Six-qubit two-photon hyperentangled cluster states: characterization and application to quantum computation
Giuseppe Vallone, Gaia Donati, Raino Ceccarelli +1
Six-qubit cluster states built on the simultaneous entanglement of two photons in three independent degrees of freedom, i.e. polarization and a double longitudinal momentum, have b…
Experimental Entanglement and Nonlocality of a Two-Photon Six-Qubit Cluster State
Raino Ceccarelli, Giuseppe Vallone, Francesco De Martini +2
We create a six-qubit linear cluster state by transforming a two-photon hyperentangled state in which three qubits are encoded in each particle, one in the polarization and two in…
Hyperentanglement of two photons in three degrees of freedom
G. Vallone, R. Ceccarelli, F. De Martini +1
A 6-qubit hyperentangled state has been realized by entangling two photons in three degrees of freedom. These correspond to the polarization, the longitudinal momentum and the indi…
Hyperentanglement witness
Giuseppe Vallone, Raino Ceccarelli, Francesco De Martini +1
A new criterium to detect the entanglement present in a {\it hyperentangled state}, based on the evaluation of an entanglement witness, is presented. We show how some witnesses rec…
