Rényi Phase Transitions and Analytic Continuation to the von Neumann Entropy
Ayush Raj, Akash Vijay, Hong-Chen Jiang +1
Extracting operationally meaningful quantities such as von Neumann entropy and mutual information is central to characterizing many-body quantum systems, yet experiments and numeri…

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…

Rényi mutual information in quantum field theory, tensor networks, and gravity
Jonah Kudler-Flam, Laimei Nie, Akash Vijay
We explore a large class of correlation measures called the Rényi mutual informations (RMIs). Unlike the commonly used notion of RMI involving linear combinations of Rényi en…
