SUMMARY OR ABSTRACT
Text of Note
There is currently a great interest in using high-dimensional (dimension d > 2) quantum states for various communication and computational tasks. High-dimensional quantum states provide an efficient and robust means of encoding information, where each photon can encode a maximum of log2d bits of information. One application where this becomes a significant advantage is quantum key distribution (QKD), which is a communication technique that relies on the quantum nature of photonic states to share a classical secret key between two remote users in the presence of a powerful eavesdropper. High-dimensional QKD protocols are believed to overcome some of the practical challenges of the conventional qubit-based (d = 2) protocols, such as the long recovery time of the single-photon detectors, or the low error tolerance to quantum channel noise.
