Achieving Heisenberg scaling with maximally entangled states: An analytic upper bound for the attainable root-mean-square error [PDF]

open access: yesPhysical Review A, 2020
In this paper we explore the possibility of performing Heisenberg limited quantum metrology of a phase, without any prior, by employing only maximally entangled states. Starting from the estimator introduced by Higgins et al. in New J. Phys.

Neutron optical test of completeness of quantum root-mean-square errors [PDF]

open access: yesnpj Quantum Information, 2021
AbstractWhile in classical mechanics the mean error of a measurement is solely caused by the measuring process (or device), in quantum mechanics the operator-based nature of quantum measurements has to be considered in the error measure as well. One of the major problems in quantum physics has been to generalize the classical root-mean-square error to ...

Evaluation of SSM-Wheat Model in Simulating the Growth and Development of Wheat (Triticum aestivum L.) Cultivars in Different Planting Densities [PDF]

open access: yesبوم شناسی کشاورزی
IntroductionWheat (Triticum aestivum L.) is one of the most important and widely consumed crops in the world. Changing the density towards an optimal density can alter the ratio of soil evaporation to plant transpiration in such a way that water use ...

Iterative bicluster-based Bayesian principal component analysis and least squares for missing-value imputation in microarray and RNA-sequencing data

open access: yesMathematical Biosciences and Engineering, 2022
Microarray and RNA-sequencing (RNA-seq) techniques each produce gene expression data that can be expressed as a matrix that often contains missing values.

Disturbance impulse effects on large umbrella space reflector dynamics [PDF]

open access: yes, 2016
Large umbrella space antennas are essential for communication, monitoring and observation of Earth and space objects. Despite investigations devoted to space antenna dynamics, the disturbance impulse shape effect on the root mean square error of ...

Quantum Metrology with Indefinite Causal Order [PDF]

open access: yes, 2020
We address the study of quantum metrology enhanced by indefinite causal order, demonstrating a quadratic advantage in the estimation of the product of two average displacements in a continuous variable system.
