Abstract: Today’s quantum computers typically encode information in two states (qubit) embedded in the larger Hilbert space of some quantum system such as an atom, a photon, or a nonlinear circuit. To perform quantum error correction, they encode logical qubits as highly-entangled states of multiple information carriers. By expanding our control toolbox, we can make use of more of the energy levels (d>2 qudit) naturally available in our system of choice, trapped atomic calcium ions. This enables more efficient computation, simulation of higher-dimensional systems, and error correction within a single ion. We will discuss the development and demonstration of new techniques for efficient qudit manipulation and error-bias engineering.

Bio: Jameson O'Reilly is a postdoctoral scholar at the University of Oregon. He received his PhD from Duke University, where he worked on quantum networking with trapped ions.

Before the talk (~3:45pm), tea and coffee will be served outside 149 Weniger.

After the talk, there will be a reception with food and drink in 247 Weniger.
