Quantum computation offers new directions in computer science that go beyond classical systems' state-of-the-art abilities. The combination of quantum technologies with Large Language Models (LLMs) provides promising avenues for the creation of more efficient and powerful NLP architectures. In this research, we examine quantum-enhanced transformers and further develop the Self-Attention Sequential Quantum Transformer Channel (SASQuatch) framework to enhance inference time and perplexity. The models proposed are tested on sentence completion tasks and compared against a baseline transformer, showing significant gains in efficiency and predictive power. We further compare the method with other optimization methods, such as the Quantum Approximate Optimization Algorithm (QAOA), thus highlighting the necessity of further investigation of hybrid quantum architectures in improving the performance of large-scale language models.

Significant computational challenges exist in the training of large language models (LLMs), specifically for the efficient convergence. This paper discusses a hybrid quantum-classical framework designed to address these challenges. With the integration of quantum computing principles, like the superposition, entanglement, and tunneling, into the classical deep learning methods, an approach is studied to accelerate convergence, enhance optimization efficiency, and improve model generalization. A quantum feature mapping is used to project classical data into high-dimensional Hilbert spaces, enhancing data representation and revealing more complex feature patterns in the data. The quantum-assisted optimization algorithms, like Quantum Approximate Optimization Algorithm (QAOA) and Variational Quantum Eigensolver (VQE), can efficiently find optimal solutions within complex, non-convex loss landscapes and mitigate the issues of local minima encountered by classical methods. Furthermore, the quantum-accelerated matrix operations, with the use of Harrow-Hassidim-Lloyd (HHL) algorithm or Quantum Fourier Transform (QFT) etc., can provide computational speed-ups for the LLM training. Quantum measurement introduces inherent randomness, similar to the dropout in deep neural networks, where certain neurons are randomly deactivated during training. In the noisy intermediate-scale quantum (NISQ) era, our quantum-classical framework and conceptual analyses demonstrate the feasibility and potential advantages. This work lays the foundation for future research in this area.
This paper presents a comprehensive evaluation of quantum text generation models against traditional Transformer/MLP architectures, addressing the growing interest in quantum computing applications for natural language processing. We conduct systematic experiments comparing five distinct models: Transformer (baseline), Quantum Kernel Self-Attention Network (QKSAN), Quantum RWKV (QRWKV), and Quantum Attention Sequence Architecture (QASA) across five diverse datasets including simple sentences, short stories, quantum phrases, haiku poetry, and proverbs. Our evaluation employs multiple metrics including perplexity, BLEU scores, vocabulary diversity, repetition rates, and fluency measures to assess different aspects of text generation quality. The experimental results reveal that while traditional Transformer models maintain overall superiority with the lowest average perplexity (1.21) and highest BLEU-1 score (0.2895), quantum-inspired models demonstrate competitive performance in specific scenarios. Notably, QKSAN achieves a competitive BLEU-1 score of 0.2800 while maintaining zero repetition rates, and QRWKV demonstrates perfect vocabulary diversity (Distinct-1 = 1.000) in certain tasks.
Large Language Models (LLMs) such as GPT and LLaMA have transformed artificial intelligence, but their rapid growth has brought major challenges in computation, energy use, and scalability. Quantum computing (QC) offers a fundamentally different way to process information, with the potential to accelerate key operations in training, inference, optimization, and representation learning. This survey provides a structured and comprehensive review of how QC can support the future development of LLMs. It examines quantum algorithms, hybrid quantum-classical methods, quantum neural networks, quantum embeddings, and security applications. It also evaluates their feasibility in both the current noisy intermediate-scale quantum (NISQ) era and the future fault-tolerant era. The survey highlights current progress, identifies major technical barriers, and outlines practical research directions needed to build scalable, efficient, and secure quantum-enhanced language models.
Quantum computing with its capacity to compute multiple possibilities at once, and perform some kinds of calculations almost instantly is one leading edge. The integration of QCs and DL undoubtedly represent one such transformative means for improving Natural Language Processing (NLP). By combining the two, this uses quantum principles of superposition and entanglement to make computation faster regarding human language comprehension limitations in classical computing. Deep learning models, specifically neural networks have already made significant improvements over NLP tasks like language translations, sentiment analysis and text generation. Nevertheless, these models also face scalability and computational efficiency issues with huge volumes of data. Quantum computing offers a solution to all this by reducing the time exponentially that it takes to fetch large amounts of language data and running deep learning algorithms. This paper investigates the opportunities that integrating quantum computing and deep learning into NLP practices might unlock. We drafted the fundamentals of quantum computing and why it is a need over classical computing, where we discussed on how quantum beneficial for data processing & optimization of an algorithm. We then explore applications of quantum enhanced deep learning for NLP, with a focus on the impact that training and inference can have on model performance. We demonstrate the utility of this integration by integrating our four SQDs to showcase improvements on diverse NLP tasks through a series of experiments and case studies. We also demonstrate that hybrid quantum-classical approaches allow the combination of traditional ML and quantum-enhanced models, achieving state-of-the-art performance with respect to effectiveness, scalability and precision
The success of the self-attention mechanism in classical machine learning models has inspired the development of quantum analogs aimed at reducing the computational overhead. Self-attention integrates learnable query and key matrices to calculate attention scores between all pairs of tokens in a sequence. These scores are then multiplied by a learnable value matrix to obtain the output self-attention matrix, enabling the model to effectively capture long-range dependencies within the input sequence. Here, we propose a hybrid quantum-classical self-attention mechanism as part of a transformer decoder, the architecture underlying large language models (LLMs). To demonstrate its utility in chemistry, we train this model on the QM9 dataset for conditional generation, using SMILES strings as input, each labeled with a set of physicochemical properties that serve as conditions during inference. Our theoretical analysis shows that the time complexity of the query-key dot product is reduced from O ( n 2 d ) in a classical model to O ( n 2 log d ) in our quantum model, where n and d represent the sequence length and the embedding dimension, respectively. We perform simulations using NVIDIA’s CUDA-Q platform, which is designed for efficient GPU scalability. This work provides a promising avenue for quantum-enhanced natural language processing (NLP).
