Unfortunately, some errors were detected after publication of the article referred to in the title. This errata corrects errors in the proofs of Lemma 5 on page 23 and Proposition 1 on page 26 of the article. The authors also noticed a weaker condition for Lemma 1 on page 19 to hold. The corrections and improvements do not impact the main results a...

Machine learning has achieved success in many areas because of its powerful fitting ability, so we hope it can help us to solve some significant physical quantitative problems, such as quantum correlation. In this research, we will use neural networks to predict the value of quantum discord. Quantum discord is a measure of quantum correlation which...

This study presents a bidirectional quantum teleportation of two quantum states with an arbitrary number of qubits, n, for the first time. This protocol utilizes a particular state with 4n qubits as a quantum channel. The required operators include CNOT, Paulis and single-qubit measurements. In this paper, we also present a comprehensive noise anal...

Finding four six-dimensional mutually unbiased bases (MUBs) is a long-standing open problem in quantum information. By assuming that they exist and contain the identity matrix, we investigate whether the remaining three MUBs have an H2\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} ...

In this paper, we propose a quantum–classical hybrid filtering scheme used for denoising of a classical noisy image field. This includes an iterative procedure of transforming pairs of classical image and noise fields into quantum states using standard classical–quantum conversion and then posing the problem of constructing an optimal unitary opera...

We study a quantum-state transfer protocol between two end spins of a disordered spin-1/2 chain. We particularly evaluate the performance of the channel when it is subjected to short-range correlated on-site fluctuations. This is implemented by generating a random distribution of dimer-like defects across the chain featuring a given on-site potenti...

Proposing an optomechanical cavity modulated periodically, we have studied the modulation synchronization of the mechanical modes of mirrors. A periodic modulation has been applied to one of the mirrors, where the second mirror has the capability of oscillation with no modulation on that. As a result of having the periodic modulation, we have found...

The quantification of coherence is central in quantum information theory and far from being fully understood, particularly for multipartite quantum states. In this work, we first propose the coherence eigenvalue for multipartite pure quantum states and then define the coherence measure for a given multipartite pure or mixed state based on it. It is...
Super-quantum discord is an extension of the quantum discord concept where weak measurements are made instead of projective measurements. We study the temperature behavior of the super-quantum discord for two real magnetic materials. We extract information about super-quantum discord from the magnetic susceptibility data for iron nitrosyl complexes...

In this paper, the new quantum image representation model OQIM is proposed to provide a representation for digital images on quantum computers in the form of a normalized state. The newly proposed quantum image representation OQIM uses the basis state of a qubit sequence to store the ascending order of each pixel according to their gray values’ mag...
