Playing Nonlocal Games with Little to No Shared Randomness
Mingze Xu, Eric Chitambar
Bell nonlocality reveals correlations that cannot be explained by classical models and plays a central role in quantum information theory. In this work, we investigate classical mo…
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…
InterQnet: A Heterogeneous Full-Stack Approach to Co-designing Scalable Quantum Networks
Joaquin Chung, Daniel Dilley, Ely Eastman +21
Quantum communications have progressed significantly, moving from a theoretical concept to small-scale experiments to recent metropolitan-scale demonstrations. As the technology ma…
One-Shot Distributed Source Simulation: As Quantum as it Can Get
Ian George, Min-Hsiu Hsieh, Eric Chitambar
Distributed source simulation is the task where two (or more) parties share some correlated randomness and use local operations and no communication to convert this into some targe…
Cost of Simulating Entanglement in Steering Scenario
Yujie Zhang, Jiaxuan Zhang, Eric Chitambar
Quantum entanglement is a fundamental feature of quantum mechanics, yet certain entangled states that are unsteerable can be classically simulated in steering scenarios, making the…
Exploring Non-Multiplicativity in the Geometric Measure of Entanglement
Daniel Dilley, Jerry Chang, Jeffrey Larson +1
The geometric measure of entanglement (GME) quantifies how close a multi-partite quantum state is to the set of separable states under the Hilbert-Schmidt inner product. The GME ca…
