Atomic flux pulses for a superconducting quantum processor, part 1: real-time corrections and repeatability of flux pulses

ORAL

Abstract

We present the calibration and characterization of atomic, repeatable flux pulses compatible with a flexible Quantum Instruction Set Architecture (QISA). The flux pulses take advantage of distortion corrections realized by real-time filtering in the arbitrary waveform generator as the sequence of pulses is executed, rather than conventional pre-distortion of the waveform shape in software. We combine the corrections with the net-zero waveform shape and quantify the repeatability of flux pulsing. The phases acquired by the qubit in each of two consecutive flux pulses match within 1 deg, independent of the delay between them.
