As a central science case of this application we plan to join twounique features that are existing only for trapped Rydberg ions andhave no counterpart in the systems of neutral Rydberg atoms or intrapped ions in low electronic levels only - that is the combination ofelectric charge and large electric polarizability: The charge of trappedions provides a ideal means to control their position by applying timedependentelectric fields acting via the strong Coulomb interaction.Additionally, Rydberg ions exhibit a large polarizability in electricfields, and thus experiencing a different force. Consequently, we mayexcite a superposition state of ground state and Rydberg state, andexpose it to a time-depending electric field, generated by an up-anddownvoltage ramp applied to the trap control segments. Thisoperation will induce a back-and-forth ion shuttle, however acting witha different force to both electronic components of the wave-packet,which is equivalent to a relative state-depending phase shift. We willgenerate such way a single ion Schrödinger cate state and ademonstrate a novel type of fast two-ion gate operation.

作为这一应用的核心科学案例，我们计划加入两个独特的特征，这些特征只存在于被捕获的里德伯离子中，并且在中性里德伯原子或仅处于低电子能级的内插离子系统中没有对应物-这是电荷和大电极化率的组合：陷阱子的电荷提供了一种理想的手段，通过施加经由强库仑相互作用起作用的时间依赖性电场来控制它们的位置。此外，里德伯离子在电场中表现出很大的极化率，因此受到不同的力。因此，我们可以激发基态和里德伯态的叠加态，并将其置于依赖于时间的电场中，该电场由施加到陷阱控制段的上升和下降电压斜坡产生。这种操作将引起一个来回的离子穿梭，然而作用于波包的两个电子分量的力是不同的，这相当于一个依赖于状态的相对相移。我们将用这种方法产生单离子薛定谔阴极态，并演示一种新型的快速双离子门操作。
