Thus, we put forward a path to experimentally access the control and detection of a topological quantum phase transition via the Rényi entropy, which can be measured by standard low noise linear amplification techniques in superconducting circuits. Assume that an MxN-sized image can be denoted in L gray levels. Renyi’s entropy method was used to determine the optimal thresholding values of an image. Recently, Savaré-Toscani proved that the Rényi entropy power of general probability densities solving the p-nonlinear heat equation in Rn is a concave function of time under certain conditions of three parameters n,p, which extends Costa’s concavity inequality for Shannon’s entropy power to the Rényi entropy power. Consequently, we show a method to recover the bipartite entanglement of the system from a cavity observable. Uncovering causal interdependencies from observational data is one of the great challenges of a nonlinear time series analysis. The optimal thresholding values were found by optimizing an appropriate criterion function obtained from gray-level distribution and other image properties. ![]() The term and the concept are used in diverse fields, from classical thermodynamics, where it was first recognized, to the microscopic description of nature in statistical physics, and. Even though both display singularities at the topological phase transition points, remarkably only the Rényi entropy can be analytically connected to the measurable Fano factor. Entropy is a scientific concept, as well as a measurable physical property, that is most commonly associated with a state of disorder, randomness, or uncertainty. As a function of the interval size, we expect a Page curve in the entropy. Obtain the level 5 discrete wavelet transform of the signal using the 'db4' wavelet. We study two bipartite entanglement measures, the von Neumann and Rényi entanglement entropies, between light and matter subsystems. In a 1+1 dimensional QFT on a circle, we consider the von Neumann entanglement entropy of an interval for typical pure states. Obtain the Renyi entropy estimates for the tunable Q-factor transform. Moreover, based on density matrix renormalization group numerical calculations, endorsed by an analytical Gaussian approximation for the cavity state, we propose a direct link between those observables and quantum entropy singularities. We show that the topological phase transition for a Kitaev chain embedded in a cavity can be identified by measuring experimentally accessible photon observables such as the Fano factor and the cavity quadrature amplitudes. From their conception to present times, different concepts and definitions of entropy take key roles in a variety of areas from thermodynamics to information science, and they can be applied to both classical and quantum systems. ![]()
