This thesis is composed of two sections. In the first section, a spin to charge conversion protocol was implemented for use in single diamond nitrogen-vacancy (NV) centers. The second section focuses on the modeling and testing of the performance of a quantum computer-based joint detection receiver (JDR) to demonstrate an advantage in coherent state discrimination over a single detection receiver (SDR). Included is the realistic modeling of the noise induced by an opto-electro-mechanical transduction mechanism.
