jet.bindings.TensorNetworkC128¶

class TensorNetworkC128¶

Bases: pybind11_builtins.pybind11_object

TensorNetwork represents a tensor network.

Attributes

`dtype`
`index_to_edge_map`	Mapping from indices to edges.
`nodes`	List of nodes in this tensor network.
`num_indices`	Number of unique indices in this tensor network.
`num_tensors`	Number of tensors in this tensor network.
`path`	Path by which this tensor network was contracted.
`tag_to_node_id_map`	Mapping from tags to node IDs.

path¶: Path by which this tensor network was contracted. Is empty if Contract() has not been called.

`add_tensor`(self, tensor, tags)	Adds a tensor to a tensor network.
`contract`(self, path, int]] = [])	Contracts a tensor network along an optionally-provided path.
`slice_indices`(self, arg0, arg1)	Slices a set of indices.

add_tensor(self: jet.bindings.TensorNetworkC128, tensor: jet.bindings.TensorC128, tags: List[str] = []) → int¶

Adds a tensor to a tensor network.

Parameters

Returns

Node ID assigned to the tensor.

Return type

int

contract(self: jet.bindings.TensorNetworkC128, path: List[Tuple[int, int]] = []) → jet.bindings.TensorC128 ¶

Contracts a tensor network along an optionally-provided path.

Parameters: path (Optional[Tuple[str, str]]) – Optional contraction path specified as a list of node ID pairs.
Returns: Tensor associated with the result of the final contraction.
Return type: Tensor

slice_indices(self: jet.bindings.TensorNetworkC128, arg0: List[str], arg1: int) → None¶

Slices a set of indices. The value taken along each axis is derived from the provided linear index.

Parameters

indices (List[str]) – List of string indices to be sliced.
value (int) – Raveled index value representing the element to take along each of the indices.
