COLLEGE PARK, Md. – The Quantum Technology Center (QTC) at the University of Maryland is receiving $1.5 million from the U.S. Department of Energy (DOE) for a project titled “High-Field Quantum Diamond Magnetometers” that is a collaboration with Commonwealth Fusion Systems (CFS), a Massachusetts Institute of Technology (MIT) spin-out commercializing fusion energy.
The award is part of $11 million in DOE funding for ten projects to be conducted over three years focusing on quantum information science that has applications to fusion and plasma science. Fusion energy is what powers the sun and stars and has long been viewed as the holy grail of energy research because of its potential to provide a clean, safe, and abundant source of energy on earth. Through joint research in fusion energy and quantum information science, these 10 DOE awards are intended to accelerate progress in fusion energy research through advances in quantum information science (QIS) and to advance QIS through groundbreaking techniques enabled by plasma science.
“I’m pleased that the University of Maryland will be receiving new funding from the Department of Energy for projects in fusion energy sciences,” said U.S. House Majority Leader Steny H. Hoyer, whose district includes the University of Maryland. “With this funding, the University of Maryland will help lead critical research on fusion energy, which is vital in our work to combat the climate crisis and move our nation toward cleaner sources of energy,” said Hoyer in the DOE announcement.
QIS research explores forms of computing and information processing to bypass “classical” physical limitations by relying on quantum effects. Through joint research in fusion energy and quantum information science, these awards have potential to accelerate progress in fusion energy research through advances in QIS, and to advance QIS through innovative techniques enabled by plasma science.
Led by UMD’s Ronald Walsworth, the founding director of the Quantum Technology Center (QTC) and by QTC Scientist Matthew Turner, the project utilizes advancements in quantum sensing with Nitrogen Vacancy (NV) centers in diamond to enable diagnostic capabilities in extreme environments necessary for practical commercial fusion device operation and other applications using high magnetic fields.
The goal of the project is to develop robust magnetometers, based on quantum defects in diamond, that can operate in the intense environment inside a tokamak fusion device. Arrays of high-field (between 1 and 20 Tesla) magnetometers are necessary for control and performance optimization of fusion plasmas. No existing magnetometers are known to meet the requirements of the extreme radiation, magnetic field, and temperature environment in a tokamak fusion device. Diamond is known to be robust to extreme radiation in other applications and theoretical estimates indicate that the diamond approach will be sensitive enough for the intended fusion applications.
“The DOE grant will enable experimental validation of the high-field quantum diamond magnetometers and demonstration of robustness in extreme environments,” said Walsworth, who is also a Minta Martin Professor of Electrical and Computer Engineering and Physics.
The QTC project was selected by competitive peer review under the DOE Funding Opportunity Announcement for Quantum Information Science Research for Fusion Energy Sciences and a companion National Laboratory Announcement. View the complete list of projects here.
