South Dakota Mines Receives $5 Million to Support Quantum Information Science

 A team of South Dakota Mines researchers received a $5 million grant from the National Science Foundation (NSF) to establish a Quantum Materials Institute on campus to advance quantum computing and secure quantum communications.

The Institute, a collaboration with the NSF-funded MonArk Quantum Foundry, will provide research funding and equipment focused on the discovery and development of compact, efficient nonlinear optical systems built from atomically thin 2D materials and sub-wavelength flat optics, also known as metasurfaces. These optical systems are expected to find application in chip-scale integrated photonics and quantum networks and boost the university's efforts to advance quantum information science (QIS), said Steve Smith, Ph.D., head of the Department of Nanoscience and Biomedical Engineering and principal investigator on the project.

Drs. Robert Anderson, Shan Zhou and Mingyuan Chen, faculty from nanoscience and biomedical engineering, Tula Paudel from physics and Alexey Lipatov from chemistry, biology, and health sciences are co-investigators on the project. The team will bring their expertise in the synthesis, characterization, and theoretical analyses of a palette of 2D materials and metasurfaces to pursue a fundamental understanding of materials and systems optimized for second harmonic generation and parametric down-conversion, two important nonlinear optical processes in quantum communication networks based on entangled photons.

QIS includes efforts to develop quantum computers, sensors and secure communication networks, all of which have an advantage over classical counterparts due to the intrinsic properties of quantum mechanics, Smith said.

“Currently, QIS is a cutting-edge research area supported by federal funding agencies, but a growing industry and emerging job market are taking this research and putting it into practice. I’ve been told Intel can’t find enough U.S. graduates trained in QIS, so there’s an opportunity for South Dakota Mines to serve this industry.”

The recent $5 million grant is a big step toward the university establishing a robust and sustained QIS effort, building on the teams’ two previous NSF awards, totaling more than $1.8M. Last year, Mines received a $50,000 quantum mechanics laboratory kit from industry pioneer Qubitekk to be used by students in a series of new courses on quantum materials, nanophotonics, quantum computing and quantum communications, offered this year by Smith and Anderson.

In support of their research in low-dimensional quantum materials — a part of the MonArk Quantum Foundry  and the Quantum Materials Institute — Smith and Anderson conceived the courses to give engineering and science majors practical training in quantum materials, quantum computing and quantum communications.

Funding for the Quantum Materials Institute will enable the university to expand its quantum curriculum, adding to its recently approved graduate and undergraduate certificates in quantum communications and a planned minor in QIS.
