We will have open shop hours for anyone to bring their bikes to work on or need help fixing your own bike. We will also have bikes that need to be fixed so you can learn if you like. We will need everyone to sign in when arriving and sign out when leaving so we can keep track of volunteer hours and shop times. Suggested donation of $15 per hour for use of tools and space would be appreciated. Thank you!

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/")

Next up is Open City, the cafe of the National Cathedral. You can enjoy a drink and snack while you sit at the tables, or wander around the cathedral to find a subject. https://www.opencitycathedraldc.com/

Join local video game developers, artists, musicians and writers to talk about the art and science of game development. Bring a device and demo your game, talk shop, find like minded folks to join forces with, have a snack or a beverage among new friends. We are an informal meetup where we share what we've been working on and socialize. Come for all or just a bit of the time!

We’ll sample the espresso at this Fairfax cafe next. There are some unique offerings on the menu, so let’s get together and compare notes. Enjoy your favorite drink or try something new. I love to start my weekends off this way. Come join us. (Please keep your RSVP updated if you know you won't be able to attend, so others who can join have the opportunity to. No discussions on politics, religion or potentially controversial topics. We're here to relax and have fun. Just be respectful and we'll be alright. Pay your own way, and enjoy!)

Socrates Café meets twice a month. Though this may be considered a "philosophical" group, there are no rules as to what is discussed. Usually, the topics revolve around social concerns, morality, and the first principles of things. Prior to each meeting we vote online for the questions we will discuss. That way, we will have enough time to ruminate on them and have more in-depth conversations. If you RSVP to a meeting, you may post your question in the event comments section below. I'll send out a survey for voting a few days prior to the meetup. We discuss two questions each night. So you will get to cast two votes in the survey. When we meet, we break into smaller groups of five to seven to discuss the top two vote-getters. Each group discusses one question for around 45-50 minutes, and we then take a short break. After reconvening, each group moves on to its second question. Hope to see you there! -Brian
