**This talk has completely sold out in advance and no additional tickets will be available at the door.** [Profs and Pints DC](https://www.profsandpints.com/washingtondc) presents: **“Inside the World Cup,”** a scholarly look at preparation for the upcoming soccer tournament and at the likely impact of major global sports events soon to be staged in the United States, with Matt Winkler, founder of American University’s online master’s program in sports analytics and management and former sports executive. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/dc-world-cup](https://events.ticketleap.com/tickets/profsandpints/dc-world-cup) .] The FIFA World Cup 2026 will soon take place in several cities throughout the U.S., Canada and Mexico. Come to Profs and Pints to get an industry insider’s perspective on it and other global sports events being hosted by American cities, including the 2028 Summer Olympics in Los Angeles and the 2034 Winter Olympics in Salt Lake City. Learn about the preparation for these events, about their projected economic and cultural impact, and about remaining uncertainties surrounding them with Matt Winkler, a scholar and teacher of sports management and business with years of experience working with the World Cup, the Olympics, and various professional sports leagues. He’ll discuss issues related to the FIFA World Cup’s governance, site preparation, security, fan management, and tourist visas, and he’ll weigh how the $13 billion dollars in revenue projected to be generated by the tournament compares to the costs of staging 104 games between 48 countries. He’ll delve into how the tournament symbolizes a pivotal moment in the evolution of soccer in America, with global games broadcast all over American television channels and streaming services. You’ll learn how the 1994 World Cup in the United States significantly boosted soccer’s popularity—leading to increased youth participation and the establishment of Major League Soccer—and how the sport has continued to rapidly gain traction here in recent years. We’ll consider how the World Cup marks the beginning of an unprecedented run of major global sports events in the U.S., including not just summer and winter Olympics but, in 2031, the U.S.-hosted FIFA Women’s World Cup and 2033 men’s and women’s rugby World Cups. Among the questions Winkler will tackle: How will the U.S.-Israel attacks on Iran affect the World Cup? How will tickets sell, and at what price? (Doors: $17, or $15 with a student ID. Listed time is for doors. The talk starts 30 minutes later.) Image: Soccer being played in New Jersey’s MetLife Stadium, one of the venues hosting the 2026 FIFA World Cup.

These rides were originally based off the Arlington Loop where we visit different area coffee shops or bakeries for a cup and/or treat if desired but you don't have to drink or even like coffee to participate. This week we will return to Vienna to celebrate **Innergize Day** because Fall has fell and we want to do something for ourselves. The ride is a 18.7 mile medium(-) level ridden at a social pace (11-13 mph). We will get on the W&OD from the Bluemont Park Parking Lot and take the W&OD, I-66 Parallel Trail and some neighborhood streets to Vienna for coffee at the Frame Coffee Roasters. Afterwards we will zip back downhill on the W&OD to the starting point. **+++++++++++++++++++++** **The Ride After The Ride:** **+++++++++++++++++++++** This week's coffee shop is the Ride WITHIN The Ride at: **[FRAME COFFEE ROASTERS](https://www.framecoffee.net/)** 302 Maple Ave W Vienna, VA This is a small venue with limited seating **+++++++++++++++++++++** **Ride Level Chart** **+++++++++++++++++++++** NoVA CBG tries to accommodate all levels of cyclists by offering different types/levels of rides.

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.

**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.
