In the decade since the publication of the first edition of “Explorations in Quantum
Computing” the field has blossomed into a rich and diverse body of knowledge, and
tremendous progress has been made on building functional quantum computer hardware.
Yet I find that a discussion of applications of quantum computers still remains
largely confined to Shor’s algorithm for factoring composite integers and Grover’s
algorithm for quantum search. As more and more books have been written on quantum
computing this standard presentation has been reinforced, thereby overlooking
less well known, but arguably more interesting, applications
