As quantum computers become available to the general public, the need has arisen to train a cohort of quantum programmers, many of whom have been developing classical computer programs for most of their careers. The postulates of quantum mechanics are linear algebraic in nature, so it might appear surpris-ing that until recent work by Lloyd and co-authors (23; 22; 24) no quantum algorithms achieving speedups for linear algebra or machine learning problems had been proposed.
