A hypothesis testing approach for communication over entanglement assisted compound quantum channel
Anurag Anshu, Rahul Jain, Naqueeb Ahmad Warsi
We study the problem of communication over a compound quantum channel in the presence of entanglement. Classically such channels are modeled as a collection of conditional probabil…
One-Shot Private Classical Capacity of Quantum Wiretap Channel: Based on one-shot quantum covering lemma
Jaikumar Radhakrishnan, Pranab Sen, Naqueeb Ahmad Warsi
In this work we study the problem of communication over the quantum wiretap channel. For this channel there are three parties Alice (sender), Bob (legitimate receiver) and Eve (eav…
A generalized quantum Slepian-Wolf
Anurag Anshu, Rahul Jain, Naqueeb Ahmad Warsi
In this work we consider a quantum generalization of the task considered by Slepian and Wolf [1973] regarding distributed source compression. In our task Alice, Bob, Charlie and Re…
Convex-split and hypothesis testing approach to one-shot quantum measurement compression and randomness extraction
Anurag Anshu, Rahul Jain, Naqueeb Ahmad Warsi
We consider the problem of quantum measurement compression with side information in the one-shot setting with shared randomness. In this problem, Alice shares a pure state with Ref…
One shot entanglement assisted classical and quantum communication over noisy quantum channels: A hypothesis testing and convex split approach
Anurag Anshu, Rahul Jain, Naqueeb Ahmad Warsi
Capacity of a quantum channel characterizes the limits of reliable communication through a noisy quantum channel. This fundamental information theoretic question is very well studi…
