Developing the Next Generation of Quantum Emitters in 2D Materials

The rapidly growing field of quantum information science promises revolutionary technologies such as provably secure quantum communication, high-precision quantum sensors, and optical microscopes capable of operation far below the diffraction limit. Despite considerable progress over the past three decades, large obstacles remain that prevent the application and commercialization of these technologies. In particular, there is an urgent need for reliable quantum solid-state optoelectronic devices.

This project takes a new approach to the generation and study of optical quantum emitters based on defects in solid-state materials. It combines state-of-the-art materials growth with a novel hybrid optical fluorescence/scanning tunneling microscope (STM) to directly link quantum emission properties to the atomic structure of the defects. The investigators will develop these techniques in 2D materials that represent a promising pathway for precision control of defects in a solid state platform, and have significant potential for scaling up to commercial devices and applications.
