Quantum science and technology rests on our understanding and control of matter and light at the smallest scales. Devices based on precise arrangements of individual atoms represent the ultimate limit in a process of miniaturization that has defined the semiconductor era. Ironically, the same atom-scale defects that are often the bane of today's semiconductor devices exhibit quantum-mechanical features comparable to isolated atoms or molecules, and they can be the key to realizing compact, efficient quantum technologies. I will describe recent progress in identifying, creating, and controlling quantum states using defects in solid-state devices. I will discuss our group's work to design new photonic device architectures and quantum control protocols that boost the performance of quantum memory nodes and nanoscale quantum sensors based on nitrogen-vacancy centers in diamond, and parallel efforts to identify spin-qubit systems in new materials - especially two-dimensional hexagonal boron nitride - that expand the potential for exploring fundamental physical phenomena and designing novel quantum devices.
