"Optical continuousvariable 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 continuousvariable 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 measurementbased quantum computation using continuousvariable systems, and I will report on their experimental realization, including the recent demonstration of a 10,000mode (!) cluster state. Issues related to error correction and fault tolerance  many of which remain open problems  will also be discussed.
