Entropic Uncertainty Relations via Direct-Sum Majorization Relation for Generalized Measurements
Kyunghyun Baek, Hyunchul Nha, Wonmin Son
We derive an entropic uncertainty relation for generalized positive-operator-valued measure (POVM) measurements via a direct-sum majorization relation using Schur concavity of entr…

Efficient High-dimensional Quantum Key Distribution with Hybrid Encoding
Yonggi Jo, Hee Su Park, Seung-Woo Lee +1
We propose a schematic setup of quantum key distribution (QKD) with an improved secret key rate based on high-dimensional quantum states. Two degrees-of-freedom of a single photon,…

Enhanced Bell state measurement for efficient measurement-device-independent quantum key distribution using 3-dimensional quantum states
Yonggi Jo, Kwangil Bae, Wonmin Son
We propose an enhanced discrimination measurement for tripartite 3-dimensional entangled states in order to improve the discernible number of orthogonal entangled states. The schem…
