Characterisation of a satellite-to-ground channel for continuous variable quantum key distribution protocol
Emma Tien Hwai Medlock, Vinod N. Rao, Timothy P. Spiller +1
In space based quantum key distribution (QKD) protocols, the quantum channel will be dynamic in nature and the channel loss will change with respect to the zenith angle. In the con…
Information-Theoretic Solutions for Seedless QRNG Bootstrapping and Hybrid PQC-QKD Key Combination
Juan Antonio Vieira Giestinhas, Timothy Spiller
This paper considers two challenges faced by practical quantum networks: the bootstrapping of seedless Quantum Random Number Generators (QRNGs) and the resilient combination of Pos…
Continuous variable quantum key distribution channel emulator for the SPOQC mission
Emma Tien Hwai Medlock, Vinod N. Rao, Ry Render +2
In a free space optical (FSO) communication link from satellite to ground, the losses in the channel will be dynamic. Thus, the characterization of the FSO channel is of great impo…
Quantum random number generation from the continuous variable payload for the SPOQC mission
Vinod N. Rao, Killian Murphy, Fadi Ahwal +3
The necessity of random numbers for various tasks, from simulation to cryptography, is crucial and immense. Here we demonstrate CV-QRNG using the CV payload of the SPOQC mission. T…
Continuous Variable Quantum Key Distribution with Single Quadrature Measurement at Arbitrary Reference Frame
Vinod N. Rao, Emma Tien Hwai Medlock, Timothy Spiller +1
We propose a simplified measurement scheme for a Gaussian modulated coherent state (GMCS) protocol for continuous variable quantum key distribution (CV-QKD), utilizing homodyne det…
