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

On diagonal quantum channels [PDF]
Reports on Mathematical Physics, 2021 In this paper we study diagonal quantum channels and their structure by proving some results and giving most applicable instances of them. Firstly, it is shown that action of every diagonal quantum channel on pure state from computational basis is a convex combination of pure states determined by some transition probabilities.

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

Incompatibility of quantum channels [PDF]
Journal of Physics A: Mathematical and Theoretical, 2017 Two quantum channels are called compatible if they can be obtained as marginals from a single broadcasting channel; otherwise they are incompatible. We derive a characterization of the compatibility relation in terms of concatenation and conjugation, and we show that all pairs of sufficiently noisy quantum channels are compatible.

An Invitation to Quantum Channels [PDF]
Quanta, 2018 Open quantum systems have become an active area of research, owing to its potential applications in many different fields ranging from computation to biology. Here, we review the formalism of dynamical maps used to represent the time evolution of open quantum systems and discuss the various representations and properties of the same, with many examples.

Dilation, Discrimination and Uhlmann's Theorem of Link Products of Quantum Channels [PDF]
Chin. Phys. B 33, 030304 (2024), 2023 The study of quantum channels is the most fundamental theoretical problem in quantum information and quantum communication theory. The link product theory of quantum channels is an important tool for studying quantum networks. In this paper, we establish the Stinespring dilation theorem of the link product of quantum channels in two different ways ...

Relating Entropies of Quantum Channels [PDF]
Entropy, 2021 In this work, we study two different approaches to defining the entropy of a quantum channel. One of these is based on the von Neumann entropy of the corresponding Choi–Jamiołkowski state. The second one is based on the relative entropy of the output of the extended channel relative to the output of the extended completely depolarizing channel.
