+    The conversion is performed by QiboCircuitToEinsum(), after which it goes through 2 steps: pathfinder and execution.
     The pathfinder looks at user defined number of samples (n_samples) iteratively to select the least costly contraction path. This is sped up with multi thread.
     After pathfinding the optimal path is used in the actual contraction to give a dense vector representation of the TN.
