M. S. Tame, M. Paternostro, M. S. Kim, V. Vedral

摘要:

我们解决了自然的三量子比特相互作用的单向量子计算(\QC)的计算能力的影响。使用更复杂的纠缠结构的一个好处是能够用有限的资源构建量子算法的紧凑和经济的模拟。我们表明,我们的研究的特点体现在适当制备的光晶格,有效的三自旋相互作用已在理论上得到证明。我们使用它来为Toffoli门提供紧凑的结构。信息流和两个量子比特的相互作用也概述了,连同一个简短的分析相关的不完美的来源。

英文摘要:

We address the effects of natural three-qubit interactions on the computational power of one-way quantum computation (\QC). A benefit of using more sophisticated entanglement structures is the ability to construct compact and economic simulations of quantum algorithms with limited resources. We show that the features of our study are embodied by suitably prepared optical lattices, where effective three-spin interactions have been theoretically demonstrated. We use this to provide a compact construction for the Toffoli gate. Information flow and two-qubit interactions are also outlined, together with a brief analysis of relevant sources of imperfection.
