Random circuits by measurements on weighted graph states

Year: 2008

Type: article

Abstract: Random quantum circuits take an input quantum state and randomize it. This is a task with a growing number of identified uses in quantum-information processing. We suggest a scheme to implement random circuits in a weighted graph state. The input state is entangled with the weighted graph state and a random circuit is implemented when the experimenter performs local measurements in one fixed basis only. The scheme uses no classical random numbers and is a new and natural application of weighted graph states.
