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…
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…
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…
Entanglement architecture of beyond-Landau quantum criticality
Menghan Song, Ting-Tung Wang, Liuke Lyu +2
Quantum critical points beyond the Landau paradigm exhibit fractionalized excitations and emergent gauge fields. Here, we use entanglement microscopy--full tomography of the reduce…
Spatial structure of multipartite entanglement at measurement induced phase transitions
James Allen, William Witczak-Krempa
We study multiparty entanglement near measurement induced phase transitions (MIPTs), which arise in ensembles of local quantum circuits built with unitaries and measurements. In co…
Multiparty entanglement loops in quantum spin liquids
Liuke Lyu, Deeksha Chandorkar, Samarth Kapoor +3
Quantum spin liquids (QSLs) give rise to exotic emergent particles by weaving intricate entanglement patterns in the underlying electrons. Bipartite measures between subregions can…
