Quantum Mechanics as a Simple Generalization of Classical Mechanics
arXiv:quant-ph/0204015 · doi:10.1007/s10701-009-9324-7
Abstract
A motivation is given for expressing classical mechanics in terms of diagonal projection matrices and diagonal density matrices. Then quantum mechanics is seen to be a simple generalization in which one replaces the diagonal real matrices with suitable Hermitian matrices.
