Optimal bound on long-range distillable entanglement
Jonah Kudler-Flam, Vladimir Narovlansky, Nikita Sopenko
We prove an upper bound on long-range distillable entanglement in spatial dimensions. Namely, it must decay faster than , where is the distance between entangled regio…

A classification of phases of bosonic quantum lattice systems in one dimension
Anton Kapustin, Nikita Sopenko, Bowen Yang
We study invertible states of 1d bosonic quantum lattice systems. We show that every invertible 1d state is in a trivial phase: after tensoring with some unentangled ancillas it ca…
