Abstract Doping enhances the optical properties of high‐band gap zinc oxide nanoparticles (ZnO NPs), essential for their photocatalytic activity. We used the combustion approach to synthesize cobalt‐doped ZnO heterostructure (CDZO). By creating a

Quantum resource theories provide a mathematical framework for quantifying the advantage given by quantum phenomena in various tasks. The generalized robustness is one such quantifier, and enjoys an operational interpretation in the setting of channe

We propose a two step strategy for estimating one-dimensional dynamical parameters of a quantum Markov chain, which involves quantum post-processing the output using a coherent quantum absorber and a "pattern counting'' estimator computed as a simple

We study the statistics of first passage times (FPTs) of trajectory observables in both classical and quantum Markov processes. We consider specifically the FPTs of counting observables, that is, the times to reach a certain threshold of a trajectory

Introduction. Pulmonary thromboembolism (PTE) represents a medical emergency and is the third most common cause of mortality after myocardial infarction and stroke. The purpose of this study was to describe the characteristics and management of patie

We revisit the problem of estimating an unknown parameter of a pure quantum state, and investigate `null-measurement' strategies in which the experimenter aims to measure in a basis that contains a vector close to the true system state. Such strategi

Given the terms of the socia-media revolution that we pass, the goal of the paper is to identify the main types of social media platforms that contribute to increasing the efficiency in the online environment, where we work now. Starting from their c

The main objective of a financial manager is to use the funds of the company within its managerial authority, so that at long-term the firm obtains the investments yield at least as high as that which could be achieved through alternative investmen

Thermodynamic uncertainty relations (TURs) are general lower bounds on the size of fluctutations of dynamical observables. They have important consequences, one being that the precision of estimation of a current is limited by the amount of entropy p

We derive new concentration bounds for time averages of measurement outcomes in quantum Markov processes. This generalizes well-known bounds for classical Markov chains which provide constraints on finite time fluctuations of time-additive quantities
