Abstract

We propose a scheme for implementing quantum algorithms with resonant interactions. Our scheme only requires resonant interactions between two atoms and a cavity mode, which is simple and feasible. Moreover, the implementation would be an important step towards the fabrication of quantum computers in cavity QED system.

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 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.

Scheme for implementing quantum dense coding in cavity QED

Ye Liu, Guang‐Can Guo

An experimentally feasible scheme for implementing quantum dense coding in cavity QED is proposed. In the scheme the atoms interact simultaneously with a highly detuned cavity mode with the assistance of a classical field. The scheme is insensitive to the cavity decay and the thermal field. Bell states can be exactly distinguished via detecting the atomic state, and the quantum dense coding can be realized in a simple way.

A robust scheme for quantum information processing in cavity QED

Shi‐Biao Zheng

We propose a robust scheme for the implementation of two-qubit phase gates with a cavity QED system. After the gate operation the computational basis states are equally damped by the decoherence effect and thus the gate error is suppressed. The scheme is based on resonant atom–cavity interaction and thus the operation speed is high. During the atom–cavity interaction no external laser fields are required and thus the gate errors arising from external sources are suppressed.
