A scheme for distributed quantum search through simultaneous state transfer mechanism

A scheme for distributed quantum search through simultaneous state transfer mechanism Using a quantum network model, we present a scheme for distributed implementation of Grover's algorithm. The proposed scheme can implement a quantum search over data bases stored in different computers. Entanglement is used to carry out different non‐local operations over the spatially distributed quantum computers. A method to transfer the combined state of many qubits over the entanglement and subsequently refreshing the entangled pair is presented. This method of simultaneous s tate transfer from one computer to the other, is shown to result in a constant communication complexity. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Annalen Der Physik Wiley

Abstract

Using a quantum network model, we present a scheme for distributed implementation of Grover's algorithm. The proposed scheme can implement a quantum search over data bases stored in different computers. Entanglement is used to carry out different non‐local operations over the spatially distributed quantum computers. A method to transfer the combined state of many qubits over the entanglement and subsequently refreshing the entangled pair is presented. This method of simultaneous s tate transfer from one computer to the other, is shown to result in a constant communication complexity.
