Variance-based uncertainty relations for incompatible observables

We formulate uncertainty relations for arbitrary finite number of incompatible observables. Based on the sum of variances of the observables, both Heisenberg-type and Schrödinger-type uncertainty relations are provided. These new lower bounds are stronger in most of the cases than the ones derived from some existing inequalities. Detailed examples are presented. [email protected] sophyc21@163...

Variance-based uncertainty relation for incompatible observers

Based on mixedness definition as ( ), we obtain a new variance-based uncertainty equality along with an inequality for Hermitian operators of a single-qubit system. The obtained uncertainty equality can be used as a measure of the system mixedness. A qubit system with feedback control is also exploited to demonstrate the new uncertainty.

Turkish - Iranian Relations: Prospects and Uncertainty

Iran and Turkey are two key regional actors that separately play a role in multiple geographies in terms of both geographical weight and tenets of identity. Geographically speaking, these two countries are simultaneously influential in political-security issues in different areas such as the Fertile Crescent. When it comes to identity, by making a link between their principles and values to reg...

Parameter uncertainty effects on variance-based sensitivity analysis

In the past several years there has been considerable commercial and academic interest in methods for variance-based sensitivity analysis. The industrial focus is motivated by the importance of attributing variance contributions to input factors. A more complete understanding of these relationships enables companies to achieve goals related to quality, safety and asset utilization. In a number ...
