Understanding quantum physics requires a solid foundation in mathematics, particularly linear algebra, multivariable calculus, and some probability and statistics. The textbook "Introduction to Quantum Mechanics" by David J. Griffiths is highly recommended for its comprehensive approach, though it assumes some prior knowledge. For those new to the subject, it's essential to grasp concepts like inner products and eigenvalues, as quantum mechanics is heavily based on the language of Hilbert spaces and linear operators. For beginners, "The Structure and Interpretation of Quantum Mechanics" by Hughs is suggested, as it introduces necessary mathematical concepts alongside quantum theory. Additionally, "QM Demystified" is recommended as a preparatory text before tackling more advanced quantum mechanics literature. Overall, a blend of mathematical study and introductory quantum mechanics texts will facilitate a better understanding of the subject.
