Experimental demonstration of four-party quantum secret sharing
S. Gaertner, C. Kurtsiefer, M. Bourennane +1
Secret sharing is a multiparty cryptographic task in which some secret information is splitted into several pieces which are distributed among the participants such that only an au…
Joint Spectrum Mapping of Polarization Entanglement in Spontaneous Parametric Down-conversion
Hou Shun Poh, Chune Yang Lum, Ivan Marcikic +2
Polarization-entangled photon pairs can be efficiently prepared into pure Bell states with a high fidelity via type-II spontaneous parametric down-conversion (SPDC) of narrow-band…
Free-space quantum key distribution with entangled photons
Ivan Marcikic, Antia Lamas-Linares, Christian Kurtsiefer
We report on a complete experimental implementation of a quantum key distribution protocol through a free space link using polarization-entangled photon pairs from a compact parame…
Experimental Polarization State Tomography using Optimal Polarimeters
Alexander Ling, Soh Kee Pang, Antia Lamas-Linares +1
We report on the experimental implementation of a polarimeter based on a scheme known to be optimal for obtaining the polarization vector of ensembles of spin-1/2 quantum systems,…
