Thomas Verrill, an electrical and computer engineering major at Princeton University, has taken significant strides in the field of quantum computing through his senior thesis. Despite initial nervousness when working in the university’s Micro/Nano Fabrication Center, Verrill quickly adapted to the precise environment required for fabricating advanced quantum chips.
Under the guidance of adviser Andrew Houck and with mentorship from graduate student Matthew Bland, Verrill designed new superconducting quantum computing chips. These chips use specialized materials to manipulate electrons with high precision, which is crucial for storing and processing information beyond the capabilities of classical computers.
Quantum computing faces challenges such as maintaining qubits in a stable state long enough for calculations. Houck suggested that using lower microwave frequencies might extend coherence times, but this requires larger chip designs that present unique challenges. “You have to be very strategic about where you put them,” said Verrill regarding the careful placement of qubits on these larger chips.
In a clean room setting at Princeton, Verrill used simulation software to refine chip designs before physical fabrication. His work represents a high-risk but well-defined approach within quantum research. Houck expressed enthusiasm for involving undergraduates in such pioneering projects: “These sort of high-risk but well-defined ideas are the kinds of ideas that I love to give to undergraduates.”
Beyond his technical pursuits, Verrill also engages deeply with music. He has been part of Princeton’s jazz band and hosts a radio show called “The Laboratory” on WPRB. His interest in creativity extends into both his musical endeavors and his approach to solving engineering problems: “I like the intersection of creativity and physically solving problems,” he noted.
Verrill’s passion for quantum research is evident not only in his academic work but also through his involvement with Princeton Students in Quantum, where he served as co-president and organized various events including workshops and industry trips.
After an internship with Rigetti Computing, Verrill plans to continue at Princeton as a master’s student while preparing for future roles in quantum computing industry research. He remains captivated by fundamental aspects like superposition and entanglement: “It’s this fundamentally new approach to information where you have all these new tools to work with,” he said.
