Transformation of vector beams with radial and azimuthal polarizations in biaxial crystals
Alex Turpin, Asticio Vargas, Angel Lizana +5
We present both experimentally and theoretically the transformation of radially and azimuthally polarized vector beams when they propagate through a biaxial crystal and are transfo…
Experimental characterization of qutrits using SIC-POVMs
Z. E. D. Medendorp, F. A. Torres-Ruiz, L. K. Shalm +3
Generalized quantum measurements (also known as POVMs) are of great importance in quantum information and quantum foundations, but often difficult to perform. We present an experim…
Decoherence in a double-slit quantum eraser
F. A. Torres-Ruiz, G. Lima, A. Delgado +2
We study and experimentally implement a double-slit quantum eraser in the presence of a controlled decoherence mechanism. A two-photon state, produced in a spontaneous parametric d…
Control of quantum interference in the quantum eraser
L Neves, G Lima, J Aguirre +3
We have implemented an optical quantum eraser with the aim of studying this phenomenon in the context of state discrimination. An interfering single photon is entangled with anothe…
Measurement of spatial qubits
G. Lima, F. A. Torres-Ruiz, L. Neves +3
In this paper we study the state determination for composite systems of two spatial qubits. We show, theoretically, that one can use the technique of quantum tomography to reconstr…
Generating mixtures of spatial qubits
G. Lima, F. A. Torres-Ruiz, L. Neves +3
In a recent letter [Phys. Rev. Lett. 94, 100501 (2005)], we presented a scheme for generating pure entangled states of spatial qudits (-dimensional quantum systems) by using the…
