Efficient factorization with a single pure qubit and log N mixed qubits

Abstract

It is commonly assumed that Shor's quantum algorithm for the efficient factorization of a large number N requires a pure initial state. Here we demonstrate that a single pure qubit together with a collection of log2 N qubits in an arbitrary mixed state is sufficient to implement Shor's factorization algorithm efficiently.
