website](https://www.hacdc.org/visit/). Join the discord for questions / help getting in (use channel #let-me-in) [https://discord.gg/dNjuNhNmeT](https://discord.gg/dNjuNhNmeT)

Hello Euchre Enthusiasts – We are back at the [Irish Channel Restaurant & Pub](https://www.irishchanneldc.com/) in Chinatown on 6/1. **Please RSVP to indicate your attendance and HONOR YOUR RSVP**. If your plans change and you are unable to attend, please update your RSVP. Regular no-show or late notices may get you dropped from the group. It is important that we are able to provide an accurate count to the venue and that all people who want to AND are able to attend are able to do so. **We ask all attendees to pay $1 to participate in the meetup.** This money helps maintain our meetup membership & cover various meetup costs that arise. You can pay $1 on Venmo @amanda-uherek, via Pay-Pal, or in-person (please choose paying friend/family not a business, good or service). All attendees are encouraged to support the business. ***REMINDER:*** everyone is responsible for their own tabs. If you have questions / comments / suggestions please message us. We'll have hand sanitizer & decks of cards on hand, you bring the smack talk. Cheers - Amanda

**The rules are simple:** Take photographs **Each and Every Day,** and post your best **ONE** (1) shot of the day - **EACH DAY** for **May**. If you happen to miss a day or two (life happens), it is **OK** to catch up and upload the photos for the days missed or just skip those days. **Please don't post over 2 to 3 at a time**. This is part of the learning process. **DO NOT POST TO THE ALBUM *UNTIL* AFTER 06/01/2026**. Please use a browser like Chrome and the Meetup.com website to post the images, as **the Meetup app does not handle albums very well**. Towards the top-left of the page is a link to **Add Photos** for uploading your photo to the album. **CONFIRM** **that your photo was added to the correct Album.** Remember to post your **best photo (JUST ONE)** you took every day on that day! **DO NOT POST PHOTOS FROM ANY OTHER TIME!** If you have time to post an older image, you can take a new image and post it. Be creative. Please **add a caption** to know how far you are in the process. After you upload the image you took that day, find your photo at the end of the album, and edit the caption to state the day and total number of days in the month like this:**?/30**. You can add the title of the image if you wish. A good title can make a photo! So, your photo for the **June 1st** caption would be "**1/30: My great photo!**" \*\* Adding a caption helps you keep track of where you are in the month. It does help. The purpose is to have fun and get in the habit of shooting every day. Learn to use your camera. Read your manual and test out a new feature you have never used before. Sometimes picking a theme/project can help focus (pun intended), like flowers, your pet(s), a lens you haven't used in a while, or whatever your passion is. Or try something new... The **end date is 06/30/2026**. Meetup.com does not allow events to be longer than 2 weeks. Other images that were not taken by you will be removed. Please keep the images family-friendly. You need to be a member of the Virginia Beltway Photography Group. I look forward to seeing how far people go and grow as better photographers!

Nervous about reading for others? Or just want to learn how? Do you want an opportunity to practice in a supportive environment?

For those of you taking the Tarot 101 classes, this will also be a chance to put into practice what you learned there. ($5 discount on this class, if you take both, making a $10 total discount. Remember to register for both classes individually. You do not need to take Tarot 101 to participate in the practicum.)

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/")

These sessions will be moderated by Columbus Unity Reiki. Reiki is a hands-on energy healing method from Japan that first came to the United States in 1938. Since then, it has grown in popularity and is now widely practiced throughout the West. All levels are welcome, and you do not need to be a practitioner at Unity of Columbus to attend. If you are a Reiki practitioner, a Reiki student, or simply interested in becoming a Reiki student, we warmly invite you to join us. Come practice your healing techniques, learn new approaches, receive healing energy, and connect with a like-minded community in a space of relaxation, renewal, and positive energy.
