Welcome to the de Leon Group
The de Leon lab is focused on building quantum devices with color centers in wide bandgap materials. These color centers act as artificial atoms in the solid state, and can have remarkable optical and spin properties. We study nanophotonics, device physics, quantum optics, spectroscopy, and materials science in diamond with the technological goals of realizing quantum networks and nanoscale sensors. We are also interested in exploring fundamental quantum optics, magnetism and interactions between spins, and new material systems for quantum technologies. Our group is highly interdisciplinary, and our work spans optics and photonics, surface science and materials spectroscopy, atomic physics techniques, nanofabrication, optoelectronics, and cryogenics. We are fortunate to have collaborators around the world that are experts in diamond synthesis, processing, and characterization, surface spectroscopy, EPR, STM, and DFT calculations of defects in wide bandgap materials.
We collaborate broadly, and benefit from a large research community focused on quantum science and engineering at Princeton:
