“…In the definition of quantum control as “tuning quantum interactions between matter and field, or field‐field interaction,” the D ‐controller would fall in the first category as, eg, the electric fields from the gate electrodes control the energy levels of electrons in quantum dots. Here, as in the work of Dong et al, the D ‐controller is taken time‐invariant, but spatially varying. In the aforementioned work, the spatially varying controller is implemented by spatially modifying the dielectric constant of the medium of a wave guide.…”

“…Here, as in the work of Dong et al, the D ‐controller is taken time‐invariant, but spatially varying. In the aforementioned work, the spatially varying controller is implemented by spatially modifying the dielectric constant of the medium of a wave guide. This has some commonality with our spatially varying bias field approach; however, our D ‐controller approach seems more related to the DiVincenzo architecture …”

“…Attempts at classifying the many quantum control laws abound, but here we will particularly retain the classification of [5], which emphasizes, as the present paper does, time-invariant spatially-distributed control. Control is defined in [5] as manipulating matter-field or fieldfield interactions. In this classification, our approach is rather a fieldfield interaction, or in other words our controller is field-mediated.…”

“…The same pattern holds for the logarithmic sensitivity, where the expressions in Eqs. (5) are divided by the error, that is, 1 − | OUT|Ψ(t f (m)) | 2 , as shown in Fig. 2.…”
