When a quantum system initialized in a product state is subjected to either coherent or
incoherent dynamics, the entropy of any of its connected partitions generically increases as …

We consider the problem of symmetry decomposition of the entanglement negativity in free
fermionic systems. Rather than performing the standard partial transpose, we use the partial …

We study the growth of entanglement between two adjacent regions in a tripartite, one-
dimensional many-body system after a quantum quench. Combining a replica trick with a …

The entanglement properties of random pure states are relevant to a variety of problems
ranging from chaotic quantum dynamics to black-hole physics. The averaged bipartite …

We study the logarithmic entanglement negativity of symmetry-protected topological (SPT)
phases and quantum critical points (QCPs) of one-dimensional noninteracting fermions at …

In the context of ground states of quantum many-body systems, the locality of entanglement
between connected regions of space is directly tied to the locality of the corresponding …

Decoherence is a major obstacle to the preparation of topological order in noisy
intermediate-scale quantum devices. Here, we show that decoherence can also give rise to …

We discuss multipartitions of the gapped ground states of (2+ 1)-dimensional topological
liquids into three (or more) spatial regions that are adjacent to each other and meet at points …

We propose a diagnostic for finite temperature topological order using “topological
entanglement negativity,” the long-range component of a mixed-state entanglement …

We study quantum information aspects of the fermionic entanglement negativity recently
