Quantum communication, based on the principles of quantum mechanics, offers unprecedented levels of security and information processing capabilities. However, harnessing the full potential of quantum communication requires sophisticated electronics and precise control. For efficient field level implementation of quantum key distribution (QKD) protocols, it is crucial to employ highly efficient control electronics that can optimize and stabilize the system's characteristics. Our work focuses on the study of opto-electronics systems required in quantum communication and the design and development of the same. We aim to develop the electronics for both the transmitter and receiver components, encompassing laser sources, single photon detectors, and modulators. As an initial step, gated quenching scheme has been implemented for evaluating a single photon avalanche diode (SPAD) evaluation board using FPGAs. Additionally, circuit and PCB designs have been developed for the readout electronics required for coincidence measurements in QKD. The primary objective of this research is to devise compact, efficient, and cost-effective opto- electronic systems for quantum communication.
