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…
Unambiguous modification of nonorthogonal single and two photon polarization states
F. A. Torres-Ruiz, J. Aguirre, A. Delgado +5
In this work we propose a probabilistic method which allows an unambiguous modification of two non-orthogonal quantum states. We experimentally implement this protocol by using two…
