[EN] In a world in which accessible information grows exponentially, the selection of the appropriate information turns out to be an extremely relevant problem. In this context, the idea of Machine Learning (ML), a subfield of Artificial Intelligence, emerged to face problems in data mining, pattern recognition, automatic prediction, among others. Quantum Machine Learning is an interdisciplinary research area combining quantum mechanics with methods of ML, in which quantum properties allow for an exponential speed-up in the algorithms. This field is currently one of the main research areas in companies like Google and Microsoft, due to the revolution that they could provide in data management.
Quantum computing has been proven to excel in factorization issues and unordered search problems due to its capability of quantum parallelism. This unique feature allows exponential speed-up in solving certain problems. However, this advantage does not apply universally, and challenges arise when combining classical and quantum computing to achieve acceleration in computation speed. This paper aims to address these challenges by exploring the current state of quantum machine learning and benchmarking the performance of quantum and classical algorithms in terms of accuracy. Specifically, we conducted experiments with three datasets for binary classification, implementing Support Vector Machine (SVM) and Quantum SVM (QSVM) algorithms. Our findings suggest that the QSVM algorithm outperforms classical SVM on complex datasets, and the performance gap between quantum and classical models increases with dataset complexity, as simple models tend to overfit with complex datasets. While there is still a long way to go in terms of developing quantum hardware with sufficient resources, quantum machine learning holds great potential in areas such as unsupervised learning and generative models. Moving forward, more efforts are needed to explore new quantum learning models that can leverage the power of quantum mechanics to overcome the limitations of classical machine learning.
The field of quantum computing is in the midst of a period of transformation as a result of the recent discovery of quantum entanglement. It is designed to perform computations that classical computers cannot handle since it is based on and operates in compliance with the rules of quantum mechanics. Because it operates on certain premises, it enables this to happen. Quantum bits, also known as qubits, have the unique ability to represent many states at once, unlike their conventional analogues. However, classical bits can only take on the values 0 or 1, and no other values in between. Quantum bits are capable of existing in a wide variety of states simultaneously. As a result of their unique ability to explore multiple solutions at once, quantum computers have the potential to dramatically boost the processing speed with which certain problems may be solved. Furthermore, qubits can show entanglement, in which the state of one qubit becomes intertwined with the state of another qubit, even if the qubits are separated by a great distance. Quantum entanglement describes this strange occurrence. This entanglement provides the way for the creation of new algorithms and enhanced computing power by simplifying the execution of complex interactions. Although difficulties like qubit stability and error correction must be overcome, quantum computing has the potential to revolutionize many different areas, including cryptography, optimization, and scientific discovery. Although significant strides have been made, the implementation of large-scale quantum computers remains in its infancy, necessitating ongoing research and development.
In the realm of artificial intelligence (AI), the integration of quantum computing with machine learning (ML) has sparked a significant shift in how we approach problems that were once deemed computationally infeasible. Quantum Machine Learning (QML) represents an exciting intersection of quantum mechanics and machine learning, potentially revolutionizing areas such as optimization, pattern recognition, and data analysis. Although quantum computing itself is still in its infancy, the synergy between quantum theory and classical machine learning algorithms promises to unlock new capabilities that classical computing could never achieve. This paper delves into the latest advancements in Quantum Machine Learning, its theoretical underpinnings, practical applications, and the challenges that researchers face as they explore this rapidly growing field.
Quantum physics offers a new paradigm that promises to make certain computations faster and more efficient.The recent progress of quantum computers allows for more complex applications which lead to a rising interest in transferring machine learning methods to quantum hardware for practical applications.However, the development of quantum computers is still in its beginnings and currently these approaches require synergy with classical computers.We present some methods where this quantum-classical interplay is used to enhance machine learning approaches.
The world's most difficult problem during the preceding decade was the big data problem. The big data challenge refers to the fact that data is growing at a much faster rate than computational rates. People, as well as virtually all organizations and scientific institutions, are keeping a rising amount of data as the cost of storage falls every day. Large amounts of data are generated by social activities, scientific inquiries, biological discoveries, and sensor devices. Big data is beneficial to society and economy, but it also poses challenges to scientific communities. Traditional tools, machine learning algorithms, and methodologies cannot handle, manage, or analyze large amounts of data. Quantum computing, in the realm of Big Data, allows businesses to collect and analyze large volumes of data quickly using quantum algorithms. Separate data sets may be detected, analyzed, integrated, and diagnosed with far greater ease. To find patterns, all of the items of a large database can be studied at the same time. As a result, it may be years before quantum computing makes its way into most businesses or becomes a common data analytics tool. Quantum computing will still be a relatively new technology in 2021. Machine learning algorithms are currently improving thanks to breakthroughs in quantum computing technology. There's still a lot to learn about quantum computing's capabilities and the implications of such a strong technology.
