A scheme for generating cluster state with Josephson charge qubit

Abstract

Abstract:

Highly entangled states called cluster states are an universal resource for measurement based quantum computing (QC). Based on the Josephson charge qubits, a scheme for generating cluster states is proposed.The scheme is simple and easily manipulated, because any two charge qubits based on Josephson junction can be selectively and effectively coupled by a symmetric dc SQUID. Initially state can be generated via changing the gate voltages, and couple charge qubits by choosing the suitable parameters. All the devices in the scheme are within the current technology.

Key words: quantum optics, cluster state, superconducting qubit, Josephson junction
