High-dimensional quantum key distribution based on multicore fiber using silicon photonic integrated circuits

Silicon chip-to-chip high-dimensional quantum key distribution Quantum key distribution (QKD) enables ultimate secure communication guaranteed by quantum mechanics. Most of QKD systems are based on binary encoding utilizing bulky, discrete, and expensive devices. Consequently, a large scale deployme...
