1. A method comprising:
operating a first qubit in a system of qubits at a first qubit frequency within a first qubit frequency region, wherein the first qubit frequency region covers a first range of frequencies;
operating a second qubit in the system of qubits at a second qubit frequency within a second qubit frequency region, wherein the second qubit frequency region covers a second range of frequencies, the second qubit frequency and the second qubit frequency region being different from the first qubit frequency and the first qubit frequency region; and
operating a third qubit in the system of qubits at a third qubit frequency from the second qubit frequency region, the third qubit frequency being different from the first qubit frequency and the second qubit frequency, wherein
the third qubit is different from the second qubit and the third qubit frequency differs from the second qubit frequency by a frequency that is larger than a coupling strength between neighboring qubits in the system of qubits.
