Abstract Quantum processor architectures must enable scaling to large qubit numbers while providing two-dimensional qubit connectivity and exquisite operation fidelities. For microwave-controlled semiconductor spin qubits. dense arrays have made considerable progress. but are still limited in size by wiring fan-out and exhibit significant crosstalk between qubits. https://www.itsmajorlook.com/great-deal-Chicago-Cubs-Earrings-Round-Design-p21310-limited-grab/
