Numerical security framework for quantum key distribution with bypass channels
Lewis Wooltorton, Twesh Upadhyaya, Mohsen Razavi
Satellite based quantum key distribution (QKD) aims to establish secure key exchange over long distances despite significant technological challenges. To alleviate some of these ch…
Analytical bounds for decoy-state quantum key distribution with discrete phase randomization
Zhaohui Liu, Ahmed Lawey, Mohsen Razavi
We analyze the performance of quantum key distribution (QKD) protocols that rely on discrete phase randomization (DPR). For many QKD protocols that rely on weak coherent pulses (WC…
Combatting noise in near-term quantum data centres
Kenny Campbell, Ahmed Lawey, Mohsen Razavi
We analyse the performance of different error handling methods in the quantum data centre paradigm of distributed quantum computing. We compare the impact of quantum error detectio…
Quantum Data Centers in the Presence of Noise
K. Campbell, A. Lawey, M. Razavi
Quantum data centres (QDCs) could overcome the scalability challenges of modern quantum computers. Single-processor monolithic quantum computers are affected by increased cross tal…
