It is generally believed that a quantum algorithm must in some way harness entanglement to be able to provide any significant speed-up over classical algorithms. \u00a0Unfortunately, the absence of microwave signals in the D-Wave processor, a system designed to implement quantum annealing, \u00a0makes full state tomography impractical, and has thus made characterization of entanglement difficult. \u00a0 In this talk I will review quantum annealing, and then discuss what we expect entanglement to look like during the annealing algorithm. \u00a0I will then describe some recent experiments performed with D-Wave processors aimed at uncovering evidence for entanglement.
