seemps.state.MPS#
- class seemps.state.MPS(data, error=0)[source]#
MPS (Matrix Product State) class.
This implements a bare-bones Matrix Product State object with open boundary conditions. The tensors have three indices, A[α,d,β], where α,β are the internal labels and d is the physical state of the given site.
- Parameters:
- data
Iterable[Tensor3] Sequence of three-legged tensors A[α,si,β]. The dimensions are not verified for consistency.
- error
float, default=0.0 Accumulated truncation error in the previous tensors.
