**[Constellations ](https://www.harringtonmatchmaking.com/constellations-membership)Patio Social + community lore activity** in Arlington, Virginia.
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.

Machine Learning for Reliable Quantum Computing: An Algorithm–Hardware
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.

Let’s head to upper Northwest DC for an Indian dinner at Masala Art in Tenleytown, a long-running neighborhood favorite known for refined North Indian cuisine and regional specialties. The restaurant was founded by chef Surinder Singh, formerly of Heritage India, and continues to maintain a strong reputation for consistent execution and depth of flavor.
**FOOD**: Masala Art focuses on North Indian cuisine with a mix of classic curries, tandoori dishes, and harder-to-find regional specialties, vegetarian & GF friendly. Recent diners frequently highlight the Railway Lamb Curry, lamb korma dishes, garlic naan, and vegetarian items such as baingan bharta and okra preparations. Tandoori items and biryanis are also consistently well reviewed, with many diners noting balanced spice levels and strong flavor without excessive heaviness.
The menu supports a wide range of preferences, including vegetarian-friendly selections and several richer meat-based dishes. Expect traditional Indian desserts and a full bar with wine, cocktails, and beer available.
Most members should expect total spend to land roughly in the 40 to 70 dollar range, depending on ordering style & beverage participation.

**CLOSEST METRO**:
* **Tenleytown–AU station (Red)** is the closest stop. Quick walk (exit on Tenleytown EAST (same side as Whole Foods) walk south along Wisconsin Ave & cross over Albermarle St NW). The walk is a quick 3–5 minutes based on routed walking directions and traffic signals.
* For directions using the Metro, try using the Plan a Trip feature at the WMATA website ([click on your preferred Metro station](https://www.wmata.com/rider-guide/stations/index.cfm) then at the Station page level click "Plan a Trip".
**PARKING**: Street parking and several public parking garages are available throughout Tenleytown. Weekend evening parking is generally easier here than in central DC neighborhoods, though nearby retail activity can still affect availability. Members may also want to check parking apps such as SpotHero and Parking Panda for discounted garage reservations and advance booking options nearby. Plan accordingly.
***Attendance Notes:***
* **If you RSVP “YES,” please commit to showing up***. With 5,400+ members and limited seating, we can’t afford no-shows. It’s not fair to other members or to our relationship with the restaurant.*
* **New Members / 1st Timers: Trying to get a slot?** Join the Waitlist and check back frequently: spots (*often open up before Noon on the day of the event. You may also receive midweek confirmation emails to reconfirm your RSVP, so please check your Meetup DMs inbox).*\*\*
* **Billing Reminder - Add 30% for tax and tip to your food and drink total.** This is part of our group’s expectations and helps smooth out service with the restaurant.
Looking forward to dining with you!

In-Person Event: The Answers to Depression & Anxiety
This is an in-person meeting. At this meeting you will get answers to depression and anxiety. Find out the source of them and how to get rid of them.
Did you know that unwanted emotions like anxiety, depression, unhappiness, loneliness, hopelessness, anger, fear, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not due to a chemical imbalance in your brain from some nebulous chemical reaction "by chance".
Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you.
The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life.
Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life.
Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there.
This group is created by the Hubbard Dianetics Foundation of Central Ohio and Church of Scientology of Central Ohio.
