Increasing the Protocol Gain of Quantum Cryptography [PDF]

open access: yesEngineering and Technology Journal, 2013
Quantum cryptography is a technique to distribute a sequence of truly random and unconditionally secure bits over a secure communication by applying the phenomena of quantum physics.

Selfcomplementary Quantum Channels [PDF]

open access: yesOpen Systems & Information Dynamics, 2016
Selfcomplementary quantum channels are characterized by such an interaction between the principal quantum system and the environment that leads to the same output states of both interacting systems. These maps can describe approximate quantum copy machines, as perfect copying of an unknown quantum state is not possible due to the celebrated no-cloning

Quantum Channel Simulation and the Channel's Smooth Max-Information [PDF]

open access: yesInternational Symposium on Information Theory, 2018
We study the general framework of quantum channel simulation, that is, the ability of a quantum channel to simulate another one using different classes of codes. Our main results are as follows.

A Survey on Quantum Channel Capacities [PDF]

open access: yesIEEE Communications Surveys and Tutorials, 2018
Quantum information processing exploits the quantum nature of information. It offers fundamentally new solutions in the field of computer science and extends the possibilities to a level that cannot be imagined in classical communication systems.

QUANTUM TELEPORTATION OF ENTANGLED STATES VIA GENERALIZED PHOTON-ADDED PAIR COHERENT STATE

open access: yesTạp chí Khoa học Đại học Đà Lạt, 2023
In this paper, we study the quantum teleportation of an unknown atomic state based on the two-photon Jaynes-Cummings model, consisting of an effective two-level atom with a two-mode field in the generalized photon-added pair coherent state (GPAPCS).

Coherifying quantum channels [PDF]

open access: yesNew Journal of Physics, 2018
Is it always possible to explain random stochastic transitions between states of a finite-dimensional system as arising from the deterministic quantum evolution of the system? If not, then what is the minimal amount of randomness required by quantum theory to explain a given stochastic process?

Geometric Rényi Divergence and its Applications in Quantum Channel Capacities [PDF]

open access: yesCommunications in Mathematical Physics, 2019
Having a distance measure between quantum states satisfying the right properties is of fundamental importance in all areas of quantum information. In this work, we present a systematic study of the geometric Rényi divergence (GRD), also known as the ...
