We considered a few aspects of quantum computing in connection with the time series analysis. Quantum Fourier Transform was selected as a test example due to its important practical value in spectral analysis, the easiness of implementation and its generic nature with respect to many other quantum algorithms. The obvious drawbacks have been identified preventing the straightforward application of Quantum Fourier Transform to the evolving times series. The limited available register size of a quantum computer may be an issue at the data postprocessing stage, but carry significant practical value if included into the data acquisition stage. The analyzed qubit by qubit procedure is favoring the way most of the time series are acquired, which is one at a time. This procedure should be necessarily considered with the decoherence issue for the big quantum systems and long evolution times.

Because of the rotational components on quantum circuits, some quantum neural networks based on variational circuits can be considered equivalent to the classical Fourier networks. In addition, they can be used to predict the Fourier coefficients of continuous functions. Time series data indicates a state of a variable in time. Since some time series data can be also considered as continuous functions, we can expect quantum machine learning models to do many data analysis tasks successfully on time series data. Therefore, it is important to investigate new quantum logics for temporal data processing and analyze intrinsic relationships of data on quantum computers. In this paper, we go through the quantum analogues of classical data preprocessing and forecasting with ARIMA models by using simple quantum operators requiring a few number of quantum gates. Then we discuss future directions and some of the tools/algorithms that can be used for temporal data analysis on quantum computers.

Traditional methods often struggle with the complexity of such sequences, limiting their analytical and modeling potential. We propose a quantum-enhanced algorithm that leverages quantum superposition and entanglement to achieve more accurate and efficient analysis, addressing limitations inherent in classical approaches. This work explores the potential of quantum computation to transform the analysis of non-linear time series data, offering a promising avenue for advanced modeling and forecasting. The core mechanism involves a quantum-enhanced Fourier transform coupled with a tailored optimization algorithm. The paper details the algorithm's design, implementation, and preliminary results demonstrating improved accuracy and efficiency compared to established classical methods. Finally, we discuss the challenges and future directions for this technology.
Fast data and growing artificial intelligence have brought traditional computer infrastructures to their limits. They expose inherent limitations in processing speed, energy efficiency, and scalability. In the face of nearing physical barriers with Moore's Law and memory bottlenecks plaguing traditional von Neumann architectures, quantum computing offers a completely new way of leveraging principles such as superposition and entanglement to redefine computation possibilities. This review is concerned with addressing how quantum computing stands to do that foundational AI and big data challenges, from accelerating extremely complex optimization tasks to enabling very secure, real-time analytics. These topics include basic principles of quantum mechanics, the basis of qubits and quantum circuits; updates in quantum algorithms (such as Grover's search, quantum annealing); and hybrid classical-quantum systems that serve as pathways through technological gaps. The paper suggests major applications of transformative nature in some of the higher-impact domains: quantum-accelerated drug discovery for health, portfolio optimization in finance, and quantum-secured communication infrastructures to guard the IoT. Case studies present early successes on quantum machine learning models improving diagnostic accuracy and annealing-based traffic optimization for urban congestion. Decoherence, error-prone devices, as well as low software ecosystems are conspiring against the actual roadways to practical quantum advantages. Future progress is dependent on the innovative development of error-corrected qubits, scalable algorithms, as well as interdisciplinary collaboration. While universal quantum supremacy remains while unreached, this coming decade promises a series of developments toward applied, specific applications that will place quantum computing as an added force among the classical systems. This review tries to project both sides of the likely potential of the space, obstacles, and path, paving the way for the researcher to find their foot in the continually progressing quantum-AI terrain.
