What if you can reprogram the beam splitters to move into different positions? Say the beam splitters can be actuated to different positions and angles automatically via code. Then you can build a general purpose rig, that can be reprogrammed to solve different quantum functions. Then you can build clones of this rig. And stack them up in racks. And have thousands of racks. Now you have a super quantum computer system. Then you can begin to miniaturizing the system. The Chinese quantum supremacy solution only solved one problem. But I would gather that the beam splitters can be modified to solve other quantum functions.
