Journal ArticleDOI
Minimum tomography of two entangled qutrits using local measurements of one-qutrit symmetric informationally complete positive operator-valued measure
W. M. Pimenta,B. Marques,Thiago O. Maciel,Reinaldo O. Vianna,Aldo Delgado,Carlos Saavedra,S. Pádua +6 more
TL;DR: In this article, a two-qutrit state is encoded in the transversal paths of a spontaneous parametric down-converted photon pair, and a spatial light modulator allows the necessary 81 POVM elements to reconstruct the state.
Journal ArticleDOI
Experimental simulation of decoherence in photonics qudits.
B. Marques,B. Marques,A. A. Matoso,W. M. Pimenta,A. J. Gutiérrez-Esparza,Marcelo França Santos,S. Pádua +6 more
TL;DR: A well-controlled technique is shown to prepare entangled qudits states as well as to implement dissipative local measurements to realize two specific dynamics: dephasing and amplitude damping of open quantum dynamics.
Journal ArticleDOI
Minimal state tomography of spatial qubits using a spatial light modulator.
W. M. Pimenta,B. Marques,M. A. D. Carvalho,M. R. Barros,J. G. Fonseca,J. Ferraz,M. O. Terra Cunha,S. Pádua +7 more
TL;DR: It is reported that minimal quantum state tomography with spatial qubits created by a pair of parametric down converted twin-photons passing through a double-slit with a novel experimental setup, which includes a Spatial Light Modulator, is reported.
Journal ArticleDOI
Detection of nonlocal superpositions
A. J. Gutiérrez-Esparza,W. M. Pimenta,B. Marques,B. Marques,A. A. Matoso,Jan Sperling,Werner Vogel,S. Pádua +7 more
TL;DR: The verification of the Schmidt number of quantum correlated radiation fields has been studied in this article, which counts the number of global superpositions of product states which are needed to describe a compound quantum system.
Journal ArticleDOI
Classical imaging with undetected light
A. C. Cardoso,L. P. Berruezo,D. F. Ávila,Gabriela Barreto Lemos,W. M. Pimenta,Carlos H. Monken,Pablo L. Saldanha,S. Pádua +7 more
TL;DR: In this article, a double passage of a pump and a signal laser beam through a nonlinear crystal was used to obtain phase and intensity images of an object by detecting classical light which never interacted with it.
