1. A quantum information control method comprising:
generating a control signal configured to modulate, at a modulation frequency, a transition frequency of a tunable qubit device in a quantum processor, the modulation frequency being determined based on a transition frequency of a fixed-frequency qubit device in the quantum processor, the transition frequency of the fixed-frequency qubit device being independent of a magnetic flux experienced by the fixed-frequency qubit device; and
applying a two-qubit quantum logic gate to a pair of qubits in the quantum processor by communicating the control signal to a control line coupled to the tunable qubit device, the pair of qubits comprising a first qubit defined by the fixed-frequency qubit device and a second qubit defined by the tunable qubit device,
wherein applying the two-qubit quantum logic gate to the pair of qubits comprises one of the following:
applying an iSWAP gate to the pair of qubits;
applying a square-root-of-iSWAP gate to the pair of qubits;
applying a controlled-Z gate to the pair of qubits; or
applying a Bell-Rabi gate to the pair of qubits.
