**THE POWER OF THE SUBCONSCIOUS OVER YOU** You are welcome to arrive 15 minutes early for refreshments! At the lecture "The Power of the Subconscious", the speaker will clearly and understandably explain topics such as: * What is the exact definition of the Subconscious Mind? * How does it inflict unwanted feelings and anxiety in you? * What determines how much pressure it exerts on a person? * What exactly is the goal of the subconscious? This is not just a lecture where you sit quietly and listen. It's interactive and LIVE, so you can ask questions at any time. And the most important topic: **HOW DO YOU TAKE CONTROL OF YOUR SUBCOUNSCIOUS!** This group is sponsored by the Dianetics Life Improvement Center.

Let's kick off our Friday night with a fun stroll through one of DC’s best local events and neighborhood — the **[Dupont Circle ArtWalk](https://dupontcirclebid.org/events/artwalk-dupont)**! On the first Friday of each month from 6:00–8:00 p.m., art galleries, embassies, and cultural centers around Dupont Circle open their doors for a free, self-guided gallery walk. **5:30 PM:** Let’s meet up at the bar at **[Kramers](https://www.kramers.com/menu/happy-hour)** (1521 Connecticut Avenue NW - two doors up from the bookstore entrance) while everyone arrives. **6:00 PM:** We’ll head out to soak in some art, explore the neighborhood, and enjoy the evening together. Here's a suggested itinerary: * Church of Scientology - National Affairs Office (It's not scary - they don't try to recruit you or anything. They showcase the work of several contemporary artists, and it's in a historic mansion.) * **[Vika Gallery](https://vikagallery.org/)** * **[Washington Center of ADA Art Gallery](https://adawdc.org/en/view/23/28/spring_2026_exhibition)** * **[Alex Gallery](https://www.alexgalleries.com/alex-gallery)** * **[Studio Gallery](https://www.studiogallerydc.com/)** * **[IA&A at Hillyer](https://athillyer.org/exhibition-statuses/upcoming/)** **7:30 PM:** We can grab dinner from a local fast casual place. I'm partial to **[Tiki Taco](https://www.tikitacodc.com/)**, but please feel free to share suggestions in the comments! The closest Metro station is Dupont Circle (take the north entrance). The closest bus stops are the D74 and D96 at Connecticut Avenue and Q Street NW. There are a few parking garages around the circle.

This will be a relaxed patio social for neurodivergent adults (most will be 20s/30s) focused on conversation and meeting new people through a low-key activity. Participate in our “Community Lore” activity — a social scavenger hunt-style game designed to make mingling feel easier and spark better conversation. Before the event, attendees will submit a few fun facts, unusual skills, niche interests, and/or random details about themselves. We use these anonymous submissions to create the activity cards. When guests arrive, anyone who wants to participate will receive a card featuring fun facts submitted by other attendees. As you mingle throughout the evening, you’ll try to figure out which person matches each item on your card. We’ll have reserved patio seating, casual games, complimentary appetizers, and drinks available for the group. Alcoholic beverages and additional food or entrees can be purchased individually. While we do have reserved patio seating, this may not be the best fit for individuals who are highly sensitive to noise or busy environments. **Click [here](https://www.eventbrite.com/e/patio-social-for-neurodivergent-adults-tickets-1990579924138 ) for non-members to register and submit your info for the activity.**

The Mission: Finding Your Strength It’s natural to feel intimidated by the idea of a self-defense class. At Kore, our “First Friday” sessions are designed to replace that hesitation with confidence. This isn’t about traditional “gym moves” or martial arts rituals—it’s about taking agency over your life. Taught by our Certified Female Instructors, this free workshop focuses on practical applications of the Kore Standard. We help you sharpen your natural intuition and provide a toolkit of effective, simple responses to common safety concerns. This is about building the confidence to navigate the world on your own terms.

With war breaking out, the gnomes of Brastlewark in Cheliax can no longer cling to their carefree ways. Self-proclaimed King Drum Thornfiddle is eager to ingratiate himself to Queen Abrogail, and so conscripts the city's magical and creative resources towards the war effort. A few gnomes have broken free, and they have brought evidence of the various works being created in Brastlewark. They're no fighters, though. It'll be up to the Pathfinders to get them safely across the border to Andoran and freedom. A Pathfinder Society Scenario designed for 1st- through 4th-level characters, playable in 4-5 hours.

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/")
