Logarithmic negativity typically equals exact entanglement cost
Bowen Ouyang, Jonah Kudler-Flam
Quantum entanglement plays a leading role in modern understanding of physical systems, from quantum phases of matter to quantum gravity. In quantum information theory, one seeks op…

Analytically Continuing the Randomized Measurement Toolbox
Akash Vijay, Ayush Raj, Jonah Kudler-Flam +3
We develop a framework for extracting non-polynomial analytic functions of density matrices in randomized measurement experiments by a method of analytical continuation. A central…

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…
