High-Dimensional Qudit Control in Trapped Ions for Quantum Computing and Quantum Simulation

Explore cutting-edge research on high-dimensional qudit control in trapped ions for quantum computing and quantum simulation in this 29-minute conference talk by Crystal Senko from the Institute for Quantum Computing. Delve into ongoing experimental work on preparing, reading out, and controlling large qudits (up to 25 levels) encoded in Ba-137+ ions. Examine the experimental challenges involved in simultaneously controlling 9+ quantum states and learn about recent achievements in high-fidelity state preparation and measurement (SPAM) of a 25-level qudit. Gain insights into preliminary work on control and diagnostics of coherent superposition states, crucial for utilizing high-dimensional quantum resources in computation and quantum simulation. Conclude by considering open questions relevant to the further development of qudit-based quantum processors.
