SUMMARY:A photonic cluster state machine gun - Terry Rudolph (Imperial Col

DESCRIPTION:Cluster states are multi-qubit entangled states which have the
  remarkable property that\, once prepared\, they can be used to perform qu
 antum computation by making only single qubit measurements. The problem of
  constructing a quantum computer therefore reduces to that of preparing th
 ese states. Over the last few years one of the more promising architecture
 s for doing so has been single photon optics. However the resource require
 ments are still prohibitive. In this talk I will discuss a way of turning 
 a single photon source - in particular one built from a self-assembled qua
 ntum dot - into a device capable of firing out long strings of entangled c
 luster state. Such a device would reduce the resource requirements for opt
 ical quantum computing by many orders of magnitude.\n
