Researchers have uncovered subtle optical signatures that could help distinguish atomic defects in a promising quantum material. An atomic defect too small to see could leave a recognizable signature in laser light, giving scientists a new way to identify structures that may be useful for quantum technology. Researchers at the University at Buffalo have predicted
