seemps.state.CanonicalMPS.entanglement_entropy

method

CanonicalMPS.entanglement_entropy(site=None)

Compute the entanglement entropy of the MPS for a bipartition around site.

Parameters:

siteint, optional

Site in the range [0, self.size), defaulting to self.center. The system is diveded into [0, self.site) and [self.site, self.size).

Returns:

float

Von Neumann entropy of bipartition.
