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…
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…
Finite-Key Analysis of Quantum Key Distribution with Characterized Devices Using Entropy Accumulation
Ian George, Jie Lin, Thomas van Himbeeck +2
The Entropy Accumulation Theorem (EAT) was introduced to significantly improve the finite-size rates for device-independent quantum information processing tasks such as device-inde…
Revisiting Pure State Transformations with Zero Communication
Ian George, Eric Chitambar
It is known that general convertibility of bipartite entangled states is not possible to arbitrary error without some classical communication. While some trade-offs between communi…
Cone-Restricted Information Theory
Ian George, Eric Chitambar
The max-relative entropy and the conditional min-entropy it induces have become central to one-shot information theory. Both may be expressed in terms of a conic program over the p…
