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…
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…
