Maximally polarized states for quantum light fields
L. L. Sanchez-Soto, E. C. Yustas, G. Bjork +1
The degree of polarization of a quantum state can be defined as its Hilbert-Schmidt distance to the set of unpolarized states. We demonstrate that the states optimizing this degree…
Path Integral Approach for Superintegrable Potentials on Spaces of Non-constant Curvature: II. Darboux Spaces DIII and DIV
Christian Grosche, George Pogosyan, Alexei Sissakian
This is the second paper on the path integral approach of superintegrable systems on Darboux spaces, spaces of non-constant curvature. We analyze in the spaces $\DIII$ and $\DIV$ f…
Mutually unbiased bases and discrete Wigner functions
Gunnar Bjork, Jose L. Romero, Andrei B. Klimov +1
Mutually unbiased bases and discrete Wigner functions are closely, but not uniquely related. Such a connection becomes more interesting when the Hilbert space has a dimension that…
Path Integral Approach for Superintegrable Potentials on Spaces of Non-constant Curvature: I. Darboux Spaces DI and DII
Christian Grosche, George S. Pogosyan, Alexei N. Sissakian
In this paper the Feynman path integral technique is applied for superintegrable potentials on two-dimensional spaces of non-constant curvature: these spaces are Darboux spaces D_I…
Asymmetrical two-atom entanglement in a coated microsphere
G. Burlak, A. Klimov
We study evolution of entanglement of two two-level atoms placed inside a multilayered microsphere. We show that due to inhomogeneity of the field modes this entanglement essential…
