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 log(2)N qubits in an arbitrary mixed state, is sufficient to implement Shor's factorization algorithm efficiently.
