Active one-way quantum computation with 2-photon 4-qubit cluster states
Giuseppe Vallone, Enrico Pomarico, Francesco De Martini +1
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 ar…
Quantum state decorrelation
Giacomo M. D'Ariano, Rafal Demkowicz-Dobrzanski, Paolo Perinotti +1
We address the general problem of removing correlations from quantum states while preserving local quantum information as much as possible. We provide a complete solution in the ca…
Experimental macroscopic coherence by phase-covariant cloning of a single photon
Eleonora Nagali, Tiziano De Angelis, Fabio Sciarrino +1
We investigate the multiphoton states generated by high-gain optical parametric amplification of a single injected photon, polarization encoded as a ''qubit''. The experiment confi…
Experimental Realization of Polarization Qutrits from Non-Maximally Entangled States
Giuseppe Vallone, Enrico Pomarico, Paolo Mataloni +2
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 opti…
Intensity correlations, entanglement properties and ghost imaging in multimode thermal-seeded parametric downconversion: Theory
Ivo P. Degiovanni, Maria Bondani, Emiliano Puddu +2
We address parametric-downconversion seeded by multimode pseudo-thermal fields. We show that this process may be used to generate multimode pairwise correlated states with entangle…
Experimental test of the no signaling theorem
Tiziano De Angelis, Francesco De Martini, Eleonora Nagali +1
In 1981 N. Herbert proposed a gedanken experiment in order to achieve by the ''First Laser Amplified Superluminal Hookup'' (FLASH) a faster than light communication (FTL) by quantu…
Phase-covariant cloning of coherent states
Massimiliano F. Sacchi
We consider the problem of phase-covariant cloning for coherent states. We show that an experimental scheme based on ideal phase measurement and feedforward outperforms the semicla…
Realization and characterization of a 2-photon 4-qubit linear cluster state
Giuseppe Vallone, Enrico Pomarico, Paolo Mataloni +2
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 perfo…
Erasable and unerasable correlations
G. M. D'Ariano, R. Demkowicz-Dobrzanski, P. Perinotti +1
We address the problem of removing correlation from sets of states while preserving as much local quantum information as possible. We prove that states obtained from universal clon…
How continuous quantum measurements in finite dimension are actually discrete
G. Chiribella, G. M. D'Ariano, D. M. Schlingemann
We show that in finite dimension a quantum measurement with continuous set of outcomes is always equivalent to a continuous random choice of measurements with only finite outcomes.
