“The book under review summarises lecture notes presented by the author for the quantum machine learning MSc course at the University of Trento; it is therefore structured in a student-friendly manner, offering support both on the mathematical side (also with the interpretation of quantum mechanics) and on the algorithmic side. ... The book concludes with an extensive, well-curated set of references, which represent an excellent continuation of quantum approaches.” (Irina Ioana Mohorianu, zbMATH 1530.68003, 2024)
