Relative Wavefront Error Correction Over a 2.4 km Free-Space Optical Link via Machine Learning
Nathan K. Long, Benjamin P. Dix-Matthews, Alex Frost +4
In coherent optical communication across turbulent atmospheric channels, reference beacons can be multiplexed with information-encoded signals during transmission. In this case, it…
Enhanced Simultaneous Quantum-Classical Communications Under Composable Security
Nicholas Zaunders, Ziqing Wang, Robert Malaney +2
Simultaneous quantum-classical communications (SQCC) protocols are a family of continuous-variable quantum key distribution (CV-QKD) protocols which allow for quantum and classical…
Quantum Wavefront Correction via Machine Learning for Satellite-to-Earth CV-QKD
Nathan K. Long, Ziqing Wang, Benjamin P. Dix-Matthews +4
State-of-the-art free-space continuous-variable quantum key distribution (CV-QKD) protocols use phase reference pulses to modulate the wavefront of a real local oscillator at the r…
Stokes Parameters and Dual Classical-Quantum Signaling
Anjali Dhiman, Ziqing Wang, Timothy C. Ralph +2
Catering to emerging satellite-based free-space optical (FSO) communication networks and exploiting polarization encoding via Stokes operators, we propose a novel simultaneous quan…
Exploiting Spatial Diversity in Earth-to-Satellite Quantum-Classical Communications
Ziqing Wang, Timothy C. Ralph, Ryan Aguinaldo +1
Despite being an integral part of the vision of quantum Internet, Earth-to-satellite (uplink) quantum communications have been considered more challenging than their satellite-to-E…
