Abstract
Quantum devices with chains of quantum dots for controlling tunable couplings between Majorana zero modes (MZMs) are described. Methods for controlling tunable couplings between MZMs using such chains of quantum dots are also described. An example quantum device comprises at least one superconducting island configurable to support at least one pair of Majorana zero modes (MZMs). The quantum device may further include a region adjacent to at least one MZM of the at least one pair of MZMs, where the region is configurable to realize a chain of quantum dots for controlling a tunable coupling between the at least one MZM of the at least one pair of MZMs and another MZM.
