- 요약Quantum information science holds the promise of revolutionizing information processing and communication through advancements in quantum computing and quantum communications. Quantum key distribution (QKD) stands out as a method offering unconditional security in communications, particularly with the looming threat that quantum computers pose to traditional cryptographic systems. While existing QKD systems predominantly focus on long-distance communication, future quantum networks are likely to involve the integration of fixed nodes with highly mobile platforms to facilitate the "last mile'' communication between users. In this dissertation, I present a full system design of a QKD system specifically developed for implementation on highly mobile platforms such as drones and cars.Designing a QKD system for highly mobile platforms poses a formidable challenge, demanding careful consideration of the trade-space of system performance and size, weight, and power (SWaP). In the first part of this thesis, I discuss the design considerations for developing such a platform, culminating in a system using a polarization-based prepare-and-measure BB84 QKD protocol with decoy states. This system is designed with two field-programmable gate arrays, three resonant-cavity LEDs, and off-the-shelf passive optics and detectors. The transmitter platform has a SWaP of 1803 cm3, 2017 g, and 2453 mW. The receiver has a SWaP of 2728 cm3, 2678 g, and 5886 mW.The usage of multiple sources can increase the risk of side channel attacks in a QKD system due to the indistinguishability of the quantum states' spectral, temporal and spatial degrees-of-freedom. Other similar studies, have relaxed system security requirements to achieve SWaP metrics with the idea that these attack vectors will be addressed in the future. In this work, great effort is dedicated to ensuring that all sources are as indistinguishable as possible. The remaining distinguishability is quantified as the mutual information fraction of the final sifted key that an eavesdropper (Eve) would know after making temporal and/or spectral measurements on every state that is sent. This information is key for error correction and privacy amplification. The mutual information fraction leaked is 2.39x10-5 (with a 2.44x10-5 measurement bias, and uncertainty of 1.20x10-5) for the spectra, and 4.31x10-5 (with a 3.18x10-6 measurement bias and a 7.99x10-7 uncertainty) for the temporal degree-of-freedom.In the latter part of this thesis, I discuss the pointing-and-tracking (PAT) mechanism that is used to integrate our QKD system with highly mobile platforms. With the QKD system and PAT mechanisms combined, we perform experiments in different configurations, such as drone-to-drone and drone-to-car. Likely the most important metric for a QKD system is the secure key rate. In these experiments, we obtain secure key rates of 7.98 Kbits/s for drone-to-drone QKD and 1.52 Kbits/s for drone-to-car QKD.This thesis contributes to the advancement of quantum communication technology by providing insights into the design, implementation, and future prospects of QKD systems tailored for highly mobile platforms, paving the way for reconfigurable quantum networks.
