Combined Quantum and Post-Quantum Security Performance Under Finite Keys
Aman Gupta, Ravi Singh Adhikari, Anju Rani +2
Recent advances in quantum-secure communication have highlighted the value of hybrid schemes that combine Quantum Key Distribution (QKD) with Post-Quantum Cryptography (PQC). Yet m…
A New Quantum Secure Time Transfer System
Ravi Singh Adhikari, Aman Gupta, Anju Rani +2
High-precision clock synchronization is essential for a wide range of network-distributed applications. In the quantum space, these applications include communication, sensing, and…
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…
Relative Wavefront Errors in Continuous-Variable Quantum Communication
Nathan K. Long, John Wallis, Alex Frost +4
When undertaking continuous-variable quantum key distribution (CV-QKD) across atmospheric channels, strong classical local oscillators (LOs) are often polarization-multiplexed with…
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…
Obfuscated Quantum and Post-Quantum Cryptography
Anju Rani, Xiaoyu Ai, Aman Gupta +2
In this work, we present an experimental deployment of a new design for combined quantum key distribution (QKD) and post-quantum cryptography (PQC). Novel to our system is the dyna…
