Terrestrial readiness campaign for space-to-ground quantum communications with a space-qualified entangled photon-pair system
Gianluca De Santis, Jia Boon Chin, Srihari Sivasankaran +8
Realizing a global quantum internet relies on the deployment of robust satellite-based entanglement distribution links. While pioneering demonstrations have established the feasibi…
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…
Broadband pumped polarization entangled photon-pair source in a linear beam displacement interferometer
Alexander Lohrmann, Chithrabhanu Perumangatt, Aitor Villar +1
We experimentally demonstrate a source of polarization entangled photon-pairs based on a single periodically-poled potassium titanyl phosphate (PPKTP) crystal pumped with a broadba…
Generating entangled photon pairs in a parallel crystal geometry
Alexander Lohrmann, Aitor Villar, Alexander Ling
We present recent findings towards developing brighter entangled photon sources in critically phase matched (CPM) nonlinear crystals. Specifically, we use type-I collinear phase ma…
High fidelity field stop collection for polarization-entangled photon pair sources
Alexander Lohrmann, Aitor Villar, Arian Stolk +1
We present an experimental demonstration of a bright and high fidelity polarization entangled photon pair source. The source is constructed using two critically phase matched -B…
Experimental entangled photon pair generation using crystals with parallel optical axes
Aitor Villar, Alexander Lohrmann, Alexander Ling
We present an optical design where polarization-entangled photon pairs are generated within two -Barium Borate crystals whose optical axes are parallel. This design increases th…
