All-photonic quantum key distribution beyond the single-repeater bound
Matthew S. Winnel, Sergio Juárez, Chithrabhanu Perumangatt +2
Quantum protocols require classical signaling, and when classical signals propagate faster than quantum ones, standard rate-loss limits can be surpassed. We introduce an all-photon…
Towards Fully Passive Time-Bin Quantum Key Distribution over Moving Free-Space Channels
Ramy Tannous, Wilson Wu, Stéphane Vinet +4
Encoding quantum information in photonic time-bin states is typically considered impractical for moving free-space quantum communication due to the difficulties with phase stabiliz…
Polarization-orbital angular momentum duality assisted entanglement observation for indistinguishable photons
Nijil Lal, Sarika Mishra, Anju Rani +3
Duality in the entanglement of identical particles manifests that entanglement in only one variable can be revealed at a time. We demonstrate this using polarization and orbital an…
Realizing quantum nodes in space for cost-effective, global quantum communication: in-orbit results and next steps
Chithrabhanu Perumangatt, Tom Vergoossen, Alexander Lohrmann +6
Quantum sources and receivers operating on-board satellites are an essential building block for global quantumnetworks. SpooQy-1 is a satellite developed at the Centre for Quantum…
Entangled Photon-Pair Sources based on three-wave mixing in bulk crystals
Ali Anwar, Chithrabhanu Perumangatt, Fabian Steinlechner +2
Entangled photon-pairs are a critical resource in quantum communication protocols ranging from quantum key distribution to teleportation. The current workhorse technique for produc…
Entanglement demonstration on board a nano-satellite
Aitor Villar, Alexander Lohrmann, Xueliang Bai +14
Global quantum networks for secure communication can be realised using large fleets of satellites distributing entangled photon-pairs between ground-based nodes. Because the cost o…
