Extremal states for photon number and quadratures as gauges for nonclassicality
Z. Hradil, J. Rehacek, P. de la Hoz +2
Rotated quadratures carry the phase-dependent information of the electromagnetic field, so they are somehow conjugate to the photon number. We analyze this noncanonical pair, findi…
Practical implementation of mutually unbiased bases using quantum circuits
U. Seyfarth, L. L. Sanchez-Soto, G. Leuchs
The number of measurements necessary to perform the quantum state reconstruction of a system of qubits grows exponentially with the number of constituents, creating a major obstacl…
Generation of entangled matter qubits in two opposing parabolic mirrors
N. Trautmann, J. Z. Bernád, M. Sondermann +3
We propose a scheme for the remote preparation of entangled matter qubits in free space. For this purpose, a setup of two opposing parabolic mirrors is considered, each one with a…
Unpolarized states and hidden polarization
P. de la Hoz, G. Bjork, A. B. Klimov +2
We capitalize on a multipolar expansion of the polarisation density matrix, in which multipoles appear as successive moments of the Stokes variables. When all the multipoles up to…
Classical distinguishability as an operational measure of polarization
G. Bjork, H. de Guise, A. B. Klimov +2
We put forward an operational degree of polarization that can be extended in a natural way to fields whose wave fronts are not necessarily planar. This measure appears as a distanc…
Efficient algorithm for optimizing data pattern tomography
L. Motka, B. Stoklasa, J. Rehacek +6
We give a detailed account of an efficient search algorithm for the data pattern tomography proposed by J. Rehacek, D. Mogilevtsev, and Z. Hradil [Phys. Rev. Lett.~\textbf{105}, 01…
