The anatomy of a quantum LEGO

A quantum LEGO has the following pieces in PlanqTN:

  • a body that might be a generic or special design (see Predefined tensors for a detailed list of them)
  • an instance ID (12 in the figure above) - an integer in the UI, though the TensorId is a richer object in the PlanqTN Python library
  • a short name (T6 in the figure above) - this can be changed in the Details panel or the Floating subnet toolbar
  • physical legs with leg labels (legs 0, 1, 2, 3 in the figure)
  • logical legs with leg labels (legs 4 and 5 in the figure) - these are clickable for highlighting
  • Pauli highlights - gray/no highlights for I, red for X, blue for Z and purple for Y operators

One can hide or show any of these details by changing the Canvas menu > display settings options.
