Locally Purified Maximally Mixed States At Scale: Entanglement Pruning and Symmetries
Amit Jamadagni, Eugene Dumitrescu
Locally Purified Density Operators (LPDOs) are state-of-the-art tensor network ansatze candidates that efficiently represent mixed quantum states at scale. However, given their non…

Composite-Dimensional Topological Codes with Boundaries and Defects
Mohamad Mousa, Amit Jamadagni, Eugene Dumitrescu
We introduce new algorithms and provide example constructions of stabilizer models for the gapped boundaries, domain walls, and defects of Abelian composite-dimensional twiste…
