Position Description:    

*** The account for LPS Qubit Collaboratory (LQC), Laboratory for Physical Sciences (LPS) has expired and new applications are no longer accepted. ***

The Laboratory for Physical Sciences (LPS, has an immediate vacancy for a postdoctoral researcher in its Quantum Information Science (QIS) research group. LPS seeks an experimental physicist, or other suitably qualified Ph.D., to study Reversible Digital Logic at its College Park, MD location, adjacent to the University of Maryland campus. LPS research has conducted theoretical studies [1, 2], one of which [2] was recently recognized with the 2021 Van Duzer award for the best contributed paper to the IEEE Transactions on Applied Superconductivity. The LPS approach to energy efficiency is based on the ballistic traversal of single-flux quanta (SFQ) into and through gates (with no power applied to the gates). Other potential advantages stem from the SFQ's two possible polarities for encoding a bit. The postdoctoral researcher will collaborate within the LPS' QIS group to perform measurements on custom reversible logic devices. More generally, this will advance the experimental understanding of Reversible Digital Logic [3]. LPS is a collaborative laboratory and the position offers opportunities for interaction with research centers at the University of Maryland Physics Department. Self-motivated candidates with a Ph.D. degree in physics or electrical engineering and experience in all or most of the following areas are invited to apply: SFQ logic, superconducting devices or circuits, RF design, custom electronic measurements, CAD, data acquisition programming, data analysis, simulation, QIS experiments, and microfabrication.

To apply, submit the following electronically to the attention of Dr. Kevin Osborn (,

 Cover Letter  Curriculum Vitae  List of Publications  Contact information for at least two references
