我们提出了一种大规模量子计算机架构，通过在非常简单的陷阱几何结构中更容易地稳定单个大型线性离子链。通过将离子限制在离子间距几乎均匀的非谐波线性陷阱中，我们表明，基于与形状简单的激光脉冲的近连续横向运动模式的耦合，可以在多普勒温度下在大型线性离子晶体中实现高保真量子门。版权所有 (C) EPLA，2009
We propose a large-scale quantum computer architecture by more easily stabilizing a single large linear ion chain in a very simple trap geometry. By confining ions in an anharmonic linear trap with nearly uniform spacing between ions, we show that high-fidelity quantum gates can be realized in large linear ion crystals under the Doppler temperature based on coupling to a near-continuum of transverse motional modes with simple shaped laser pulses.
