  • Publication number: 20240086752
    Abstract: A device includes a first set of circuit components implementing a qubit and a second set of circuit components implementing a readout resonator for reading out a state of the qubit. A first footprint of the first set of circuit components overlaps a second footprint of the second set of circuit components. The first footprint is oriented relative to the second footprint based on a first electric dipole of the first set of circuit components and a second electric dipole of the second set of circuit components.
