Face recognition is one of the most ubiquitous examples of pattern recognition in machine learning, with numerous applications in security, access control, and law enforcement, among many others. Pattern recognition with classical algorithms requires significant computational resources, especially when dealing with high-resolution images in an extensive database. Quantum algorithms have been shown to improve the efficiency and speed of many computational tasks, and as such, they could also potentially improve the complexity of the face recognition process. Here, we propose a quantum machine learning algorithm for pattern recognition based on quantum principal component analysis (QPCA), and quantum independent component analysis (QICA). A novel quantum algorithm for finding dissimilarity in the faces based on the computation of trace and determinant of a matrix (image) is also proposed. The overall complexity of our pattern recognition algorithm is O(Nlog N) -- $N$ is the image dimension. As an input to these pattern recognition algorithms, we consider experimental images obtained from quantum imaging techniques with correlated photons, e.g. "interaction-free" imaging or "ghost" imaging. Interfacing these imaging techniques with our quantum pattern recognition processor provides input images that possess a better signal-to-noise ratio, lower exposures, and higher resolution, thus speeding up the machine learning process further. Our fully quantum pattern recognition system with quantum algorithm and quantum inputs promises a much-improved image acquisition and identification system with potential applications extending beyond face recognition, e.g., in medical imaging for diagnosing sensitive tissues or biology for protein identification.Face recognition is one of the most ubiquitous examples of pattern recognition in machine learning, with numerous applications in security, access control, and law enforcement, among many others.

Quantum-Enhanced Facial Biometrics: A Hybrid Framework with Post-Quantum Security

Satinder Singh, Avnish Thakur, Moin Hasan +1 more

Face recognition systems are widely used for biometric authentication but face two major problems. First, processing high-resolution images and large databases requires extensive computational time. Second, emerging quantum computers threaten to break the encryption methods that protect stored facial templates. Quantum computers will soon be able to decrypt current security systems, putting biometric data at permanent risk since facial features cannot be changed like passwords. This paper presents a solution that uses quantum computing to speed up face recognition while adding quantum-resistant security. It applies quantum principal component analysis (QPCA) and the SWAP test to reduce the computational complexity and implement lattice-based cryptography, which quantum computers cannot break. Experimental evaluation demonstrates a significant overall speedup with improved accuracy. The proposed framework achieves a significant improvement in performance, provides 125-bit security against quantum attacks and compresses the data storage requirements significantly. These results demonstrate that quantum-enhanced face recognition can solve both the speed and security challenges facing current biometric systems, making it practical for real-world deployment as quantum technology advances.Face recognition systems are widely used for biometric authentication but face two major problems.

Quantum Machine Learning Techniques for High-Performance Pattern Recognition

Isha Sethi

Quantum computing has emerged as a radical paradigm of computationally tasks which cannot be achieved through classical systems. Quantum Computer-Assisted Machine Learning (Quantum Machine Learning) The use of quantum mechanics and principles of artificial intelligence, such that the quantum mechanics principles of superposition, entanglement and tunnelling are used to improve pattern recognition. Big data dimensions, exponential growth feature space, optimization bottlenecks will not be effectively handled using currently available machine learning algorithms. It is anticipated that QML will deliver factors-of-four to exponential training and inference gains, especially on high-performance pattern recognition tasks in on-the-edge applications, including image processing, natural language processing, and cybersecurity. This is a review article of quantum machine learning (high-performance pattern recognition). It studies some of the underlying paradigms of quantum support vector machine (QSVMs), quantum k-means clustering, variational quantum circuits (VQCs) and quantum-classical deep learning systems. The benefits of QML are addressed in relation to scalability, generalization, and resilience of high dimensional data space. Such use cases include biomedical imaging, business fraud, and material discovery. The QML does have several opportunities, but is restricted by noisy intermediate-scale quantum (NISQ) machines and error correction costs, and cannot be as easily co-located with classical pipes. Another objective of this paper is to discover the significance of the hybrid quantum-classical models that are the most realistic line of attack today, to the application of quantum techniques. The next line of research is hardware-efficient algorithms, quantum feature maps, and practical benchmarking of QML. The quantum computing-artificial intelligence interface can be the new frontier to highly-performing, scaled-out, and efficient pattern recognition systems in data-focused industries, QML may become the future of computation.Quantum computing has emerged as a radical paradigm of computationally tasks which cannot be achieved through classical systems.

Quantum Eigenfaces: Linear Feature Mapping and Nearest Neighbor Classification with Outlier Detection

Armando Bellante, William Bonvini, Stefano Vanerio +1 more

We propose a quantum machine learning algorithm for data classification, inspired by the seminal computer vision approach of eigenfaces for face recognition. The algorithm enhances nearest neighbor/centroid classifiers with concepts from principal component analysis, enabling the automatic detection of outliers and finding use in anomaly detection domains beyond face recognition. Assuming classical input data, we formalize how to implement the algorithm using a quantum random access memory and state-of-the-art quantum linear algebra, discussing the complexity of performing the classification algorithm on a fault-tolerant quantum device. The asymptotic time complexity analysis shows that the quantum classification algorithm can be more efficient than its classical counterpart. We showcase an application of this algorithm for face recognition and image classification datasets with anomalies, obtaining promising results for the running time parameters. This work contributes to the growing field of quantum machine learning applications, and the algorithm's simplicity makes it easily adoptable by future quantum machine learning practitioners.We propose a quantum machine learning algorithm for data classification, inspired by the seminal computer vision approach of eigenfaces for face recognition.

基于量子机器学习的图像识别算法的改进

Jincheng Zhang

This paper presents a novel approach to image recognition based on quantum machine learning (QML) techniques. Traditional machine learning algorithms often struggle with the complexities of real-world images, particularly in handling high-dimensional data and intricate patterns. This work investigates the potential of QML to address these limitations, specifically focusing on enhancing image recognition accuracy and speed. We propose a system that integrates quantum feature extraction and pattern recognition with a tailored quantum machine learning algorithm, aiming to surpass current limitations in handling complex visual environments. The core mechanism centers around leveraging quantum computation to accelerate data processing and improve the model's ability to identify subtle visual cues. This paper will detail the proposed QML framework, its implementation, experimental results demonstrating its efficacy, and a discussion of potential future research directions.This paper presents a novel approach to image recognition based on quantum machine learning (QML) techniques.
