碱土金属原子作为少量子比特量子寄存器

Alkaline-Earth-Metal Atoms as Few-Qubit Quantum Registers

Alexey V. Gorshkov, Ana Maria Rey, Andrew J. Daley, Martin M. Boyd, Jun Ye, Peter Zoller, Mikhail D. Lukin

摘要:

我们提出并分析了一种新的量子信息处理方法,在该方法中,多个量子比特可以使用与光晶格中捕获的单个碱土原子相关的电子和核自由度进行编码和操纵。具体来说,我们描述了如何在每个寄存器内的量子位可以单独操纵和测量亚波长光学分辨率。我们还展示了这种少量子位寄存器如何通过条件隧道在光学超晶格中相互耦合,形成可扩展的量子网络。最后,讨论了量子计算和精密测量的潜在应用。

英文摘要:

We propose and analyze a novel approach to quantum information processing, in which multiple qubits can be encoded and manipulated using electronic and nuclear degrees of freedom associated with individual alkaline-earth atoms trapped in an optical lattice. Specifically, we describe how the qubits within each register can be individually manipulated and measured with sub-wavelength optical resolution. We also show how such few-qubit registers can be coupled to each other in optical superlattices via conditional tunneling to form a scalable quantum network. Finally, potential applications to quantum computation and precision measurements are discussed.
