February 24, 2025• Physics 18, 40The demonstration that ions can be precisely manipulated in a trap containing integrated photonics paves the way for a large-scale trapped-ion quantum processor. C. Mordini et al. [6] Figure 1: Mordini and colleagues present building blocks for a quantum computer whose quantum bits are trapped ions (purple) [6]. Individual ions are transported above surface electrodes (light orange), which are patterned on a dielectric material (light gray) and have integrated p...
