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.

Auxiliary vacuum chamber to test ion production by laser ablation assembled.

Nobel Laureate Dr. Bill Phillips visits Denison, presenting “Time, Einstein, and the Coolest Stuff in the Universe” to a packed house. He also met with classes, and engaged in discussions with students, faculty, and the community the following day.

Redesigned, and much improved, SHG cavity in operation. Special thanks to David Hanneke at Amherst College for discussing his cavity optimization calculations!

Kristina and Patrick present progress from the lab at DAMOP poster sessions.

Welcome to new IQO lab member Zach, and welcome back Patrick!

Liz, Kristina, and Jackie graduate from Denison University! Congratulations!

SHG cavity locked, producing blue light.

Four research students in the IQO lab this semester! Welcome back Patrick, Liz, Kristina, and Jackie.

The vacuum chamber is fully assembled (and baked), with pressure measured at about 10-11 torr.

Electron gun tested and ready.

Two independent study students in the lab this semester, and one senior researcher. Welcome back Patrick and Jackie, and welcome to new IQO lab member Kristina!

Patrick presents progress on spectroscopy in the hollow-cathode lamp at the Ohio College Research Symposium, held at Ohio Wesleyan University.
