Talk Title: "Optical continuous-variable cluster states: theory and experiment"

Abstract:

Cluster states are an entangled resource state that enable quantum computing using adaptive measurements alone. This is surprising when one considers what this means: one can quantum compute simply by *looking* at a quantum systems in a particular way! The continuous-variable incarnations of these states are simple to make using lasers and can be scaled up with ease. In this talk, I will describe the theoretical underpinnings of measurement-based quantum computation using continuous-variable systems, and I will report on their experimental realization, including the recent demonstration of a 10,000-mode (!) cluster state. Issues related to error correction and fault tolerance -- many of which remain open problems -- will also be discussed.
