论文摘要
偶极子 - phonon量子逻辑(DPQL)利用了极性分子离子与被困的库仑晶体的运动模式之间的相互作用,以提供量子信息科学的潜在可扩展途径。在这里,我们研究了用于DPQL,阳离子碱 - 地铁一氧化物和单硫化物的一类候选分子离子,它们具有适合DPQL的结构,并且可以在现有的原子离子实验中产生,几乎没有其他复杂性。我们介绍了这些分子之一的DPQL操作的计算,即CAO $^+$,并讨论了实现实现的进展。我们还进一步开发了DPQL理论,包括状态制备和测量和纠缠多个分子离子。
Dipole-phonon quantum logic (DPQL) leverages the interaction between polar molecular ions and the motional modes of a trapped-ion Coulomb crystal to provide a potentially scalable route to quantum information science. Here, we study a class of candidate molecular ions for DPQL, the cationic alkaline-earth monoxides and monosulfides, which possess suitable structure for DPQL and can be produced in existing atomic ion experiments with little additional complexity. We present calculations of DPQL operations for one of these molecules, CaO$^+$, and discuss progress towards experimental realization. We also further develop the theory of DPQL to include state preparation and measurement and entanglement of multiple molecular ions.
