Waveguide-based OPO source of entangled photon pairs (2009)
Pomarico, Enrico, Sanguinetti, Bruno, Gisin, Nicolas, Thew, Robert, Zbinden, Hugo, Schreiber, Gerhard, ...
In this paper we present a compact source of narrow-band energy-time entangled photon pairs in the telecom regime based on a Ti-indiffused Periodically Poled Lithium Niobate (PPLN) waveguide...
One-way quantum computation with two-photon multiqubit cluster states (2008)
Vallone, Giuseppe, Pomarico, Enrico, De Martini, Francesco, Mataloni, Paolo
We describe in detail the application of four qubit cluster states, built on the simultaneous entanglement of two photons in the degrees of freedom of polarization and linear momentum, for the...
Active one-way quantum computation with 2-photon 4-qubit cluster states (2007)
Vallone, Giuseppe, Pomarico, Enrico, De Martini, Francesco, Mataloni, Paolo
By using 2-photon 4-qubit cluster states we demonstrate deterministic one-way quantum computation in single qubit rotation algorithm. In this operation feed-forward measurements are automatically...
Experimental Realization of Polarization Qutrits from Non-Maximally Entangled States (2007)
Vallone, Giuseppe, Pomarico, Enrico, Mataloni, Paolo, De Martini, Francesco, Barbieri, Marco
Based on a recent proposal [Phys. Rev. A 71, 062337 (2005)], we have experimentally realized two photon polarization qutrits by using non-maximally entangled states and linear optical...
Vallone, Giuseppe, Pomarico, Enrico, De Martini, Francesco, Mataloni, Paolo
Four-qubit cluster states of two photons entangled in polarization and linear momentum have been used to realize a complete set of single qubit rotations and the C-NOT gate for equatorial qubits with...
Realization and characterization of a 2-photon 4-qubit linear cluster state (2007)
Vallone, Giuseppe, Pomarico, Enrico, Mataloni, Paolo, De Martini, Francesco, Berardi, Vincenzo
We report on the experimental realization of a 4-qubit linear cluster state via two photons entangled both in polarization and linear momentum. This state was investigated by performing tomographic...
