“The challenge in the quantum industry is no longer a science challenge: it’s becoming an engineering challenge.”

Xuanjing Chu

How was the process to figure out your method?

I’m an experimentalist, but we had to go pretty heavily into theory and modeling for this paper. Usually, you think a theory is out there in the literature, even if it’s a few decades old, and that if there isn’t a supporting theory, you’ve done something wrong in your experiments. But there was no theory for our specific experimental case! I had to learn about microwave engineering, and we had to do all the modeling and simulations ourselves. That’s a unique challenge!

What brought you to quantum, and to Columbia originally?

I did my undergraduate degree at Fudan University in Shanghai. I was leaning towards more traditional solid-state physics, but it became really exciting to see quantum computing concepts emerge. I started seeing more and more papers pop up, and I wanted to help make the impossible possible: to go from pure laboratory demonstrations to industry-level, practical techniques. I’m a superfan of science fiction, and we’re seeing the transition from the classical to the quantum world in everyday life. I want to be part of it. 

I was aware of Jim’s SuperVan collaboration with Kin Chung Fong to explore novel qubits, and I also love New York City. I love to bike around the five boroughs and feel the architecture, the people, and the cultures change. It can feel like you are in different cities. I’ve loved being exposed to the complexity of New York, which gives me a nice break from the lab.

What does the quantum future hold?

The challenge in the quantum industry is no longer a science challenge: it’s becoming an engineering challenge. That will take a lot of people from different backgrounds to overcome. We live in a classical world, so quantum mechanics can feel intimidating, but don’t be afraid. Now is the time to jump in!

Many of the projects in this year’s expo integrated AI with custom hardware. The Clinical Handwashing Coach, which tracks handwashing sessions, is being tested at a hospital in Pasadena, California. The team of electrical engineering students designed an AI system to ensure that medical professionals comply with handwashing protocols. Other teams from the department used AI to create noise-canceling headphones with real-time language detection and translation (team ANURA) and a wearable device that inexpensively creates digital transcriptions (CLACS).

A couple of projects tackled wheelchair comfort and mobility autonomy. The Mechanical Engineering team STAR (Self-Transfer with Automated Reversing) Lift made moving in and out of a wheelchair easier for wheelchair users with upper-body mobility, allowing them to transfer themselves to a bed without assistance. Team Wheel-E created a specialized seat cushion for wheelchair users that helps alleviate the painful symptoms of prolonged sitting. 

Urban green infrastructure was the main theme for many projects in the Department of Civil Engineering and Engineering Mechanics. The Morningside Park Rehabilitation Project reimagined the local neighborhood park by proposing two new community centers for public use and an upgraded drainage system that can handle heavier rainfall runoff. 

From AI devices to reimagining a neighborhood park, the Class of 2026 proved that the best engineering goes beyond the classroom and makes an impact in the world.

Dean Shih-Fu Chang recognized Raymond P. Daddazio BS'75, MS'76, EngScD'82 with the Thomas Egleston Medal for Distinguished Engineering Achievement. Daddazio is chairman of the Thornton Tomasetti Foundation and former president of Thornton Tomasetti. Dean Chang also recognized Azmi T. Mikati BS'94, the CEO of M1 Group, with the Samuel Johnson Medal for Distinguished Achievement Beyond Engineering and Applied Science.

Over the weekend, alumni and guests attended lectures from Columbia Engineering faculty, including a talk on AI and neural intelligence with Richard Zemel, Trianthe Dakolias Professor of Engineering and Applied Science and professor of computer science; as well as a presentation on energy, transition, and mining with Dan Steingart, Stanley-Thompson Professor of Chemical Metallurgy, professor of chemical engineering, and chair of the Department of Earth and Environmental Engineering. 

On Friday, attendees toured the Plasma Physics Lab and the Robotics and Rehabilitation (RoAR) Lab. They also mingled at a general All Class Reception and recognized classes celebrating their 50- and 25-year anniversaries. Members of the Class of 1976 received Golden Lions pins, while the Class of 2001 members received Silver Lions pins to commemorate the milestone and their entry into the Golden and Silver Lions Societies. The day ended with a Reunion Lawn Party for alumni of Columbia Engineering, Columbia College, and the School of General Studies.
