Quantum Control of Trapped-Ions via Integrated Photonics

Dr. Jeremy Sage, MIT Lincoln Laboratory, Lexington, MA


Dr. Jeremy Sage, MIT Lincoln Laboratory, Lexington, MA

Abstract:  Trapped-ions are one of the most promising qubit modalities for realizing practical quantum computers and quantum sensors.  Ion qubits are typically controlled and measured using lasers delivered with free-space optics, an approach which works well for small and/or laboratory-based systems, but one that presents challenges to scaling and portability.  Delivery of light to trapped ions via photonics integrated into chip-scale ion traps is another approach, which offers the potential to overcome some of these challenges.  In this presentation, I will discuss the basics of trapped-ion quantum computing and sensing and the technological demands of trapped-ion quantum systems.  I will then discuss the development and performance of an integrated-photonics platform that functions over a wavelength range from the near ultraviolet to the near infrared which is aimed at meeting many of these demands, as well as demonstrations of trapped-ion quantum control and readout using this platform.


Biography:  Dr. Jeremy Sage is a senior staff member in the Quantum Information and Integrated Nanosystems Group at MIT Lincoln Laboratory, where he co-leads the trapped-ion quantum information processing projects, and is a Principal Investigator in the Research Laboratory of Electronics at MIT.  His current research is focused on the science and engineering of trapped-ion and integrated-photonic systems for quantum information processing.  Dr. Sage received a B.S in Physics/Mathematics from Brown University and a Ph.D. in Physics from Yale University.
