Optical integration of a real-valued function by measurement of a Stokes Parameter
Gabriela Barreto Lemos, Paulo Henrique Souto Ribeiro, Stephen Walborn
We experimentally implement an optical algorithm for integration of a real-valued bivariate func- tion. A user-defined function is encoded in the position-dependent phase of one of…
Characterization of a spatial light modulator as a polarization quantum channel
G. Barreto Lemos, J. O. de Almeida, S. P. Walborn +2
Spatial light modulators are versatile devices employed in a vast range of applications to modify the transverse phase or amplitude profile of an incident light beam. Most experime…
Ancilla-assisted measurement of photonic spatial correlations and entanglement
M. Hor-Meyll, J. O. de Almeida, G. B. Lemos +2
We report an experiment in which the moments of spatial coordinates of down-converted photons are measured directly, without having to reconstruct any marginal probability distribu…
Quantum Imaging with Undetected Photons
Gabriela B. Lemos, Victoria Borish, Garrett D. Cole +3
Indistinguishable quantum states interfere, but the mere possibility of obtaining information that could distinguish between overlapping states inhibits quantum interference. Quant…
