Abstract: Methods and apparatus for generating waveforms for application in a quantum computing device. In one aspect, a system comprises a batch generator that receives experiment data sets defining respective experiments, each experiment data set comprising a set of waveforms defined by respective waveform data; determines unique waveforms; generates a corresponding set of respective waveform data that includes the respective waveform data for each unique waveform; generates, for each of the experiments, a waveform list that references the respective waveform data in the set of respective waveform data that corresponds to the waveforms in the set; and batch instructions that are executable by waveform generator hardware and that cause the waveform generator hardware to process each waveform list by selecting each referenced waveform data in the waveform list; and generate, in response to the selected waveform data, a waveform that is suitable for application in a quantum computing device.

Abstract: Methods, systems and apparatus for dynamically decoupling and performing a target unitary operation to a qubit. In one aspect, a method includes generating a control signal that implements a dynamical decoupling control sequence and applying the control signal to the qubit to dynamically decouple the qubit and perform the target unitary operation on the qubit. The target unitary operation includes a product of multiple sub-unitary operations. The dynamical decoupling control sequence includes a plurality of single qubit gates, where one or more of the single qubit gates comprise a single qubit gate that implements one or more of sub-unitary operations of the multiple sub-unitary operations.
