Introduction
I'm working on quantum information. Of particular interest are the properties of entropy, especially observational entropy and quantum correlation entropy. If you are interested in observational entropy or other entropies, we might be a good partner. You are welcome to contact me. My email address: zhoux2032@163.com.

This study aims to investigate the distribution of distance-based quantum resources for fermionic fields in curved Schwarzschild spacetime (SST), as well as for bosonic fields in both flat Minkowski and curved SSTs. To achieve this, we will examine the quantum resources between an observer falling into a Schwarzschild black hole (SBH) and their sta...
We obtain analytical expressions for distance-based quantum resources and examine their distribution in the proximity of a Schwarzschild black hole (SBH) within a curved background. For an observer in free fall and their stationary counterpart sharing the Gisin state, the quantum resources are degraded at infinite Hawking temperature. The extent of...
A superposition measure with respect to coarse-grained measurement is presented in this paper. We consider a special kind of mixed states—the generalized n-qubit Werner state as the initial state. We take an appropriate coarse-graining acting on the initial state and find that the observational entropy and the von Neumann entropy are equal for any...
Quantum correlation entropy is used to measure total non-classical correlation of multiple states. It is based on a local coarse-grained measurement. Quantum noisy processes have a theoretically and experimentally important role in quantum information tasks. We study the dynamical behavior of quantum correlation entropy of output state under the ef...
Relations between observational entropy and other measures based on Tsallis-q entropy are presented in this paper. For two-qubit pure states, relations between observational entropy and Tsallis-q entanglement through some monotone function are given. We generalize these relations to the two-qubit mixed state for some range of q. For the case of mix...
Observational entropy is a generalization of Boltzmann entropy to quantum mechanics. Observational entropy based on coarse-grained measurements has a certain relations with other quantum information measures. We study the relations between observational entropy and Rényi information measures and give some examples to explain the rationality of thes...
Observational entropy is a generalization of Boltzmann entropy to quantum mechanics. Observational entropy based on coarse-grained measurements has a certain relations with other quantum information measures. Quantum correlation entropy and quantum discord are both physical quantities used to measure quantum correlation. The former is based on loca...
