Perfect antireflection via negative refraction
J. J. Monzon, A. G. Barriuso, L. L. Sanchez-Soto
We suggest a geometrical framework to discuss the action of slabs of negatively refracting materials. We show that these slabs generate the same orbits as normal materials, but tra…
On the structure of the sets of mutually unbiased bases for N qubits
J. L. Romero, G. Bjork, A. B. Klimov +1
For a system of N qubits, spanning a Hilbert space of dimension d=2^N, it is known that there exists d+1 mutually unbiased bases. Different construction algorithms exist, and it is…
Geometrical aspects of first-order optical systems
A. G. Barriuso, J. J. Monzon, L. L. Sanchez-Soto +1
We reconsider the basic properties of ray-transfer matrices for first-order optical systems from a geometrical viewpoint. In the paraxial regime of scalar wave optics, there is a w…
Quantum phase-space description of light polarization
A. B. Klimov, J. Delgado, L. L. Sanchez-Soto
We present a method to characterize the polarization state of a light field in the continuous-variable regime. Instead of using the abstract formalism of SU(2) quasidistributions,…
Distance-based degrees of polarization for a quantum field
A. B. Klimov, L. L. Sanchez-Soto, E. C. Yustas +2
It is well established that unpolarized light is invariant with respect to any SU(2) polarization transformation. This requirement fully characterizes the set of density matrices r…
Comparing omnidirectional reflection from periodic and quasiperiodic one-dimensional photonic crystals
A. G. Barriuso, J. J. Monzon, L. L. Sanchez-Soto +1
We determine the range of thicknesses and refractive indices for which omnidirectional reflection from quasiperiodic multilayers occurs. By resorting to the notion of area under th…
