A quantum network will consist of many physically separated nodes connected by quantum communication channels that distribute entanglement between them. Such nodes will require mechanisms for the generation, routing, and measurement of quantum states to fulfill a communication protocol between any two quantum nodes. The aim of this work is to develop portable/rack-mounted, low-cost, robust, and reliable tools that can be deployed anywhere into a quantum network testbed. The prototypes are, by-design, integrated into a 19" rack to allow for the easy deployment into anywhere with standard networking infrastructure. These prototype source and receiver systems will serve as benchmarking devices for the implementation of metrology protocols in quantum network testbeds. Measurements performed using this toolset have shown a fidelity of more than 0.98 with a polarization entanglement visibility of 0.97.
