Induced random mixed states are symmetric Dirichlet mixtures

Brian T. Kirby, Alexander C. B. Greenwood, Sanjaya Lohani +1

We establish an exact equivalence in distribution between -dimensional random mixed states induced by partial traces over -dimensional environments and the Mai-Alquier distri…

A Universal Entanglement Witness Generator

Aiden R. Rosebush, Alexander C. B. Greenwood, Andi Shahaj +1

Entanglement witnesses are essential for certifying entanglement, yet constructing ones that are both noise-robust and economical in measurement settings remains challenging - part…

Re-examining the Role of State Texture in Gate Identification and Fixed-Point Resource Theories

Alexander C. B. Greenwood, Joseph M. Lukens, Li Qian +1

A protocol for identifying controlled-NOT (CNOT) gates versus single-qubit-only gates in universal quantum circuits using randomized input states was recently shown to be intimatel…

Random Party Distillation on a Superconducting Processor

Alexander C. B. Greenwood, Jackson Russett, Hoi-Kwong Lo +1

Random party distillation refers to the process by which Einstein-Podolsky-Rosen pairs are probabilistically extracted from a single copy of a multipartite entangled state after mu…

An Exponential Reduction in Training Data Sizes for Machine Learning Derived Entanglement Witnesses

Aiden R. Rosebush, Alexander C. B. Greenwood, Brian T. Kirby +1

We propose a support vector machine (SVM) based approach for generating an entanglement witness that requires exponentially less training data than previously proposed methods. SVM…
