Programmable entanglement oscillations in a non-Markovian channel / S. Cialdi, D. Brivio, E. Tesio, M. G. A. Paris.. - In: PHYSICAL REVIEW A. - ISSN 1050-2947. - 83:4(2011), pp. 042308.042308.1-042308.042308.5.
Abstract:
We suggest and demonstrate an all-optical experimental setup to observe and engineer entanglement oscillations
of a pair of polarization qubits in an effective non-Markovian channel. We generate entangled photon pairs by
spontaneous parametric down-conversion (SPDC), and then insert a programmable spatial light modulator in
order to impose a polarization-dependent phase shift on the spatial domain of the SPDC output. This creates an
effective programmable non-Markovian environment where modulation of the environment spectrum is obtained
by inserting a spatial grating on the signal arm. In our experiment, programmable oscillations of entanglement
are achieved, where the entangled state obtained at the maximum of the revival after sudden death violates Bell’s
inequality by 17 standard deviations
