Determination of any pure spatial qudits from a minimum number of measurements by phase-stepping interferometry
(American Physical Society, 2017-12)
We present a proof-of-principle demonstration of a method to characterize any pure spatial qudit of arbitrary dimension d, which is based on the classic phase-shift interferometry technique. In the proposed scheme a total ...
Fase topológica fracionária em qudits fotônicos codificados espacialmente
(Universidade Federal de Minas GeraisUFMG, 2014-03-18)
In this work we propose two experimental setups to observe fractional topological phases in qudits. The degree of freedom in which the qudits are encoded is the transverse position of photon pairs generated by spontaneous ...
Manipulação e mapeamento de correlações quânticas em estados de quatro qudits espaciais
(Universidade Federal de Minas GeraisUFMG, 2011-06-13)
During the past thirty years the field of Quantum Information has beenvery successful in proposing protocols and algorithms that involve two-level quantum systems known as qubits. It has been shown that cryptographic keys ...
Controlled generation of mixed spatial qudits with arbitrary degree of purity
(American Physical Society, 2017-09)
We propose a method for preparing mixed quantum states of arbitrary dimension D (D≥2) which are codified in the discretized transverse momentum and position of single photons, once they are sent through an aperture with D ...
