At the core of most quantum technologies is the development of homogeneous, long lived qubits with excellent optical interfaces, and the development of high efficiency and robust optical interconnects for such qubits. To overcome inhomogeneities in semiconductor spin qubits and in their connections, we have been relying on fast photonics inverse design and on optimization (Floquet engineering) of the qubits themselves. We illustrate this approach to scalable semiconductor quantum systems with our results on quantum photonics based on diamond and silicon carbide.
