X-entanglement of PDC photon pairs
E. Brambilla, L. Caspani, O. Jedrkiewicz +2
We investigate the spatio-temporal structure of the bi-photon entanglement in parametric down-conversion (PDC) and we demonstrate its non-factorable X-shaped geometry. Such a struc…
Measurement of sub-shot-noise spatial correlations without subtraction of background
Giorgio Brida, Lucia Caspani, Alessandra Gatti +3
In this paper we present the first measurement of sub-shot-noise spatial correlations without any subtraction of background, a result opening the way to realize sub-shot-noise imag…
High-sensitivity imaging with multi-mode twin beams
E. Brambilla, L. Caspani, O. Jedrkiewicz +2
Twin entangled beams produced by single-pass parametric down-conversion (PDC) offer the opportunity to detect weak amount of absorption with an improved sensitivity with respect to…
