    • Fast control over the tunnel coupling in gate-defined double-dots is challenging and has not been demonstrated yet. In other QD systems such as self-assembled or vertically stacked QDs tunnel coupling is fixed by fabrication

    • CNOT gate can also be implemented using the scheme proposed in Ref. , but this scheme requires biasing the two double-dots in opposite directions, so that the configuration: S(0,2)-S(2,0) is obtained. This bias position is very far from the low-bias symmetric point that is proposed in the current work for single qubit operations, and could be experimentally challenging
