After hosting successful events, I always think that we could have done better and relate it to our day to day life and make it educational. In this connection, I wanted to show off my investment and trade hat and organize series of Happy Hours around Investment & Trade. We will have speakers from different sectors and industries, at each Happy Hour. At this particular event, the speaker will discusses Smart Strategies for Maximizing Social Security . Topics will include: 1. Today’s retirement challenges 2. Keys to help you understand the basics of Social Security, including when you should start taking benefits 3. Qualifications for retirement benefits and survivor benefits 4. Sources of income in retirement 5. Building an income plan. The address will be sent to members, who RSVPed, before the Event. Enjoy!

Today we are Steve's Lab. RSVP and you'll be sent the location. It's in Silver Spring. ***Join us for an evening in an electronics lab where we will attempt to run clean scans of graphene and gold samples, and then clean up that data with post processing.*** This is a high sensitivity experiment, and we do not plan on being successful so early. But we've had promising results lately - so we will be putting in the time. We are NOT meeting at our usual location, but rather at Steve's house/lab. If you RSVP, you will get a DM with the address but it's located in Silver Spring. We will attempt full, clean lab - clean tip repeated scanning tests to see what we can learn and improve. We will experiment with online attendees, but if all possible showing up in person is strongly encouraged. Online join link is: - [https://meet.jit.si/mocomakers](https://meet.jit.si/mocomakers) Our community is building (and documenting for other teams) how to build a scanning tunneling microscope using a mix of common and 3D printed parts. This will allow us to scan and visualize a single atom - an ambitious we are doing over the course of a few months. The MoCo Makers community is one of the most innovative and competent groups in Maryland, and we've done everything from [publishing cancer research](https://pubmed.ncbi.nlm.nih.gov/38136356/), to [launching products](https://www.kickstarter.com/projects/gotim/cozy-curvy-multi-contour-pillow), [winning grants](https://covidinfocommons.datascience.columbia.edu/awards/2014255), and inspiring thousands. Now our biggest challenge yet has appeared. We are building a Scanning Tunneling Microscope, that will allow us to scan and visualize single atoms. To get a better idea of what we are doing, see our reference project here: [https://www.youtube.com/watch?v=7N3OqTEq08g](https://www.youtube.com/watch?v=7N3OqTEq08g) All starting CAD, code, and reference files should exist. However, let's be the first Maker community to document the build process and share it with learners around the world. We will be publishing our work here -[ https://hackaday.io/project/202816-qt-panda](https://hackaday.io/project/202816-qt-panda) If you need a ride, let us know.

This is a low-key happy hour bringing together designers and creatives across disciplines in the DMV to kickback, connect, and share ideas—no panels, no pitches, no pressure. We hope to see you there! **Music by: Friends on Mars** Hosted by Good People DC and **[SPD](https://www.spd.org/)**, a nonprofit design community rooted in publishing and creative excellence. No cover charge = no excuse not to come Must be 21 to enter. Please drink responsibly.

Come volunteer with us refurbishing donated bicycles so that they can be used again by the community! This event is open to new volunteers and existing volunteers. No mechanical experience is necessary. Note: The warehouse location is in the alley behind 1502 Mt Vernon Ave. Enter through the gray door next to a roll-down garage door. If you drive to the location, be sure to park in the street, not in the alleys or parking lots surrounding the warehouse. And wear clothes you don't mind getting dirty with bicycle grease! Volunteers under 18 need a parent or guardian to accompany them to their first volunteer experience and sign a liability waiver. Volunteers under 16 need a parent or guardian to accompany them at all times while volunteering with Vélocity.

Zorba's Cafe on Thursdays! We will be on the 2nd floor, or if the weather allows, we will be sitting outside at a table in the street. If you don't see anyone on the 2nd floor and the weather is favorable, it means we're sitting at the table in the street. Уважаемые участники группы! Информация для тех, кто еще не посещал наши встречи - обычно подписывается меньше людей, чем приходит на встречу, "старожилы" привыкли к тому, что записываться необязательно, и просто приходят в любое удобное для них время с 5:30 до 8 часов. Так что не стесняйтесь, записывайтесь на встречу! Welcome to the old venue! Old - since we used to get together at Zorba's Cafe for many years. Come to the 2nd floor. 1612 20th St NW, Washington, DC 20009 This is very close to Metro Dupont Circle station. This is the same place where we got together every Thursday evening for many years before 2015. Everyone is welcome, but please keep conversation in Russian only. For many of us, this is our only chance to practice our Russian. There are happy hour prices available. Timing: Someone is usually there by 5:30, but it sometimes takes the organizers till 5:45 or so. If you get there first, please wait - we will be there! And people are usually there till at least 8. So if you can't make it right at the beginning, that is perfectly fine to arrive late! RSVP's: I encourage you to RSVP. But please know that many people don't RSVP. So it may seem like only 3 people are planning to attend, but have no fear, we usually have a good-sized fun group! (And we almost always have newcomers. So if you are planning on coming for the first time, you most likely won't be the only one.) Also, when the weather is nice we are frequently sitting outdoors. So if nobody is on the second floor, just look for the group speaking Russian at tables out on the street. And to say again - we have often had only 3 or 4 people RSVP but have 15 or so show up. So don't worry about that. See you there! Questions? Check our FAQ (http://www.meetup.com/russki-razgovor-dc/pages/Frequently_Asked_Questions/) page.

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/")

**Talk Description** If you've ever wondered why pip install numpy and conda install numpy aren't the same thing, you've bumped into one of Python packaging's oldest fault lines. Conda and PyPI evolved to solve different problems, one for compiled scientific libraries, one for pure-Python code, and the gap between them has caused headaches ever since. We'll look at why the split happened, what's fundamentally different under the hood, and how the two ecosystems are starting to come together. **Agenda:** 7:00pm - Opening announcements 7:10pm - Bridging conda and PyPI ecosystems 7:50pm - Q&A
