Robust Entanglement Witnessing via Dense Network Coding with Graph States
Brian Doolittle, Ian George
Practical tests for witnessing entanglement in the presence of noise are needed to verify and apply entanglement-based applications in real-world communication networks. Quantum de…
Communication Advantages from Quantum Dense Network Coding
Ian George, Brian Doolittle
A central problem in quantum information theory is understanding how quantum resources can be used to communicate information more efficiently than classical resources. We introduc…
\textit{In Silico} Benchmarking of Detectable Byzantine Agreement in Noisy Quantum Networks
Mayank Bhatia, Shaan Doshi, Daniel Winton +3
Quantum communication resources offer significant advantages for fault-tolerant distributed protocols, particularly in Byzantine Agreement (BA), where reliability against adversari…
Realistic quantum network simulation for experimental BBM92 key distribution
Michelle Chalupnik, Brian Doolittle, Suparna Seshadri +8
Quantum key distribution (QKD) can provide secure key material between two parties without relying on assumptions about the computational power of an eavesdropper. QKD is performed…
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…
Regarding the Maximal Qubit Violations of n-Locality in Star and Chain Networks
Brian Doolittle, Eric Chitambar
The nonlocal correlations of noisy quantum systems are important for both understanding nature and developing quantum technology. We consider the correlations of star and chain qua…
Inferring Quantum Network Topology using Local Measurements
Daniel T. Chen, Brian Doolittle, Jeffrey M. Larson +2
Statistical correlations that can be generated across the nodes in a quantum network depend crucially on its topology. However, this topological information might not be known a pr…
Variational Quantum Optimization of Nonlocality in Noisy Quantum Networks
Brian Doolittle, Tom Bromley, Nathan Killoran +1
The inherent noise and complexity of quantum communication networks leads to challenges in designing quantum network protocols using classical methods. To address this issue, we de…
The Communication Value of a Quantum Channel
Eric Chitambar, Ian George, Brian Doolittle +1
There are various ways to quantify the communication capabilities of a quantum channel. In this work we study the communication value (cv) of channel, which describes the optimal s…
Certifying the Classical Simulation Cost of a Quantum Channel
Brian Doolittle, Eric Chitambar
A fundamental objective in quantum information science is to determine the cost in classical resources of simulating a particular quantum system. The classical simulation cost is q…
