Communication, Dynamical Resource Theory, and Thermodynamics

open access: yesPRX Quantum, 2021
Recently, new insights have been obtained by jointly studying communication and resource theory. This interplay consequently serves as a potential platform for interdisciplinary studies.

Additive Classical Capacity of Quantum Channels Assisted by Noisy Entanglement. [PDF]

open access: yesPhysical Review Letters, 2016
We give a capacity formula for the classical information transmission over a noisy quantum channel, with separable encoding by the sender and limited resources provided by the receiver's preshared ancilla.

Symplectic capacities of classical domains [PDF]

open access: yesInternational Mathematical Forum, 2007
In this note we calculate Gromov symplectic width and Hofer- Zehnder symplectic capacity for the classical domains.

Partial quantisation scheme for optimising the performance of hopfield network

open access: yesFrontiers in Physics, 2022
The ideal Hopfield network would be able to remember information and recover the missing information based on what has been remembered. It is expected to have applications in areas such as associative memory, pattern recognition, optimisation computation,

Strong Converse for the Feedback-Assisted Classical Capacity of Entanglement-Breaking Channels [PDF]

open access: yesProblems of Information Transmission, 2015
Quantum entanglement can be used in a communication scheme to establish a correlation between successive channel inputs that is impossible by classical means.

Probabilistic Monads, Domains and Classical Information [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2012
Shannon's classical information theory uses probability theory to analyze channels as mechanisms for information flow. In this paper, we generalize results of Martin, Allwein and Moskowitz for binary channels to show how some more modern tools ...

Quantum-locked key distribution at nearly the classical capacity rate. [PDF]

open access: yesPhysical Review Letters, 2014
Quantum data locking is a protocol that allows for a small secret key to (un)lock an exponentially larger amount of information, hence yielding the strongest violation of the classical one-time pad encryption in the quantum setting.

Contextuality in entanglement-assisted one-shot classical communication [PDF]

open access: yesQuantum, 2022
We consider the problem of entanglement-assisted one-shot classical communication. In the zero-error regime, entanglement can increase the one-shot zero-error capacity of a family of classical channels following the strategy of Cubitt et al., Phys.

Entanglement-assisted capacity regions and protocol designs for quantum multiple-access channels

open access: yesnpj Quantum Information, 2021
We solve the entanglement-assisted (EA) classical capacity region of quantum multiple-access channels (MACs) with an arbitrary number of senders. As an example, we consider the bosonic thermal-loss MAC and solve the one-shot capacity region enabled by an

Classical capacity of Gaussian communication under a single noisy channel [PDF]

open access: yes, 2015
A long-standing problem on the classical capacity of bosonic Gaussian channels has recently been resolved by proving the minimum output entropy conjecture.
