Destroying and Preserving Measurement Incompatibility over a Quantum Channel
Eric Chitambar, Yujie Zhang
A quantum channel is called incompatibility-breaking if it always destroys the incompatibility of quantum measurements. On the other extreme are incompatibility-preserving channels…
Universal Improvement of Channel Fidelity via Entanglement Assistance
Xinan Chen, Eric Chitambar
Communication using quantum channels generally requires encoding and decoding on many identical uses of a quantum channel. In practical settings, decoherence may severely limit our…
Compatibility of quantum instruments
Chloe Kim, Yujie Zhang, Eric Chitambar +2
Measurement compatibility asks whether a family of quantum measurements can be simulated by one parent measurement followed by classical post-processing. We extend this measurement…
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…
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…
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…
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…
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…
