Ascheme for implementing the Deutsch-Jozsa algorithm is proposed by using two superconducting quantum interference devices interact with a cavity resonantly.The scheme can be realized more easily within current experi mental technology.
We propose a scheme of implementing the Deutsch–Jozsa algorithm based on superconducing charge qubits, which would be a key step to scale more complex quantum algorithms and very important for constructing a real quantum computer via superconducting charge qubits. The present scheme is simple but fairly efficient, and easily manipulated because arbitrary two-qubit can be selectively and effectively coupled by a common inductance. More manipulations can be carried out before decoherence sets in. The proposed scheme is in line with current technology.
