tlquantum.tt_precontraction.layers_contract

tlquantum.tt_precontraction.layers_contract(layer_list, ncontrl)[source]

Contracts sublists of a list of layers vertically (merging cores of multiple layers for a single qubit) up to some maximum contraction depth.

Parameters:

layer_listList of tt-tensor layers

ncontrlMaximum number of layers to contract into each composite layer.

Returns:

List of layers resulting from vertically contracting the layers of layer_list
