Long-distance entanglement sharing using hybrid states of discrete and continuous variables

S Bose, J Singh, A Cabello, H Jeong - Physical Review Applied, 2024 - APS
We introduce a feasible scheme to produce high-rate long-distance entanglement that uses
hybrid entanglement between continuous variables (CVs) and discrete variables (DVs). We …

Experimental storage of photonic polarization entanglement in a broadband loop-based quantum memory

CJ Evans, CM Nunn, SWL Cheng, JD Franson… - Physical Review A, 2023 - APS
We experimentally study the ability of a broadband “loop-and-switch” type quantum memory
device to store entanglement. We find that one active loop-based memory and one passive …

Quadrature Entanglement in Cascaded Down Conversion for Multiparty Continuous Variable Quantum Key Distribution

S Singla - 2024 - authorea.com
A multiparty continuous-variable quantum key distribution (CVQKD) algorithm still remains to
be shown, which is the goal of this paper. In contrast to pair-wise discrete quantum key …
