Recently, very large entangled states of light have been generated using multiplexing techniques. I will explore some experiments that have successfully shown multiplexing to be a viable approach in increasing the scalability of quantum systems. Specifically, I will focus on experiments in the time domain, as well as the spatial domain, with a brief discussion on frequency domain experiments. There are some nice consequences when dealing with spatial domain multiplexing that lead to the ability to be able to program linear optics networks. I will discuss some results using this architecture, including collaborative work with Peking University.

I will also explore how these large entangled states may be used for measurement-based quantum computing.
