Non-Classical Information Entropy: A Statistical Physics Perspective

Published Sep 3, 2026• 0 citations

Abstract

This paper introduces a novel definition of non-classical information entropy, rooted in the principles of statistical physics, particularly quantum mechanics. The core premise is that traditional information entropy, derived from classical probability theory, is insufficient to capture the essence of information within non-classical systems exhibiting phenomena such as superposition and entanglement. We propose a definition based on the concept of accessible states and their associated probabilities, extending the notion of entropy beyond the realm of purely deterministic systems. The paper details the mathematical formulation of this non-classical information entropy, denoted as *Hnc*, and presents a method for its calculation. The method relies on identifying the set of accessible states for a given system and then applying a generalized form of Shannon's entropy formula, modified to account for the inherent uncertainties associated with quantum mechanics. The resulting *Hnc* provides a quantitative measure of the information content within non-classical systems, offering a potential framework for studying information processing and dynamics in quantum environments. The key contribution lies in bridging the gap between information theory and non-classical statistical physics, offering a new lens through which to understand information in quantum systems.

Quantum Information Entropy: A Generalized Definition

Jincheng Zhang

This paper introduces a generalized definition of quantum information entropy, aiming to provide a more comprehensive framework for quantifying information in complex quantum systems. The core of this work lies in extending the conventional concept of entropy, traditionally applied to classical information, to the realm of quantum mechanics. We explore various types of quantum entropy, including von Neumann entropy, relative entropy, and a newly proposed generalized entropy, denoted as *Eg*. The definition of *Eg* is based on a novel approach that considers the entanglement structure and correlations within quantum states. We establish relationships between these different entropy measures, demonstrating their interconnectedness within the broader context of quantum information theory. The paper further outlines a mathematical formalism for calculating *Eg*, providing a tool for analyzing and characterizing quantum information. Our generalized entropy provides a more flexible and potentially more accurate measure of quantum information, particularly in scenarios involving complex quantum correlations and multi-partite quantum systems. ---

Non-Classical Correlation Entropy as a Measure of Quantum State Measurement Trustworthiness

Jincheng Zhang

This paper introduces a novel method for assessing the trustworthiness of quantum state measurement results based on non-classical correlation entropy. The core idea revolves around quantifying the correlation within quantum states using this entropy measure. By analyzing the associated entropy, we can evaluate the reliability of measurement outcomes and subsequently propose corrective and optimization strategies. Traditional approaches to quantum measurement uncertainty often rely on probabilistic interpretations and lack a direct quantification of the inherent correlations within the quantum state itself. This work aims to bridge this gap by providing a framework for assessing trustworthiness rooted in the fundamental properties of quantum entanglement and correlation. We present a detailed mathematical formulation, focusing on the calculation of the non-classical correlation entropy and its application to evaluating measurement confidence. The methodology offers a potentially valuable tool for guiding decision-making in quantum information processing, particularly in scenarios where the precise characterization of the quantum state is challenging. Further investigation into the sensitivity of the method to various noise sources and its scalability for complex quantum systems is warranted. ---

Jincheng Zhang

This paper introduces a novel approach to information theory, leveraging quantum entanglement entropy as a fundamental measure of information. We propose that entanglement entropy can effectively quantify the efficiency of information transmission and provides a theoretical foundation that surpasses the limitations of classical information theory. The core of this work lies in the integration of entanglement entropy with Shannon entropy, establishing a new framework for analyzing information transfer. We explore scenarios where classical information theory struggles to adequately describe the limits of communication due to quantum mechanical effects, specifically entanglement.

Quantum Entanglement Entropy Compression

Jincheng Zhang

This paper proposes a novel approach to entropy compression leveraging the unique properties of quantum entanglement. We demonstrate that, through the careful design of entangled states, it is possible to achieve compression rates exceeding those predicted by the classical Shannon limit. The core mechanism relies on encoding information within the quantum state distribution of an entangled state and exploiting the non-classical correlations inherent in entanglement for efficient probability distribution compression. Unlike traditional entropy compression methods which rely on statistical properties of classical information, our approach directly utilizes the correlations provided by entanglement, offering a fundamentally different strategy. We formulate the theoretical framework, outlining the key mathematical concepts and presenting a detailed analysis of the compression process. The central argument is that entanglement allows for a more effective representation of information than is possible with purely classical distributions, leading to a demonstrable advantage in compression. This work challenges the conventional understanding of entropy and compression, suggesting a new paradigm where quantum phenomena can be harnessed to surpass classical limitations. The presented model incorporates the concepts of entropy, entanglement entropy, and quantum state tomography to provide a comprehensive framework for this novel compression technique. The theoretical foundation is built upon the principles of quantum information theory, with a particular focus on the role of entanglement in information processing and storage. ---

Quantum Causal Entropy

Jincheng Zhang

This paper introduces Quantum Causal Entropy (QCE), a novel framework that extends the concept of entropy to incorporate causal relationships within quantum systems. Traditional entropy measures uncertainty in a system, quantified by the Shannon entropy formula: [S] = - Σ p(s) * log(p(s)), where p(s) represents the probability of a state 's'. QCE posits that causal relationships also possess an entropy component, denoted as [Sc], which describes the degree of uncertainty regarding the *consequences* of a quantum event, reflecting the inherent unpredictability of their cause-effect dynamics. The methodology involves conducting quantum causal experiments, primarily through carefully designed quantum interference experiments, to empirically determine the causal entropy of specific quantum processes. This work lays the groundwork for establishing a fundamental theory of quantum causal physics, potentially unlocking new insights into the nature of reality and possessing significant implications for future technological advancements. The core contribution of this research lies in redefining entropy to encompass not just uncertainty but also the inherent causal structure of quantum phenomena.
