Comparing bipartite entropy growth in open-system matrix-product simulation methods
Guillermo Preisser, David Wellnitz, Thomas Botzung +1
The dynamics of one-dimensional quantum many-body systems is often numerically simulated with matrix-product states (MPSs). The computational complexity of MPS methods is known to…

Rise and fall, and slow rise again, of operator entanglement under dephasing
David Wellnitz, Guillermo Preisser, Vincenzo Alba +2
The operator space entanglement entropy, or simply 'operator entanglement' (OE), is an indicator of the complexity of quantum operators and of their approximability by Matrix Produ…
