TITLE: "Mastering the Infinite: Phonons and Qudits for the Next-Generation Trapped-Ion Quantum Processor”
ABSTRACT: I will present recent advancements in the state-of-the-art trapped-ion platform, configured as a linear array with individual addressability. This system enables high-fidelity two-qubit gates via common motional modes, a key component for universal quantum computing. At the same time, its advanced control capabilities allow for fully programmable analog quantum simulation. This versatility has enabled a broad range of applications, including high-energy physics simulations, Hamiltonian learning, and more.

Next, I will discuss extending beyond qubits to multilevel quantum systems—qudits—which can be implemented in various ways within a trapped-ion array. I will compare these approaches, examining their advantages, challenges, and potential applications in fundamental physics. Finally, I will explore the scalability of trapped-ion systems and their prospects for large-scale quantum computing. Ultimately, the trapped-ion platform stands out for its ability to seamlessly transition between a programmable analog quantum simulator and a universal quantum computer, making it a powerful tool for advancing quantum science and technology.
