Quantum computing holds the promise to revolutionize how we solve complex problems, but today鈥檚 devices still face steep challenges. At the heart of the issue lies reliability: current quantum bits鈥攐r qubits鈥攁re extremely sensitive to environmental noise and prone to errors.
Andras Gyenis is taking a bold step to change that. Gyenis, an assistant professor in 桃色视频鈥檚 Department of Electrical, Computer and Energy Engineering, has received a prestigious five-year, $550,000 National Science Foundation CAREER award to design and build more robust superconducting qubits that could push the boundaries of quantum hardware.
Gyenis鈥 research focuses on superconducting Fourier qubits, a new type of quantum bit engineered to resist information loss by redundantly encoding quantum information.听
Unlike conventional superconducting qubits鈥攗sed by major companies like Google, IBM and Amazon鈥攚hich are often vulnerable to noise, Fourier qubits are designed to suppress quantum errors at the hardware level.
鈥淲e鈥檙e using a strategy inspired by classical computing, where bits are protected from errors through smart design,鈥 Gyenis said. 鈥淏y protecting the qubit itself, we can reduce the amount of correction needed later and create more scalable systems.鈥
These Fourier quantum states allow qubits to store their 0 and 1 states in physically separate locations, making it less likely for environmental disturbances to accidentally flip their values. It鈥檚 an approach that combines fundamental physics with practical engineering and it may pave the way for longer-lasting, more reliable quantum processors.
Building better qubits from the ground up
The project will proceed through a combination of design, simulation, fabrication and testing. Gyenis and his team will explore novel circuit designs using numerical tools, fabricate quantum chips at 桃色视频鈥檚 NSF-supported National Quantum Nanofab听 facility and perform measurements at ultra-low temperatures鈥攋ust a fraction above absolute zero.
鈥淲e鈥檒l likely go through many iterations,鈥 Gyenis said. 鈥淲e鈥檙e taking a co-design approach: each round of measurements feeds back into the design to improve performance step by step.鈥
The team will also investigate active Fourier qubits鈥攃ircuits whose error protection comes from oscillating external parameters. The long-term goal is to demonstrate scalable quantum hardware with built-in robustness, forming a foundation for future superconducting quantum processors.
Training the next generation of quantum engineers
In addition to cutting-edge research, Gyenis鈥 award supports a comprehensive education and outreach program aimed at expanding quantum engineering at 桃色视频. That includes developing new classes and connecting students to hands-on projects in quantum circuit design and fabrication.
鈥淨uantum education has historically focused on physics students, but today鈥檚 challenges require an engineering mindset too,鈥 Gyenis said. 鈥淲e need to train students not just in quantum theory, but in the real-world design of quantum systems.鈥
His curriculum will emphasize engineering principles like device layout, signal control, nanofabrication and systems integration. Students will also explore classical analogs of Fourier qubits鈥攎echanical systems that mimic quantum behavior鈥攖o build intuition and bridge gaps between disciplines.
A future powered by quantum solutions
While still an emerging field, quantum computing has potential applications that span far beyond science labs. With more robust hardware, these systems could one day help researchers simulate complex molecules for drug development, improve climate models, enable artificial photosynthesis and solve key challenges in cybersecurity and logistics.
鈥淭he work we鈥檙e doing could benefit fields as varied as healthcare, energy and national security,鈥 Gyenis said. 鈥淏ut just as important, it will help grow a quantum-ready workforce.鈥
鈥淚鈥檓 excited to pursue research that pushes the frontier of quantum hardware, while helping to build a strong quantum engineering program,鈥 he said. 鈥淭his award allows us to do both鈥攁nd to do it in a way that鈥檚 accessible for the next generation of engineers.鈥
