Argonne links quantum sensing to high-energy physics research

A $1 million, three-year project at Argonne National Laboratory is linking quantum sensing with high-energy physics research, aiming to map electromagnetic fields with greater accuracy. The effort centers on nitrogen-vacancy qubits within diamond membranes, tiny defects that shift energy states in response to magnetic and electric fields. “Five or 10 years ago, this was kind of science fiction,” said Argonne scientist Nazar Delegan, “But now we think that these are practical paths to making the devices useful for other scientists and ourselves.” Researchers plan to build prototypes adaptable to future particle accelerators, addressing a common need for precise magnetic field mapping. Nitrogen-Vacancy Centers Enable High-Precision Electromagnetic Field Mapping Diamond-based quantum sensors developed at Argonne National Laboratory are expected to improve the precision of electromagnetic field mapping within high-energy physics experiments, a capability crucial for understanding fundamental particle interactions. The recently launched, $1 million three-year project aims to integrate these sensors directly into existing and future particle accelerator systems, addressing a long-standing need for more accurate field measurements. Argonne physicist Peter Winter explained the core challenge: “One commonality across many of these experiments is that they have magnetic fields that they need for various purposes. And they often have strict requirements for mapping this magnetic field with high precision.” The sensors utilize nitrogen-vacancy centers, or NV centers, which are atomic-scale defects within diamond crystals. These NV centers function as miniature magnets whose energy states are acutely sensitive to surrounding electromagnetic fields, allowing for extraordinarily precise readings when stimulated with light and microwaves. Researchers are now adapting this established technology to the specific demands of particle physics, focusing on creating sensors that can withstand harsh experimental conditions and seamlessly integrate with existing microelectronics. “What’s ideal here is that we’ve developed a technologically integratable platform where we can put in these quantum sensors into existing microelectronic systems,” said Argonne scientist Nazar Delegan, project co-lead. This adaptability is key, as different high-energy physics experiments present unique challenges; some require operation in high-radiation environments, while others demand exceptionally precise measurements within limited spaces. The project will focus on building prototype sensors and large-area mapping systems, as well as developing sensor arrays capable of functioning in rapidly changing electromagnetic fields. Beyond the technical advancements, the project is designed to foster interdisciplinary collaboration and train the next generation of scientists. “One of the things I’m excited about is bringing on board a junior scientist who will adopt both fields and start to act almost like an ambassador for the two, and seeing that development is obviously rewarding,” Delegan added, highlighting the project’s commitment to workforce development. Ultimately, the team envisions a versatile platform for electromagnetic field mapping applicable to a wide range of experiments, with the potential for broader commercial applications. What’s ideal here is that we’ve developed this technologically integratable platform where for the first time we can actually put in these quantum sensors into existing microelectronic systems.
