QUANTUM PROCESSING UNIT

A quantum processing unit comprising : rows comprising first qubits and second qubits, the first qubits and the second qubits being arranged alternatingly within each row, the first qubits and the second qubits forming columns, respectively; a first source configured to drive the first qubits with a first Rabi frequency; a second source configured to drive the second qubits with a second Rabi frequency, wherein two adjacent qubits within each row are subject to a first two-qubit interaction; one in every two columns of first qubits comprises a first special qubit provided between two adjacent second qubits, the first special qubit being such that it is driven with at least twice the first Rabi frequency by the first source, and the first special qubit being subject to a second two-qubit interaction with respect to each of the two adjacent second qubits, and one in every two columns of second qubits contains one second qubit, named second special qubit, such that it is driven with at least twice the second Rabi frequency by the second source.
