Physical Resources, Entanglement, and the Power of Quantum Computation

by Prof. Carlton M. Caves (Univ. of New Mexico)

ABSTRACT

Requiring that a quantum computer not need an exponentially growing 
amount of any physical resource places stringent constraints on the 
systems that can act as quantum computers.  In particular, a quantum 
computer must be made up of subsystems, usually qubits, thus ruling 
out implementing a quantum computer in a single atom or by using the 
interference of classical waves.  Furthermore, if a quantum computer 
made up of subsystems performs some computation exponentially faster 
than any classical computer, there must be global entanglement among 
all the subsystems at some point during the computation.  Having thus 
led up to the conclusion that quantum entanglement is the essential 
ingredient for quantum computation, I will discuss why this 
conclusion isn't ironclad.
