Systems and devices for quantum processor topology

Abstract

Topologies for analog processors may include cells comprising at least portions of qubits and couplers. Qubits and couplers may be shared among or extend across multiple cells. A cell may include four sets of partial qubits, and partial qubits may form whole qubits with partial qubits in adjacent cells. First and second sets of partial qubits may include partial qubits that extend substantially parallel to one another and along a first direction. Third and fourth sets may include partial qubits that extend substantially parallel to one another and along a second direction. Each partial qubit in the first and second sets may cross, and be substantially orthogonal to, at least one partial qubit from each of the third and fourth sets. A cell may include first and second sets of intra-cell couplers, and partial couplers that form inter-cell couplers with partial couplers in adjacent cells.
