USD Physics Team Publishes First Quantum Science Paper in a Leading Journal
The publication presents a germanium-based qubit platform that uses engineered phononic structures to couple and control hole-spin qubits, a pathway designed for scalability and compatibility with cryogenic operation. The study details device-level modeling, coupling mechanisms and performance metrics that link materials choices to qubit behavior—laying groundwork for future prototyping and system integration.
“This paper marks a significant step for our group and for USD,” said Mei, principal investigator. “By uniting high-purity germanium expertise with next-generation quantum architectures, we’re opening practical routes to scalable quantum devices while building South Dakota’s capacity in a strategic technology area.”
The work represents a major milestone for Germanium-based Science and Technology Advancement Research, an initiative led by USD. Ge-STAR expands the university’s longstanding strengths in particle and nuclear physics into modern quantum science and technology, helping position South Dakota as an emerging contributor to the national quantum ecosystem.
