Ion Quantum Optics

Welcome to Steven Olmschenk's Ion Quantum Optics group. This research lab is part of the Department of Physics and Astronomy at Denison University in Ohio.

Our research is focused on the quantum interface between matter and light. Towards this end, we are exploring novel techniques to integrate single trapped atomic ions with single photons, with a focus on applications in quantum information. In addition, these investigations may yield new insight in atomic physics and quantum optics, including a better understanding of the fundamental role of decoherence and measurement in each of these systems.

Also included on this site is relevant information about specific topics in atomic, molecular, and optical physics.

We gratefully acknowledge funding support from the:

National Science Foundation

and previous funding support from the Army Research Office, Research Corporation, and Denison University.


After a successful tenure review, Dr. Olmschenk is officially promoted to Associate Professor (with tenure).

Welcome to new IQO lab members Cornelia and Rahul!

Patrick graduates from Denison University! Congratulations! He also appeared in a video where graduating seniors share some reflections on their time at Denison, and plans for the future.

Dr. Olmschenk is awarded a CAREER grant from the National Science Foundation! The grant is distributed over five years, and includes support for permanent equipment, supplies, undergraduate student researchers, and curricular development.

Patrick is awarded the prestigious National Science Foundation Graduate Research Fellowship! Congratulations Patrick!
