New Materials Systems for Quantum Defects

Abstract

Our work has focused on a systematic search aimed at the discovery of new solid state materials with defects that will act as bits for storing and processing quantum information. Although much progress has been made towards control of individual quantum defects in the solid state for applications in quantum information science and technology, prior work in this field has relied on the serendipitous, not the systematic, discovery of new materials and defects. In the first phase of this project, we leveraged our collaborative strengths in materials growth, defect engineering, spectroscopy, and confocal microscopy to create a screening pipeline for new quantum defects using complementary optical and spin spectroscopy techniques, combined with materials processing capabilities. This pipeline has allowed us to explore several new color centers in diamond, over a dozen new host materials for Er3+, and bulk and surface doping methods to stabilize particular charge states of quantum defects. This rate of exploration is orders of magnitude faster than the previous norm in the community, allowing us to uncover materials principles for new quantum defects, and filling out the periodic table of atomic defects relevant to quantum information science and technology. This work will enable emerging technologies in quantum information processing, nanoscale sensing, quantum metrology, and quantum communication.
