High Fidelity Cross Resonance Gates on Fixed Frequency Transmons

ORAL

Abstract

The performance of superconducting quantum computers is limited by two qubit gate fidelity. The fidelity of cross resonance gates in particular is limited by single qubit coherence times. In this presentation we benchmark a cross resonance gate between high-coherence transmons based on tantalum.
