Abstract
A quantum processor includes: a first chip comprising a qubit array, in which a plurality of qubits within the qubit array define an enclosed region on the first chip, in which each qubit of the plurality of qubits that define the enclosed region is arranged to directly electromagnetically couple to an adjacent qubit of the plurality of qubits that define the enclosed region, and in which each qubit of the qubit array comprises at least two superconductor islands, and a second chip bonded to the first chip, the second chip including one or more qubit control elements, in which the qubit control elements are positioned directly over the enclosed region of the first chip.
Claims16
A single qubit comprising:
- at least three superconductor islands on a first substrate, wherein only a first superconductor island and a second superconductor island of the at least three superconductor islands are coupled to a Josephson junction,
- wherein each remaining superconductor island, other than the first superconductor island and the second superconductor island, of the at least three superconductor islands lacks a direct electrical connection to each other island of the qubit.
