Quantum Shannon theory made robust: a tale of three protocols for almost i.i.d. sources
Filippo Girardi, Nilanjana Datta, Giacomo De Palma +1
The asymptotic rates of information-theoretic protocols - including error exponents, data-compression rates, and channel capacities - are traditionally derived under the idealised…
Robustness of Entanglement Manipulation for almost i.i.d. sources
Nilanjana Datta
We study the robustness of asymptotic entanglement manipulation for Mazzola--Sutter--Renner (MSR) almost-iid sources, which allow a sublinear number of deviations from tensor-power…
Entropy Concentration and Universal Typicality for Almost i.i.d. Quantum Sources
Nilanjana Datta
We establish two concentration principles for almost i.i.d. quantum sources under the weakly almost i.i.d. condition, the broadest condition in the established hierarchy of almost…
Information storage and transmission under Markovian noise
Satvik Singh, Nilanjana Datta
We study the information transmission capacities of quantum Markov semigroups acting on dimensional quantum systems. We show that, in the limit of $t\…
Tight relations and equivalences between smooth relative entropies
Bartosz Regula, Ludovico Lami, Nilanjana Datta
The precise one-shot characterisation of operational tasks in classical and quantum information theory relies on different forms of smooth entropic quantities. A particularly impor…
Information transmission under Markovian noise
Satvik Singh, Nilanjana Datta
We consider an open quantum system undergoing Markovian dynamics, the latter being modelled by a discrete-time quantum Markov semigroup , resulting from…
Optimal continuity bound for the von Neumann entropy under energy constraints
S. Becker, N. Datta, M. G. Jabbour +1
Using techniques proposed in [Sason, IEEE Trans. Inf. Th. 59, 7118 (2013)] and [Becker, Datta and Jabbour, IEEE Trans. Inf. Th. 69, 4128 (2023)], and based on the results from the…
Continuity bounds for quantum entropies arising from a fundamental entropic inequality
Koenraad Audenaert, Bjarne Bergh, Nilanjana Datta +3
We establish a tight upper bound for the difference in von Neumann entropies between two quantum states, and . This bound is expressed in terms of the von Neumann entrop…
Zero-error communication under discrete-time Markovian dynamics
Satvik Singh, Mizanur Rahaman, Nilanjana Datta
Consider an open quantum system with (discrete-time) Markovian dynamics. Our task is to store information in the system in such a way that it can be retrieved perfectly, even after…
Tightening continuity bounds for entropies and bounds on quantum capacities
Michael G. Jabbour, Nilanjana Datta
Uniform continuity bounds on entropies are generally expressed in terms of a single distance measure between a pair of probability distributions or quantum states, typically, the t…
