Nervous about reading for others? Or just want to learn how? Do you want an opportunity to practice in a supportive environment? Join Gypsy Dervish as he leads us through the basic practice of reading the Tarot. Ask questions , participate in group readings, and read for other participants. 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.)

**Location**: Tysons-Pimmit Regional Library (Virginia) Conference Room A game development **Working Session** involves 3 key parts: 1. Tell people what you're going to do 2. Actually do stuff 3. Show people what you did That's what we'll be doing for this meeting. We'll briefly tell each other what we're going to do, then work on our projects, then at around 5:30 wrap up to show each other what we did and chat for a bit. You don't have to stay the whole time, so feel free to drop in and out as you have time. All game development skill levels welcome. Whether you're bringing a game you're trying to ship in a month, or you're just planning on following some tutorials or trying out a new tool to improve your skills, use this time to make progress. Working sessions also train you to think about the scope of your work: pick a chunk of work that you can complete in the time that we have. That way you can end the working session with a feeling of accomplishment! **What to bring**: Laptop, Charger, maybe a power strip if you have one handy, any other game development tools you need. Try to download any software you need before the working session. There is Wifi at this location, but it may be slow if you have to download any large files.

DC Code and Coffee is an inclusive, informal co-working session. It's community-led and community-run by devs, for devs. People of all skill levels attend. Whether you’re dev-curious, aspiring, or a professional developer, we’d love to have you! Come chat or learn to code on a Sunday afternoon with coffee and cool-inclusive people. Bring your laptop! We typically meet every month on the weekend. **Join our online community!** For all things Tech in DC and to get latest updates and tech events from the DMV area, join the [DCTech Slack](https://dctech.chat/). All DC Code & Coffee announcements are in the #dccodecoffee channel **How it works** Near the beginning of the event, we do an introduction circle. You say your name, what you can help others with, and what you would like help with. You can also share job opportunities. After the introduction circle, everything is self-organized.

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.
