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.

It was first lit on May 3, 1856 by keeper George L. Deeton. Today it is the focal point of Jones Point Park and a clue to area's history as a busy commercial center and naval base. Whale oil lamps were originally used to power the beacon at Jones Point, but in 1858 the Lighthouse Board allowed an Alexandria gas company to extend lines to the station. The land included one of the original District of Columbia boundary stones, which was installed by George Washington and marked the southern point of the ten-mile-square district. The stone is still visible today in the seawall just south of the lighthouse, and to the north of the lighthouse a marker designating the boundary between Maryland-Virginia can be seen. **About Fort Foote** Fort Foote was constructed in 1863 atop Rozier's Bluff to strengthen the ring of fortifications that encircled Washington, D.C. Two of the Guns that protected Washington are still there along with the remains of the fort's earthworks. **About the Woodrow Wilson Memorial Bridge** Also known as the Woodrow Wilson Bridge or the Wilson Bridge, the bridge is a bascule bridge that spans the Potomac River between the city of Alexandria, Virginia, and Oxon Hill in Prince George's County, Maryland. The original bridge was one of only a handful of drawbridges in the U.S. Interstate Highway System. **About National Harbor** National Harbor is situated on the banks of the historic Potomac River, just minutes from the nation’s capital.

**History** The [Franklin Park Conservatory](https://www.fpconservatory.org/)’s roots trace back to 1852 when the Franklin County Agricultural Society purchased 88 acres of land to host the Ohio State Fair. After the fair moved to its permanent home, the city of Columbus transformed the grounds into Franklin Park in 1884. This transition shifted the space from a temporary event site to a dedicated public green space for the growing community. The park became a central hub for outdoor recreation and early civic gatherings in the neighborhood. In 1895, the landmark Victorian-style Palm House opened its doors, drawing heavy inspiration from the Glass Palace of the 1893 World’s Columbian Exposition in Chicago. This iron and glass structure became an immediate icon, housing exotic plants that residents would otherwise never see in the Midwest. It remains the oldest part of the facility and serves as a primary link to the conservatory’s 19th-century origins. For decades, it stood as a singular testament to grand horticultural architecture in Central Ohio. A major turning point arrived in 1992 when Columbus hosted AmeriFlora '92, an international horticultural exhibition. This massive event prompted a $16 million renovation and expansion, adding significantly more greenhouse space and the Dorothy M. Davis Showhouse. The festival put the conservatory on the international map and fundamentally changed its scale and ambition. Following the event, the facility transitioned from a city-run park to a private, non-profit organization. In 2003, the conservatory’s identity was further defined through a long-term partnership with world-renowned glass artist Dale Chihuly. After a successful exhibition, the Friends of the Conservatory purchased most of the glass installations, creating the largest permanent collection of Chihuly’s work in a botanical setting. These vibrant glass sculptures are now woven throughout the biomes, blending art with nature. This addition helped cement the conservatory as a premier cultural destination rather than just a botanical garden. Recent years have seen the site expand beyond the glass walls to emphasize community engagement and outdoor education. The 2018 opening of the Scotts Miracle-Gro Foundation Children’s Garden added two acres of interactive landscape designed for hands-on learning. The Scotts Miracle-Gro Company Community Garden Campus also provides local residents with space to grow their own food and learn sustainable practices. Today, the conservatory balances its historic Victorian charm with modern commitments to local ecology and the Columbus community. **Maps of the Conservatory** Here is the [main map](https://www.fpconservatory.org/wp-content/uploads/2025/08/franklin-park-zones-scaled.jpg) of the Conservatory grounds. Here's a [map of the areas](https://www.fpconservatory.org/wp-content/uploads/2026/02/ConstructionMap-2026.jpg) in which the Conservatory has ongoing construction (see below). **Summary** For this event, we'll explore Columbus's highly-rated and very popular Conservatory. As mentioned above, the Conservatory is doing renovations on parts of the facility. These renovations are scheduled to be ongoing until the Fall of next year. Basically, no matter when you go to the Conservatory over the next 18 months, you're going to see some metaphorical orange barrels. So let's just go now. **Tickets and pricing** On the first Sunday of every month, the Conservatory is free for residents of Franklin County and the city of Columbus. You must bring an ID to receive this discount. (Yes, they do check.) Otherwise, tickets are $25.20. Members of the Columbus Zoo (of which I am one) do get a discount on tickets, though I have never actually bought a ticket to the Conservatory (I've always gone on free days). I believe the discount is $4. Parking is always free. If you have additional questions about pricing or whether and for what you qualify, you can reach the Conservatory at 614-715-8000. **Where we'll meet** We will meet just outside the main entrance. I guarantee there's going to be a line. The Conservatory is always popular on free days, and especially in nice weather. **Your GPS is stupid!** Be careful simply typing "Franklin Park Conservatory" in your GPS and going where it tells you. The only way to access the parking lot to the Conservatory is off of Broad Street. Unfortunately, since Google Maps is unable to find its way out of a wet paper bag, it has a tendency to want to take people to a mythical, non-existent Conservatory entrance on Nelson Road. If your GPS does this, just drive to the north side of the Conservatory along Broad Street. Your GPS should then redirect you to the main Conservatory entrance. If your GPS doesn't, then throw your phone away\* and look for the big Conservatory sign on the south side of Broad Street between Nelson Road and Franklin Park West. You also should be able to use the map pin I've provided, below, and it should properly direct you to where you need to drive. \* Don't really do this. **After the event** After stopping to smell the roses, for those that are interested, we'll head to the nearby [Columbus Brewing Company Beer Hall](https://columbusbrewing.com/location/beer-hall/) for [drinks](https://columbusbrewing.com/location/beer-hall/#draft-list) and [lunch](https://columbusbrewing.com/location/beer-hall/#food-menu). The Beer Hall's actual address is [200 Kelton Ave, Columbus, OH 43205](https://www.google.com/maps/place/200+Kelton+Ave,+Columbus,+OH+43205/data=!4m2!3m1!1s0x883889a94ac4acad:0xadb2e60240dbc38b?sa=X&ved=1t:242&ictx=111) (it's literally just on the south side of the Conservatory). Be sure this is where your GPS is taking you when you use it, as the Brewing Company has a taproom on Harrison Avenue that is *not* what you want for this event. We should be at the Beer Hall by 1 if you can't make the Conservatory and just want to join us for drinks.

5:45-7:45 in Conference Room A, Library lower level. Bring your yarn projects, meet new friends. If you plan to attend, please RSVP yes. If you can’t attend, please change your RSVP to no. This helps anyone who is waitlisted and it allows me to have an accurate count of attendees as our space is quite limited. Plenty of parking in the lot, in the overflow lot across the street, and on the street. See you there!

Let’s meet and wander the galleries! General admission on Sundays is free.
