On The Reliability Function of Discrete Memoryless Multiple-Access Channel with Feedback
Mohsen Heidari, Achilleas Anastasopoulos, S. Sandeep Pradhan
The reliability function of a channel is the maximum achievable exponential rate of decay of the error probability as a function of the transmission rate. In this work, we derive b…
Quantum soft-covering lemma with applications to rate-distortion coding, resolvability and identification via quantum channels
Touheed Anwar Atif, S. Sandeep Pradhan, Andreas Winter
We propose a quantum soft-covering problem for a given general quantum channel and one of its output states, which consists in finding the minimum rank of an input state needed to…
Multi-Party Quantum Purity Distillation with Bounded Classical Communication
Touheed Anwar Atif, S. Sandeep Pradhan
We consider the task of distilling local purity from a noisy quantum state , wherein we provide a protocol for three parties, Alice, Bob and Charlie, to distill local puri…
Lattices from Linear Codes: Source and Channel Networks
Farhad Shirani, S. Sandeep Pradhan
In this paper, we consider the information-theoretic characterization of the set of achievable rates and distortions in a broad class of multiterminal communication scenarios with…
Unified approach for computing sum of sources over CQ-MAC
Mohammad Aamir Sohail, Touheed Anwar Atif, S. Sandeep Pradhan +1
We consider the task of communicating a generic bivariate function of two classical sources over a Classical-Quantum Multiple Access Channel (CQ-MAC). The two sources are observed…
Upper Bounds on the Feedback Error Exponent of Channels With States and Memory
Mohsen Heidari, Achilleas Anastasopoulos, S. Sandeep Pradhan
As a class of state-dependent channels, Markov channels have been long studied in information theory for characterizing the feedback capacity and error exponent. This paper studies…
