We will discuss some new ideas and new experiments in optical quantum computing. In particular, we will present a new experiment in which a small scale quantum computer calculates the eigenvalues of an unknown matrix for the first time. Such an operation has direct relevance to Shor's factoring algorithm. We will also discuss the Boson Sampling problem, a classically hard problem, that, in principle, can be emulated efficiently by a simple optical quantum computer. We will examine the effect of errors on this problem.
