Quantum Computation of Partition Function Similarity for Large Language Models

Published Feb 10, 2026• 0 citations
Publisher

Abstract

Large Language Models (LLMs) demand significant computational resources, motivating the exploration of quantum computing to accelerate their analysis. This paper introduces a framework for analyzing LLM embedding spaces using partition functions, drawing an analogy to statistical mechanics. We propose a partition function-based similarity measure and present an experimental evaluation of its implementation on the ibm boston quantum computer, achieving a relative error of approximately 7% compared to classical computation. Results suggest partition functions effectively characterize the statistical properties of embedding vectors, offering a complementary perspective to cosine similarity. This work contributes to quantum natural language processing (QNLP), advancing LLM analysis and semantic representation, with potential implications for reducing the energy footprint and democratizing access to these powerful AI technologies.

Quantum LLMs Using Quantum Computing to Analyze and Process Semantic Information

Timo Aukusti Laine

We present a quantum computing approach to analyzing Large Language Model (LLM) embeddings, leveraging complex-valued representations and modeling semantic relationships using quantum mechanical principles. By establishing a direct mapping between LLM semantic spaces and quantum circuits, we demonstrate the feasibility of estimating semantic similarity using quantum hardware. One of the key results is the experimental calculation of cosine similarity between Google Sentence Transformer embeddings using a real quantum computer, providing a tangible demonstration of a quantum approach to semantic analysis. This work reveals a connection between LLMs and quantum mechanics, suggesting that these principles can offer new perspectives on semantic representation and processing, and paving the way for future development of quantum algorithms for natural language processing.

Quantum-Aware Large Language Models: Taxonomy, Architectures, and Future Applications

Reyhan Dede

The convergence of quantum computing and large language models (LLMs) represents a major milestone in computational intelligence, introducing novel paradigms for information processing, complexity modeling, and scientific advancement. This survey provides a comprehensive overview of the emerging interdisciplinary field that integrates quantum mechanics with natural language processing. We begin by presenting the foundational principles of quantum computing and LLMs, then examine their integration through automated quantum code generation, hybrid transformer architectures, and quantum natural language processing (QNLP) frameworks. State-of-the-art models, such as quantum-augmented attention mechanisms and circuit embedding strategies, are evaluated across domain-specific datasets and benchmarks. We also investigate the role of LLMs as quantum research assistants, educational tools, and simulation agents, particularly in resource-constrained environments. Furthermore, the survey explores challenges related to scalability, interpretability, and quantum data encoding, and outlines future research directions-especially the vision for fully quantum-native LLMs. Our goal is to guide researchers through the current landscape and to encourage continued exploration at the intersection of quantum technologies and advanced language models.

Semantic Wave Functions: Exploring Meaning in Large Language Models through Quantum Formalism

Financial Physics Lab, Finland, Timo Aukusti Laine

Large Language Models (LLMs) encode semantic relationships in high-dimensional vector embeddings. This paper explores the analogy between LLM embedding spaces and quantum mechanics, positing that LLMs operate within a quantized semantic space where words and phrases behave as quantum states. To capture nuanced semantic interference effects, we extend the standard realvalued embedding space to the complex domain, drawing parallels to the double-slit experiment. We introduce a ”semantic wave function” to formalize this quantum-derived representation and utilize potential landscapes, such as the double-well potential, to model semantic ambiguity. Furthermore, we propose a complex-valued similarity measure that incorporates both magnitude and phase information, enabling a more sensitive comparison of semantic representations. We develop a path integral formalism, based on a nonlinear Schro¨dinger equation with a gauge field and Mexican hat potential, to model the dynamic evolution of LLM behavior. This interdisciplinary approach offers a new theoretical framework for understanding and potentially manipulating LLMs, with the goal of advancing both artificial and natural language understanding

Quantum Algorithms for Large Language Models on Noisy Intermediate-Scale Quantum Computers

Timo Aukusti Laine

We present a systematic methodology for developing and validating quantum algorithms for Large Language Models (LLMs). This methodology includes partition function-based transformations to map LLM embedding similarity values to a range suitable for quantum computation, and the design of a shallow-circuit quantum algorithm for estimating this transformed similarity measure on nearterm quantum computers. We rigorously evaluate our approach through quantum simulations and experiments on real quantum hardware, demonstrating the feasibility of using quantum computing for LLM embedding analysis. Our results highlight the potential for quantum-inspired techniques in LLM tasks and demonstrate practical strategies for achieving reliable results on noisy quantum hardware.

Finland Financial Physics Lab, Timo Aukusti Laine

In the previous article, we presented a quantum-inspired framework for modeling semantic representation and processing in Large Language Models (LLMs), drawing upon mathematical tools and conceptual analogies from quantum mechanics to offer a new perspective on these complex systems. In this paper, we clarify the core assumptions of this model, providing a detailed exposition of six key principles that govern semantic representation, interaction, and dynamics within LLMs. The goal is to justify that a quantum-inspired framework is a valid approach to studying semantic spaces. This framework offers valuable insights into their information processing and response generation, and we further discuss the potential of leveraging quantum computing to develop significantly more powerful and efficient LLMs based on these principles.
