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…
