Designing a Satellite Serviced Quantum Network Backbone for Concurrent Global Connectivity

Prateek Mantri, Stav Haldar, Albert Williams +1

Satellite-serviced quantum networks pose an architectural problem distinct from classical satellite networking: because entanglement cannot be copied, and long-lived buffering is t…

Probabilistic Cutoffs in Homogeneous Quantum Repeater Chains

Jeroen Grimbergen, Stav Haldar, Alvaro Gomez Inesta +1

We study quantum repeater chains in which entangled links between neighbouring nodes are created through heralded entanglement generation and adjacent links are swapped as soon as…

Efficient formulation of quantum network under amplitude damping noise: Highlighting benefits over its Pauli-twirled counterpart

Sudipta Mondal, Pritam Halder, Stav Haldar +1

At the heart of building a large-scale quantum internet lies the challenge of establishing long-distance entanglement using quantum repeaters, which mitigate direct transmission lo…

Reducing classical communication costs in multiplexed quantum repeaters using hardware-aware quasi-local policies

Stav Haldar, Pratik J. Barge, Xiang Cheng +5

Future quantum networks will have nodes equipped with multiple quantum memories, allowing for multiplexing and entanglement distillation strategies in order to increase fidelities…

Bell's shadows from satellites

Stav Haldar, Rachel L. McDonald, Sage Ducoing +1

Establishing reliable quantum links between a network of satellites and ground stations is a crucial step towards realizing a wide range of satellite-based quantum protocols, inclu…
