Quantum Machine Learning (QML) is a field combining quantum computing and artificial intelligence to enhance data-driven tasks by leveraging quantum computational advantages.
The review explores how QML can address computational bottlenecks in classical machine learning, particularly for complex datasets.
Key areas of focus include quantum data encoding, learning theory, optimization techniques, and applications in quantum chemistry and sensing.
Challenges like Noisy Intermediate-Scale Quantum (NISQ) devices are discussed, highlighting the need for quantum-native algorithms and improved error correction for practical deployment.
