Abstract

一个其他的简单计划被建议由在 two-qubit 操作期间使用单个看台波浪激光脉搏在套住的离子实现 two-qubit 格罗弗搜索算法。计划对加热震动的运动感觉迟钝，鉴于 decoherence，它是重要的。而且第三个辅助内部电子状态被消除，并且 qubit 定义是为两个离子的一样，它使实验更容易、更简单。

Addendum to “Grover search with pairs of trapped ions”

Zhenyu Xu, Mang Feng

The authors call attention to a previous work [M. Feng, Phys. Rev. A 63, 052308 (2001)] for Grover search by trapped ions in decoherence-free subspace (DFS). A scheme for a two-qubit conditional-phase flip gate in DFS is presented as a supplement.

Grover search with pairs of trapped ions

Mang Feng

The desired interference required for quantum computing may be modified by wave-function oscillations for the implementation of quantum algorithms [Phys. Rev. Lett. 84, 1615 (2000)]. To diminish such a detrimental effect, we propose a scheme with trapped ion pairs as qubits and apply the scheme to the Grover search. It will be shown that our scheme cannot only carry out a full Grover search, but can also meet the requirement for scalable hot-ion quantum computing. Moreover, the ion-pair qubits in our scheme are more robust against decoherence and the dissipation caused by the environment than single-particle qubits proposed before.

Grover search algorithm in an ion trap system

Zheng Shi-Biao

Two schemes for the implementation of the two-qubit Grover search algorithm in the ion trap system are proposed. These schemes might be experimentally realizable with presently available techniques. The experimental implementation of the schemes would be an important step toward more complex quantum computation in the ion trap system.
