- 요약Recent advances in quantum computing threaten the future of information security in classical cryptography. However, parallel advances in quantum communication and quantum key distribution (QKD) in particular show promise as a new paradigm for information security without the same vulnerabilities. Because the security of QKD does not depend on the computational power of the adversary, it can be considered "future proof". Nevertheless QKD brings its own set of technical challenges and security vulnerabilities that must be addressed to bring it forth as a practical option for secure information transfer.One outstanding issue is the so-called "last mile" problem wherein connecting a communication network to the end users requires significant expense and infrastructure. Mobile and reconfigurable communication platforms present advantages in this area due to their ability to meet the needs of many end users with a smaller network of nodes. The implementation of a QKD system on mobile platforms such as drones and cars brings this advantage to a hypothetical future quantum communication network. The security of QKD hinges on limiting an adversary to only performing measurements on the quantum state in the encoded degree-of-freedom of the wavepacket, at which point the attack can be detected and dealt with via privacy amplification. This involves preparing and measuring high fidelity quantum states with sufficient transmission volume to overcome the challenges of finite key effects. Additionally, it requires high levels of indistinguishability in the non-encoding degrees-of-freedom lest the information be leaked to the adversary via a side-channel attack.In this thesis, I present the designs and experimental efforts undertaken to implement a QKD system on mobile platforms and operated in an outdoor environment. I also present the detailed analysis, modeling, and data processing used to determine the central figures-of-merit for the performance of the system.I explain the light emitting diode (LED) based photonic source driven by a field-programmable gate array, along with the apparatus with which we collect the photonic wavepackets. These custom LED-to-fiber couplers can achieve mean photon numbers on the order of unity, which is as high an intensity as is optimal for most QKD protocols. As measures against potential side-channel attacks, the transmitter optics bench incorporates a single-mode spatial filter fiber and a spectral filter while the field-programmable gate array dynamically controls the timing of the wavepackets. For the indistinguishability of transmitted states, I derive the maximum mutual information that can be leaked to the adversary through side-channel attacks. The spectral degree-of-freedom yields a leaked mutual information of 2.4x10−5 (with a 2.44 x 10−5 measurement bias and uncertainty of 1.20 x 10−5 ). The temporal degree-of-freedom yields a leaked mutual information of 4.31 x 10−5 (with a 3.18 x 10−6 measurement bias and a 7.99 x 10−7 uncertainty).I describe the design of a full optical train for state preparation and measurement, including polarization fidelity compensation to combat the birefringent effects of the single-mode spatial filter fiber as well as other optical components. These designs are informed by experience in implementing tabletop versions of the system as well as extensive modeling of the non-ideal polarization properties of the components. Additionally, I detail the procedures required to effectively deploy this system on mobile platforms for outdoor field testing. The polarization preparation and measurement system is able to achieve average quantum bit error rates as low as 2.21% in field demonstrations.I introduce a suite of custom data analysis and processing software, which stitches together the asynchronous receiver data streams, synchronizes the data streams of the two users with a custom qubit-based Bayesian algorithm, generates sifted keys, and filters noise in the post-processing. The synchronization algorithm in particular allows the reconciliation of the two users' data streams without the need for external hardware solutions and without sacrificing any secure key. My simulations show that the algorithm can tolerate relative clock drift rates of up to 1 part in 4140.I present our team's demonstrations of this system in various mobile platform configurations in the context of relevant state-of-the-art QKD demonstrations in the literature. The primary figure-of-merit of the aggregate system is the finite secure key rate, and we achieve finite key rates of 7.98 kbits/s for the air-to-air demonstration, 1.52 kbits/s for the air-to-car demonstration, and 19.6 kbits/s for the car-to-car demonstration.
