Smith Research Group

Brian J. Smith is an academic expert in quantum optics, quantum information science and technology, optical physics, and nonlinear optics. Brian’s research spans the general areas of quantum optics and quantum technologies and their use in probing fundamental quantum physics and realizing quantum-enhanced applications with performance beyond that possible with classical resources. In these fields he has developed approaches for producing non-classical states of light, methods to coherently manipulate quantum states of light, and efficient means to measure light. Recently his efforts have focused on harnessing the temporal-spectral mode structure of light to enable realization of larger quantum systems. These quantum-optical tools have enabled him to examine fundamental questions in quantum physics, such as the commutation relations for creation and annihilation operations, and experimentally address various quantum-enhanced technologies, for example quantum-enhanced sensing and quantum networking. He was elected Fellow of Optica (formerly Optical Society of America) in 2023.
