Large, Individually-addressable, Multispecies Quantum Information Processor : Performance

ORAL

Abstract

Under the IARPA LogiQ program, in a collaboration between universities and industrial partners, we have constructed a complex ion-based quantum processor with the goal of realizing a logical quantum bit. I will report on the performance of our first-generation integrated system, including fidelities of single-qubit and two-qubit gates, crosstalk, operation with long ion chains, syndrome readout and multi-species operation.
