When it comes to quantum physics, light and matter are not so different. Under certain circumstances, negatively charged electrons can fall into a coordinated dance that allows them to carry a current through a material laced with imperfections. That motion, which can only occur if electrons are confined to a two-dimensional plane, arises due to a phenomenon known as the ...

Jay Deep Sau, an assistant professor of physics at the University of Maryland and fellow of the Joint Quantum Institute, was awarded a Sloan Research Fellowship for 2016. This award, granted by the Alfred P. Sloan Foundation, identifies 126 early-career scientists based on their potential to contribute fundamentally significant research to a wider academic community.

Jay Deep Sau, an assistant professor of physics at the University of Maryland and fellow of the Joint Quantum Institute, received a Faculty Early Career Development (CAREER) Award from the National Science Foundation (NSF) for his proposal titled “Topologically Protected Quantum Devices.” Sau, a theoretical condensed matter physicist interested in applying topological principles to create protected solid-state and cold-atomic systems ...

Harnessing quantum systems for information processing will require controlling large numbers of basic building blocks called qubits. The qubits must be isolated, and in most cases cooled such that, among other things, errors in qubit operations do not overwhelm the system, rendering it useless. Led by JQI Fellow Christopher Monroe, physicists have recently demonstrated important steps towards implementing a proposed ...
