A powerful combination of high-throughput computation and precise fabrication techniques has been developed to accelerate the discovery of quantum defects.
• For the first time, researchers have demonstrated an approach that combines high-throughput computation and atomic-scale fabrication to engineer high-performance quantum defects.
• The methods provide a novel pathway to accelerate the discovery of quantum materials for game-changing applications in computing, telecommunications, and sensors.
• The study team identified and precisely fabricated a promising quantum defect that replaces a sulfur atom with cobalt in tungsten disulfide.
Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and several collaborating institutions have successfully demonstrated an innovative approach to finding breakthrough materials for quantum applications. The approach uses rapid computing methods to predict the properties of hundreds of materials, identifying short lists of the most promising ones. Then, precise fabrication methods are used to make the short-list materials and further evaluate their properties.
The study team included researchers at Dartmouth College, Penn State, Université Catholique de Louvain (UCLouvain), and the University of California, Merced.
“Together, these methods open the door for researchers to accelerate the discovery of quantum materials with specific functionalities that can revolutionize computing, telecommunications, and sensors.”
