Speaker: Will Oliver Host: Zlatko Minev, Ph.D. Title: Quantum Engineering of Superconducting Qubits Abstract: In this talk, we present recent results related to quantum engineering of superconducting qubits. We begin with the noise spectroscopy of superconducting qubits. We discuss spatiotemporal noise spectroscopy of two qubits (cross-spectrum), the impact of higher energy states beyond a two-level approximation on spin locking, and the measurement of non-Gaussian noise. We then discuss our latest two-qubit gate fidelity demonstrations that use a tunable coupler to achieve iSWAP and CZ two-qubit interaction fidelities approaching 99.9%. -- The Quantum Computing Seminar Series is a deep dive into various academic and research topics within the quantum community. It will feature community members and leaders every Friday, 12 PM EDT.
