High-dimensional qudit control in trapped ions for quantum computing and quantum simulation

Crystal Senko from IQC presents at the QuDits for Quantum Technology workshop, hosted by the Quantum Interactions Theory Group at the Institute for Quantum Computing, University of Waterloo. Learn more: https://quantum-interactions.com/

In this talk, I will present ongoing experimental work on the preparation, readout, and control of large qudits (up to d=25 levels) encoded in Ba-137+ ions. I will discuss experimental challenges in the simultaneous control of 9+ quantum states, and present recent results on high-fidelity state preparation and measurement (SPAM) of a 25-level qudit. I will also discuss our preliminary work on control and diagnostics of coherent superposition states, which we anticipate to be a key prerequisite to use these high-dimensional quantum resources for computation and quantum simulation. As an outlook, I will highlight some open questions relevant to the further development of qudit-based quantum processors.
