Qubit Demonstrations at Frequencies Above Ten Gigahertz

ORAL

Abstract

Typical superconducting quantum information technologies are designed to operate in the 4 GHz to 8 GHz frequency range. Yet, there are advantages to operating at higher frequencies. Namely, there are less stringent constraints on cryogenic operating temperature as well as area scaling advantages. We present our designs and measurement results on higher frequency qubits and associated electronics, including a systematic study of materials losses, qubit designs, and measurement challenges. We focus on frequencies from 10 GHz to 30 GHz, and present a roadmap to achieving higher frequency qubits operating at temperatures approaching 1 K . Additionally, we report on schemes to up-convert control signals from lower frequencies using kinetic inductance structures.
