Abstract

An embodiment of a qubit tuning device includes a first layer configured to generate a magnetic field, the first layer comprising a material exhibiting superconductivity in a cryogenic temperature range. In an embodiment, the qubit tuning device includes a qubit of a quantum processor chip, wherein the first layer is configured to magnetically interact with the qubit such that a first magnetic flux of the first layer causes a first change in a first resonance frequency of the qubit by a first frequency shift value.
