Enhancing Entanglement Purification with Shared Randomness

Allen Zang, Bikun Li, Xinan Chen +4

Entanglement purification protocols (EPPs) are essential for improving entanglement fidelity to support fault-tolerant distributed quantum information processing. Practical entangl…

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…

Entropic and operational characterizations of dynamic quantum resources

Kaiyuan Ji, Eric Chitambar

We offer new methods for characterizing general closed and convex quantum resource theories, including dynamic ones, based on entropic concepts and operational tasks. We propose a…

A resource theory of asynchronous quantum information processing

Chloe Kim, Eric Chitambar, Felix Leditzky

In standard quantum teleportation, the receiver must wait for a classical message from the sender before subsequently processing the transmitted quantum information. However, in po…

Capacities of Entanglement Distribution From a Central Source

Xinan Chen, Stefano Chessa, Ian George +2

Distribution of entanglement is an essential task in quantum information processing and the realization of quantum networks. In our work, we theoretically investigate the scenario…

Random Distillation Protocols in Long Baseline Telescopy

Yunkai Wang, Eric Chitambar

In quantum-enhanced astronomical imaging, multiple distant apertures work together by utilizing quantum resources distributed from a central server. Our findings suggest that pre-p…
