Fermionic Genuine Multiparty Entanglement
James Allen, Liuke Lyu, William Witczak-Krempa
Entanglement can show fundamentally different behavior in fermionic systems. However, while bipartite measures of fermionic entanglement have been established, genuine multiparty e…
Network-Irreducible Multiparty Entanglement in Quantum Matter
Liuke Lyu, Pedro Lauand, William Witczak-Krempa
We show that the standard approach to characterize collective entanglement via genuine multiparty entanglement (GME) leads to an area law in ground and thermal Gibbs states of loca…
Separability and entanglement of resonating valence-bond states
Gilles Parez, Clément Berthiere, William Witczak-Krempa
We investigate separability and entanglement of Rokhsar-Kivelson (RK) states and resonating valence-bond (RVB) states. These states play a prominent role in condensed matter physic…
Taming multiparty entanglement at measurement-induced phase transitions
Liuke Lyu, James Allen, Yi Hong Teoh +2
Measurement-induced phase transitions (MIPT) give rise to novel dynamical states of quantum matter realized by balancing unitary evolution and measurements. We present large-scale…
The Fate of Entanglement
Gilles Parez, William Witczak-Krempa
Quantum entanglement manifests itself in non-local correlations between the constituents of a system. In its simplest realization, a measurement on one subsystem is affected by a p…
Shape dependence of entanglement negativity and mutual information in quantum Hall and critical systems
Chia-Chuan Liu, Juliette Geoffrion, William Witczak-Krempa
We study two entanglement measures in a large family of isotropic many-body states including incompressible quantum Hall liquids and quantum critical systems: the logarithmic negat…
