Double-slit implementation of minimal Deutsch algorithm
B. Marques, M. R. Barros, W. M. Pimenta +5
We report an experimental implementation of the minimal Deutsch algorithm in an optical setting. In this version, a redundancy is removed from the most famous form of the algorithm…
Protection of quantum information and optimal singlet conversion through higher dimensional quantum systems and environment monitoring
E. Mascarenhas, B. Marques, D. Cavalcanti +2
We study how to protect quantum information in quantum systems subjected to local dissipation. We show that combining the use of three-level systems, environment monitoring, and lo…
Minimum tomography of two entangled qutrits using local measurements of one-qutrit SIC-POVM
W. M. Pimenta, B. Marques, T. O. Maciel +4
An experimental demonstration of two-qutrit state tomography via one-qutrit symmetric informationally complete positive operator-valued measure (SIC-POVM) is presented. A two-qutri…
An unconditional experimental test of Nonclassicality
A. Hameedi, B. Marques, P. Mironowicz +3
We theoretically introduce and experimentally demonstrate the realization of a nonclassicality test that allows for arbitrarily low detection efficiency without invoking any extra…
Experimental observation of fractional topological phases with photonic qudits
A. A. Matoso, X. Sánchez-Lozano, W. M. Pimenta +6
Geometrical and topological phases play a fundamental role in quantum theory. Geometric phases have been proposed as a tool for implementing unitary gates for quantum computation.…
Experimental simulation of decoherence in photonics qudits
B. Marques, A. A. Matoso, W. M. Pimenta +3
We experimentally perform the simulation of open quantum dynamics in single-qudit systems. Using a spatial light modulator as a dissipative optical device, we implement dissipative…
