Probabilistic Teleportation of Arbitrary Two-Qubit Quantum State via Non-Symmetric Quantum Channel [PDF]
Entropy, 2018 Quantum teleportation has significant meaning in quantum information. In particular, entangled states can also be used for perfectly teleporting the quantum state with some probability. This is more practical and efficient in practice.

Quantum Information Transmission Over a Partially Degradable Channel [PDF]
IEEE Access, 2014 We investigate a quantum coding for quantum communication over a partially degradable (PD) quantum channel. For a PD channel, the degraded environment state can be expressed from the channel output state up to a degrading map.

Quantumness and Dequantumness Power of Quantum Channels
Entropy, 2022 Focusing on the dynamics of quantumness in ensembles, we propose a framework to qualitatively and quantitatively characterize quantum channels from the perspective of the amount of quantumness in ensembles that a quantum channel can induce or reduce ...

Order-Stability in Complex Biological, Social, and AI-Systems from Quantum Information Theory
Entropy, 2021 This paper is our attempt, on the basis of physical theory, to bring more clarification on the question “What is life?” formulated in the well-known book of Schrödinger in 1944.

Information transmission with continuous variable quantum erasure channels [PDF]
Quantum, 2023 Quantum capacity, as the key figure of merit for a given quantum channel, upper bounds the channel's ability in transmitting quantum information. Identifying different types of channels, evaluating the corresponding quantum capacity, and finding the ...

Atmospheric implementation of superdense coding quantum algorithm
Physics of Complex Systems, 2022 We consider the properties of a quantum communication channel in open space using the superdense coding algorithm as an example. We studied the theoretical model of the installation that implements this algorithm, and identified the main factors ...

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).
