  From the philosopher's perspective, the interest in quantum computation stems
primarily from the way that it combines fundamental concepts from two distinct
sciences: physics (especially quantum mechanics) and computer science, each
long a subject of philosophical speculation and analysis in its own right.
Quantum computing combines both of these more traditional areas of inquiry into
one wholly new (if not quite independent) science. There are philosophical
questions that arise from this merger, and philosophical lessons to be learned.
Over the course of this chapter we discuss what I take to be some of the most
important.
