is ensured by the sublinear dependence of the EXAM dimensions on the number of interconnected nodes. The experimental transport dynamics between the nodes is well-reproduced by a theoretical model of self-interacting IX fluids in a dynamic potential landscape, which successfully demonstrates the ability to design, simulate and test complex IX devices. The EXAM concept is extensive and compatible with the well-established acoustic transport and manipulation of quantum excitations by SAWs [@PVS152; @PVS171; @PVS265; @NPSne; @PVS223].

In the following section (Sec. II), we describe the sample fabrication details as well as the optical techniques employed for the detection of IX transport and multiplexing. The experimental results are then presented in Sec. \[Results\]. Here, we start with investigations of the dynamics of IXs under acoustic fields (Sec. \[Acoustic\_exciton\_transport\]), which demonstrate that SAW fields can capture IX packets and transport them over large distances. We then address the control of IX fluxes, which is carried out using EXATs (Sec. \[SecEXAT\]). In Sec. \[SecEXAM\], the flow control by EXATs is then combined with long-range acoustic transport to realize an IX multiplexer. Finally, Sec. \[Discussions\_and\_Conclusions\] discusses issues regarding the application of EXAMs as a building block for integrated electro-optical devices based on IXs and summarizes
