Abstract: In a general aspect, two-qubit quantum gate operations are performed in a superconducting quantum processing unit. In some cases, a flux modulation signal is generated. The flux modulation signal is configured to modulate a transition frequency of a first tunable-frequency qubit device in a superconducting quantum processing unit such that a time average of the transition frequency of the first tunable-frequency qubit device over a duration of the flux modulation signal is on resonance with a transition frequency of a second qubit device in the superconducting quantum processing unit. A two-qubit quantum logic gate is applied to a pair of qubits defined by the first tunable-frequency qubit device and the second qubit device. Applying the two-qubit quantum logic gate includes communicating the flux modulation signal to a flux bias control line coupled to the first tunable-frequency qubit device.

Abstract: In a general aspect, quantum control is performed by modulating tunable devices in a superconducting circuit. In some implementations, values of parameters for a control signal are identified. The control signal is to apply a control operation to a qubit defined by a tunable qubit device in a superconducting quantum processing unit. The control signal is generated according to the values of the parameters. The control signal includes a plurality of modulation tones. The control operation is applied to the qubit by delivering the control signal to a flux bias device associated with the tunable qubit device. The control signal controls a magnetic flux applied to the tunable qubit device by the flux bias device and renders the qubit insensitive to flux noise.
