hello aspirant...

The first book on QM that i ever read was 'A QUANTUM MECHANICS PRIMER' by D.T.GILLESPIE

Though it's quite old now (1974), I think it is still one of the best starter texts on QM out there. It assumes no more on the part of the reader than familiarity with basic high-schools algebra,and complex numbers. It covers some important topics like ;

* EIGENVALUES AND EIGENVECTORS

* WAVEFUNCTIONS

* QUANTUM OBSERVABLES AND OPERATORS

* THE QUANTUM THEORY OF MEASUREMENT

* THE SCHRODINGER EQUATION

and many more such key topics.

HOPE IT WOULD HAVE HELPED YOU

ALL THE BEST
