Quantum Analyzer ModuleΒΆ

The Quantum Analyzer (QA) module corresponds to the Quantum Analyzer Result Logger tab of LabOne user interface (UI). This nodule allows the user to record multiple measurement shots in its history tab and to apply matrix transformations on the measured complex signals, i.e. $I$ and $Q$ components obtained by weighted integration. It applies transform operations on the measured signals with the following order.

  • Shift or translation
  • Rotation
  • Scaling or dilation

The transform parameters are set by the module nodes and displayed in the control sub-tab of the QA tab in LabOne UI. The equivalent transformed outcome is obtained by matrix multiplication of the corresponding operators as shown in the following equation:

$$ \begin{pmatrix} X \\ Y \\ \end{pmatrix} = \begin{bmatrix} S_I & 0 \\ 0 & S_Q \\ \end{bmatrix} \begin{bmatrix} \cos\theta & -\sin\theta \\ \sin\theta & \cos\theta \\ \end{bmatrix} \begin{pmatrix} I-I_0 \\ Q-Q_0 \\ \end{pmatrix} $$

where $I_0$ and $Q_0$ are shift parameters, $\theta$ is rotation angle in degree, and $S_I$ and $S_Q$ are scaling factors. All the measurement shots are recorded in the History sub-tab of the QA tab and can be saved in CSV, HDF5, and MATLAB formats.
