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.

What would it mean to take the possibility of machine consciousness seriously? To approach it as a question that may be studied with rigor? At this DC Digital Minds gathering, group organizer **Jessie Mannisto** will report back from the **Founding Assembly for Machine Consciousness Research** in Berkeley, CA, where researchers and thinkers are working to develop the machine consciousness hypothesis into something more scientifically useful. We’ll talk about what kinds of evidence might support hypotheses of machine conscience or sentience, what concepts researchers are using, where the major uncertainties are, and why these questions may have ethical, social, and policy implications as AI systems become more capable and socially present. This will be a casual conversation with a little structure: Jessie will give a short report-back from the conference, followed by open discussion. No technical background required -- just curiosity, good faith, and a willingness to think carefully about a strange and important frontier. Optional Pre-Read: [The Machine Consciousness Hypothesis](https://cimc.ai/cimcHypothesis.pdf)

Speaker: Michelle Kleinhans is an avid native-plant gardener and nature lover who has transformed her conventional yard into a haven for wildlife. She will share with us fascinating facts about backyard fauna, explain why native plants are key to animal wellbeing and biodiversity, and steps you can take to protect local wildlife, even if you don't have a yard of your own. Finally, she will discuss how native-plant gardening relates to veganism and how one can practice animal-rights activism within the gardening community. Join your fellow animal lovers and DC Animal Protection to discuss what’s happening in the animal advocacy scene in DC! This series is a weekly meetup, with guest speakers from all of the major animals rights orgs. We’ll host non-profits such as Pro-Animal Future, International Council for Animal Welfare, DC Voters for Animals, The Humane League, Mercy for Animals and Direct Action Everywhere as well as local grassroots groups like the DC Coalition Against Foie Gras and sanctuaries. We’ll also have special sessions related to health, nutrition and mindfulness! We encourage anyone who is interested in helping animals to attend- no need to be vegan! Come learn about our rich variety of local activism. With protests, outreach, wheat-pasting, signature collecting, leafletting, lobbying, tabling etc. there’s something to match everyone’s comfort level and skill set. Coffee, bagels and community will be provided! Feel free to bring any extra treats to share (no animal products please.) Hope to see you soon! :) Note: Unfortunately, animals are not allowed at our venue. Please leave your furry friends at home.

NFT's are here to stay folks! This is a group for like minded people interested in understanding, leveraging, using, creating for, profiting from, trading too i suppose, NFT's.. everything around them, complexity, fear and exploits, best practices and more. **PLUS** This group will talk AI ART tools, techniques, artists, video, audio, prototypes and more in the AI assisted production space- ART specifically, but we can get into any aspect of some of the cooler things happening in AI in general.

**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.
