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…
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…
Experimental conversion of position correlation into polarization entanglement
Chithrabhanu Perumangatt, Alexander Lohrmann, Alexander Ling
This manuscript presents a method to convert position correlation of photon-pairs into polarization entanglement. This is achieved by individually manipulating the polarization sta…
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…
Observing sub-Poissonian statistics of twisted single photons using oscilloscope
Nijil Lal, Biveen Shajilal, Ali Anwar +2
Heralded single photon sources (HSPS) from spontaneous parametric down-conversion are widely used as single photon sources. We study the photon number statistics of an HSPS carryin…
Experimental comparison of tomography and self-testing in certifying entanglement
Koon Tong Goh, Chithrabhanu Perumangatt, Zhi Xian Lee +2
We assess the quality of a source of allegedly pure two-qubit states using both standard tomography and methods inspired by device-independent self-testing. Even when the detection…
