Product testing with single-copy measurements

Jacob Beckey, Luke Coffman, Ariel Shlosberg +2

In this work, we study the sample complexity of two variants of product testing when restricted to single-copy measurements. In particular, we consider both bipartite product testi…

An Operational Framework for Nonclassicality in Quantum Communication Networks

Brian Doolittle, Felix Leditzky, Eric Chitambar

Quantum resources, such as entanglement or quantum communication, offer significant communication advantages in information processing. We develop an operational framework for real…

Localizing multipartite entanglement with local and global measurements

Christopher Vairogs, Samihr Hermes, Felix Leditzky

We study the task of localizing multipartite entanglement in pure quantum states onto a subsystem by measuring the remaining systems. To this end, we fix a multipartite entanglemen…

Approximate Unitary -Designs from Shallow, Low-Communication Circuits

Nicholas LaRacuente, Felix Leditzky

Random unitaries are useful in quantum information and related fields, but hard to generate with limited resources. An approximate unitary -design is an ensemble of unitaries wi…

On the distinguishability of geometrically uniform quantum states

Juntai Zhou, Stefano Chessa, Eric Chitambar +1

A geometrically uniform (GU) ensemble is a uniformly weighted quantum state ensemble generated from a fixed state by a unitary representation of a finite group . In this work we…

Improving quantum communication rates with permutation-invariant codes

Sujeet Bhalerao, Felix Leditzky

In this work we improve the quantum communication rates of various quantum channels of interest using permutation-invariant quantum codes. We focus in particular on parametrized fa…
