LocalMPSTensor

class mpsprep.mpsstatepreparation.LocalMPSTensor(tensor=None, left_bond_dim=None, right_bond_dim=None, physical_dim=None)

Bases: object

Cores of the tensor network. These are the tensors that are multiplied together to form the Matrix Product State (MPS).

__init__(tensor=None, left_bond_dim=None, right_bond_dim=None, physical_dim=None)

Initialize the tensor.

Parameters

tensornp.ndarray

The tensor.

left_bond_dimint

The left bond dimension.

right_bond_dimint

The right bond dimension.

physical_dimint

The physical dimension.

Methods

__init__([tensor, left_bond_dim, ...])	Initialize the tensor.
to_left_matrix()	Convert to a left matrix.
to_right_matrix([order])	Convert to a right matrix.

Attributes
