SCHEME FOR IMPLEMENTING THE DEUTSCH–JOZSA ALGORITHM IN ION-TRAP SYSTEM

Abstract

We propose a scheme for implementing the Deutsch–Jozsa algorithm in ion-trap system. The scheme is based on resonant sideband excitation, which only requires resonant interactions. Thus the scheme is very simple and the quantum dynamics operation can be realized at a high speed, which is important in view of decoherence. The required experimental techniques are within the scope of what can be obtained in the ion-trap setup.

Scheme for implementing the Deutsch-Jozsa algorithm in cavity QED

Shi-Biao Zheng

We propose a scheme for realizing the Deutsch-Jozsa algorithm in cavity QED. The scheme is based on the resonant interaction of atoms with a cavity mode. The required experimental techniques are within the scope of what can be obtained in the microwave cavity QED setup. The experimental implementation of the scheme would be an important step toward more complex quantum computation in cavity QED.

IMPLEMENTATION OF TWO-QUBIT DEUTSCH–JOZSA ALGORITHM WITH TRAPPED IONS

Zhiming Zhan

In this paper, we propose a scheme to implement two-qubit Deutsch–Jozsa algorithm with trapped ions. The distinct advantage of the scheme lies in the fact that it does not use the vibrational mode as the data bus. The vibrational mode is only virtually excited, which makes our scheme insensitive to heating provided that the system remains in the Lamb–Dicke regime.

Implementation ofn-qubit Deutsch–Jozsa algorithm using resonant interaction in cavity QED

Hong‐Fu Wang, Zhang Shou

We propose a scheme to implement the n -qubit Deutsch–Jozsa algorithm based on resonant interaction between the atoms and a single-mode cavity. In the scheme, the resonant transitions between two ground states and one excited state of an atom are changed alternately by adjusting the cavity frequency appropriately, and the operations required to complete the algorithm can be significantly simplified following the increment of the number of qubits. The implementation of the scheme in experiment would show the full power of quantum algorithm and would be significative and important for more complicated quantum algorithm in cavity quantum electrodynamics.

Efficient Scheme for Greenberger–Horne–Zeilinger State and Cluster State with Trapped Ions

Zhiming Zhan, Wen‐Xing Yang, Weibin Li +1 more

We propose a scheme to generate the Greenberger–Horne–Zeilinger (GHZ) states and the cluster states of many trapped ions. In the scheme, the ion is illuminated by a single laser tuned to the first lower vibrational sideband. The scheme only requires resonant interactions. Thus the scheme is very simple and the quantum dynamics operation can be realized at a high speed, which is important in view of decoherence.

Implementation of Deutsch-Jozsa Algorithm Via Cavity QED

Mei Jin-feng

A scheme for the implementation of the two-qubit Deutsch-Jozsa algorithm using cavity QED was proposed.The advantages of the proposal are demonstrated as follows.One is that the cavity feld is only virtually excited and the photon-number-dependent part in the effective Hamiltonian is cancelled so that the system is insensitive to the cavity decay and the thermal field.The other one is that we don't require any Hadamard operation,which makes the schematic setup simple.Therefore,the present scheme is available based on the current technologies.

Implementing Deutsch–Jozsa Algorithm in Cavity QED

Dong Ping, Song Wei, Zhuo‐Liang Cao

We propose a simple scheme for implementing Deutsch–Jozsa algorithm in cavity QED. Our scheme is insensitive to both the cavity decay and thermal field because we use the large-detuned interaction. The scheme would be important to constructing practical computer in cavity QED system.
