Network

The alice.network module provides the core tensor network data structures: MPS, MPO, Network, NormalMPO, and associated functions. These objects are re-exported at the top-level alice namespace.

Classes

Class	Description
Network	Base 1D tensor network chain
MPS	Matrix product state
MPO	Matrix product operator
NormalMPO	Unit-normed MPO with separately tracked scale factor

Functions

Function	Description
init_mps	Construct an initial MPS for DMRG
observe	Compute expectation value ⟨ψ|O|ψ⟩ or thermal average Tr[ρO]/Tr[ρ]
thermal_mpo	Approximate \(e^{-\beta H}\) via Taylor expansion
