Eliminating Spectral Distinguishability in Ultrafast Spontaneous Parametric Down-conversion
Hou Shun Poh, Jiaqing Lim, Ivan Marcikic +2
Generation of polarization-entangled photon pairs with a precise timing through down-conversion of femtosecond pulses is often faced with a degraded polarization entanglement quali…
Experimental quantum key distribution based on a Bell test
Alexander Ling, Matthew P. Peloso, Ivan Marcikic +3
We report on a complete free-space field implementation of a modified Ekert91 protocol for quantum key distribution using entangled photon pairs. For each photon pair we perform a…
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…
Long distance entanglement swapping with photons from separated sources
H. de Riedmatten, I. Marcikic, J. A. W. van Houwelingen +3
We report the first experimental realization of entanglement swapping over large distances in optical fibers. Two photons separated by more than two km of optical fibers are entang…
Four-photon correction in two-photon Bell experiments
Valerio Scarani, Hugues de Riedmatten, Ivan Marcikic +2
Correlated photons produced by spontaneous parametric down-conversion are an essential tool for quantum communication, especially suited for long-distance connections. To have a re…
