Introduces witness E_NG whose ceiling bounds the Gaussian-irreducible Schmidt number, defining a hierarchy of non-Gaussian entanglement in continuous-variable systems.
An optimized pair-hopping term derived via third-order Schrieffer-Wolff transformation suppresses doublon transport through destructive interference, producing near-complete dynamical arrest in 1D and prethermal density-wave order in the many-body regime.
A multipartite pure state is 2-producible if and only if all generalized entanglement of purification gaps vanish.
Entanglement is certified if any three PT moments satisfy p_l > p_k^x p_m^{1-x} with x=(m-l)/(m-k), and quantum weight enumerators describe moment decay under local noise.
Symmetric random induced states yield PPT bound entanglement with probability close to 1 for N>3 qubits via two partial tracing constructions.
Time evolution of genuine multipartite negativity in the open Kitaev quantum spin liquid shows persistence in loopy subregions in Markovian regime and at higher temperatures in non-Markovian regime.
A quantum channel A is physically harder to implement than channel B if A's output statistics allow unique identification of the input state from B's output via some measurement, which is equivalent to obtaining A from B by post-composition with an HPTP map.

Fate of entanglement in open quantum spin liquid: Time evolution of its genuine multipartite negativity upon sudden coupling to a dissipative bosonic environment

Comparing quantum channels using Hermitian-preserving trace-preserving linear maps: A physically meaningful approach
A quantum channel A is physically harder to implement than channel B if A's output statistics allow unique identification of the input state from B's output via some measurement, which is equivalent to obtaining A from B by post-composition with an HPTP map.
