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
The paper characterizes how loss varies in a satellite‑to‑ground channel for continuous‑variable quantum key distribution, considering factors like zenith angle, turbulence, and wa…
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…
Energy efficient optical tracking for space quantum communication
Eric Vokes, Vinod N. Rao, Elinore Spencer +1
Power consumption is a critical constraint for CubeSat based quantum communication, where tracking systems often dominate the onboard power budget. We demonstrate an energy-efficie…
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…
Phase noise characterisation of a 2-km Hollow-Core Nested Antiresonant Nodeless Fibre for Twin-Field Quantum Key Distribution
Mariella Minder, Sophie Albosh, Obada Alia +5
The performance of quantum key distribution (QKD) is heavily dependent on the physical properties of the channel over which it is executed. Propagation losses and perturbations in…
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…
