论文摘要
极性分子的内部状态可以通过微波频率电偶极转换来控制。如果施加的微波电场具有空间梯度，这些转变也会影响这些偶极颗粒的运动。该功能可用于设计声子介导的量子门，例如捕获的极性分子离子量子置量没有激光照明，无需在运动基态附近冷却。结果是用于热运动中偶极子的高速量子处理工具箱，将固态量子矩的精确微波控制与被困的离子量子A的较长相干时间结合在一起。
Internal states of polar molecules can be controlled by microwave-frequency electric dipole transitions. If the applied microwave electric field has a spatial gradient, these transitions also affect the motion of these dipolar particles. This capability can be used to engineer phonon-mediated quantum gates between e.g. trapped polar molecular ion qubits without laser illumination and without the need for cooling near the motional ground state. The result is a high-speed quantum processing toolbox for dipoles in thermal motion that combines the precision microwave control of solid-state qubits with the long coherence times of trapped ion qubits.
