Opportunistic QKD: Exploiting Idle Capacity of Classical WDM Systems
Sumit Chaudhary, Pere Munar Vallespir, Alonso Viladomat Jasso +1
While QKD has been proven in lab environments, large-scale implementation requires integration with existing infrastructure. This paper proposes an opportunistic QKD framework that…
End-to-End QKD Using LEO Satellite Networks
Sumit Chaudhary, Baqir Kazmi, Janis Nötzel
We propose a satellite-based Quantum Key Distribution (QKD) network that enables global-scale, end-to-end secure key exchange without relying on trusted intermediate nodes. The net…
Distance-Security Tradeoffs for Repeaterless End-to-End QKD Networks
Sumit Chaudhary, Davide Li Calsi, JinHyeock Choi +2
Quantum Key Distribution (QKD) offers provably secure, information-theoretic key exchange, but in long-distance scenarios without quantum repeaters, Trusted Nodes (TNs) are commonl…
Robustness of WDM technique for the co-propagation of quantum with classical signals in an optical fiber
Sumit Chaudhary, Shahram Dehdashti, Igor Litvin +1
Many quantum communication systems operate based on weak light pulses which by design are assumed to operate in isolation from regular data traffic. With the widespread availabilit…
Quantum-enhanced photocell based on GaN quantum dots
Aditya Dev, Sumit Chaudhary, Jay Reshamiya +2
In this work, we propose an efficient quantum-enhanced solid-state photocell based on GaN quantum dots. We exploit the strong built-in electric field in GaN QDs and excitonic dipol…
A novel graph-based formulation for characterizing morphology with application to organic solar cells
Olga Wodo, Srikanta Tirthapura, Sumit Chaudhary +1
Organic solar cells have the potential for widespread usage due to their promise of low cost, roll-to-roll manufacturability, and mechanical flexibility. However, deployment is imp…
