Orbital angular momentum from marginals of quadrature distributions
L. L. Sanchez-Soto, A. B. Klimov, P. de la Hoz +4
We set forth a method to analyze the orbital angular momentum of a light field. Instead of using the canonical formalism for the conjugate pair angle-angular momentum, we model thi…
Quantum polarization tomography of bright squeezed light
C. R. Muller, B. Stoklasa, C. Gabriel +7
We reconstruct the polarization sector of a bright polarization squeezed beam starting from a complete set of Stokes measurements. Given the symmetry that underlies the polarizatio…
Interaction of highly focused vector beams with a metal knife-edge
P. Marchenko, S. Orlov, C. Huber +4
We investigate the interaction of highly focused linearly polarized optical beams with a metal knife-edge both theoretically and experimentally. A high numerical aperture objective…
Sizing up entanglement in mutually unbiased bases with Fisher information
J. Rehacek, Z. Hradil, A. B. Klimov +2
An efficient method for assessing the quality of quantum state tomography is developed. Special attention is paid to the tomography of multipartite systems in terms of unbiased mea…
A pulsed source of continuous variable polarization entanglement
O. Glöckl, J. Heersink, N. Korolkova +2
We have experimentally demonstrated polarization entanglement using continuous variables in an ultra-short pulsed laser system at telecommunication wavelengths. Exploiting the Kerr…
Fundamental quantum limits in ellipsometry
L. Rudnicki, L. L. Sanchez-Soto, G. Leuchs +1
We establish the ultimate limits that quantum theory imposes on the accuracy attainable in optical ellipsometry. We show that the standard quantum limit, as usual reached when the…
