This tab shows the raw GST estimates — the density matrices, POVM effects, and process matrices that comprise the estimated gateset. These are explicitly gauge-dependent, and most reports include multiple gauge optimizations
that correspond to slightly different (but physically equivalent and indistinguishable) representations of the operations. Usually, these raw estimates are less useful than the derived properties and decompositions shown elsewhere, but sometimes it's useful to see them. Furthermore, it's possible (at least in some versions of the report) to download the raw gateset in machine-readable form, in order to do calculations and simulations with it.
targetlogic gates. Each gate is represented as a d^2\times d^2 superoperator that acts by matrix multiplication on vectors in the vector space \mathcal{B}(\mathcal{H}) of operators. Matrices are displayed using a heat map that ranges between 1.0 (red) and -1.0 (blue), and hovering the pointer over a matrix element will pop up its precise numerical value. Note that it is impossible to discern even order-1%% deviations from the ideal in this view; that's what other analyses (especially the Gate Error Generators tab) are for.
