High-dimensional quantum key distribution using a multi-plane light converter
Ohad Lib, Kfir Sulimany, Mateus Araújo +2
High-dimensional quantum key distribution (QKD) offers higher information capacity and stronger resilience to noise compared to its binary counterpart. However, these advantages ar…
