Isometrization of Tensor Network States via Gauge Propagation
Zhiyu Jiang, Hiroshi Ueda
We introduce a gauge-propagation approach for approximately converting generic tensor-network states into an isometric tensor-network form with a prescribed orthogonality center. I…

High-Precision Variational Quantum SVD via Classical Orthogonality Correction
Shohei Miyakoshi, Takanori Sugimoto, Tomonori Shirakawa +2
Evaluating the entanglement spectrum is essential for characterizing exotic quantum phases such as quantum criticality and topological order. However, for large quantum many-body s…
