Non-Markovian delay-assisted sensing with waveguide-coupled quantum emitters
Prajit Dhara, Isack Padilla, Saikat Guha +2
We show that in a minimal setup of two waveguide-coupled quantum emitters, separated by long distances and subject to an external field, time-delayed feedback can be a resource for…
Optimum-Transmission Free-Space Optical Communications
Prajit Dhara, Babak N. Saif, Jeffrey H. Shapiro +1
Slepian developed the Prolate Spheroidal Wavefunction (PSW) spatial-mode basis, which forms the normal modes of the Fresnel-propagation kernel of a free-space optical communication…
Full-stack Physics-level model of cascaded entanglement links
J. Gabriel Richardson, Prajit Dhara, Abhishek Bhatt +2
While the last few decades have seen a proliferation of experimental demonstrations of entanglement sources, practicality of deployment has been a secondary concern. Recently, the…
Scheduling in Quantum Satellite Networks: Fairness and Performance Optimization
Ashutosh Jayant Dikshit, Naga Lakshmi Anipeddi, Prajit Dhara +5
Quantum satellite networks offer a promising solution for achieving long-distance quantum communication by enabling entanglement distribution across global scales. This work formul…
Coherent State Assisted Entanglement Generation Between Quantum Memories
Chaohan Cui, Prajit Dhara, Saikat Guha
Generating entanglement deterministically at a capacity-approaching rate is critical for next-generation quantum networks. We propose weak-coherent-state-assisted protocols that ca…
Blockwise Post-processing in Satellite-based Quantum Key Distribution
Minu J. Bae, Nitish K. Panigrahy, Prajit Dhara +5
Free-space satellite communication has significantly lower photon loss than terrestrial communication via optical fibers. Satellite-based quantum key distribution (QKD) leverages t…
