Building a Logical Qubit-sized Ion Trap Quantum Information Processor

ORAL

Abstract

We present the system design and architecture of a trapped ion universal quantum processor with high-fidelity quantum gates and addressing of up to 32 qubits. Our approach takes advantage of individual optical addressing to achieve simultaneous high-fidelity operations on a long chain of 171Yb+ ions, resulting in one of the largest academic general-purpose quantum computers. This framework enables long gate-depth, general-purpose algorithms, with the goal of demonstrating an error-corrected logical qubit. We will also cover advances we have made in the control system, specifically in canceling crosstalk and running long experiments.
