A periodic Matrix Product State (MPS) for a quantum state of discrete degrees of freedom, wrapped as Jax machine.
The MPS is defined as
\[\Psi(s_1,\dots s_N) = \mathrm{Tr} \left[ A[s_1]\dots A[s_N] \right] ,\]for arbitrary local quantum numbers \(s_i\), where \(A[s_1]\) is a matrix of dimension (bdim,bdim), depending on the value of the local quantum number \(s_i\).
