Title
Increasing Qubit Count and Connectivity Without Sacrificing Fidelity
Abstract
Trapped ions are a leading platform for quantum information processing with long coherence times and high fidelity and fast gates. Ions trapped in the same harmonic share quantized modes that can be used to mediate all-to-all connectivity. In practice, however, quantum information processing with long ion chains suffers from increased errors. These errors are often overlooked in proof-of-principle experiments, but will be showstoppers for megaQubit scale quantum technologies. In this talk we will discuss two such error sources and ways to reduce them: (1) collisions with background gas molecules and (2) optical crosstalk between control beams.
Bio
Sara Mouradian is an Assistant Professor of Electrical and Computer Engineering at the University of Washington, Seattle. She received her B.S., M.Eng., and Ph.D. degrees from the Massachusetts Institute of Technology where she worked on quantum technologies in optical and solid-state systems. She was then an Intelligence Community Postdoctoral Fellow at the University of California, Berkeley where she helped to demonstrate control over rotational modes of ions and demonstrated a new sensing technique capable of showing real quantum advantage. At UW her lab focuses on trapped ion quantum information processing including optical control with integrated photonics, optimization of multi-qubit gates, and fabrication of next generation trap designs. In addition to her research work, she is passionate about educating students of all ages and backgrounds about science.
