Quantum strong subadditivity condition for systems without subsystems
Margarita A Man'ko, Vladimir I Man'ko
The strong subadditivity condition for the density matrix of a quantum system, which does not contain subsystems, is derived using the qudit-portrait method. An example of the qudi…
Wigner functions and spin tomograms for qubit states
Peter Adam, Vladimir A. Andreev, Iulia Ghiu +3
We establish the relation of the spin tomogram to the Wigner function on a discrete phase space of qubits. We use the quantizers and dequantizers of the spin tomographic star-produ…
Quantum Reflection of Antihydrogen in the GBAR Experiment
Gabriel Dufour, Romain Guérout, Astrid Lambrecht +3
In the GBAR experiment, cold antihydrogen atoms will be left to fall on an annihilation plate with the aim of measuring the gravitational acceleration of antimatter. Here, we study…
Shaping the distribution of vertical velocities of antihydrogen in GBAR
Gabriel Dufour, Pascal Debu, Astrid Lambrecht +3
GBAR is a project aiming at measuring the free fall acceleration of gravity for antimatter, namely antihydrogen atoms (). Precision of this timing experiment…
Measurement of the 5D Level Polarizabilty in Laser Cooled Rb atoms
S. Snigirev, A. Golovizin, D. Tregubov +5
We report on accurate measurements of the scalar and tensor polarizabilities of the 5D fine structure levels 5D3/2 and 5D5/2 in Rb. The measured values show reasonable corresponden…
Inequalities for nonnegative numbers and information properties
Margarita A. Man'ko, Vladimir I. Man'ko
We discuss some inequalities for N nonnegative numbers. We use these inequalities to obtain known inequalities for probability distributions and new entropic and information inequa…
Tomographic Discord and Quantum Correlations for System of Qubits
V. I. Manko, Anatoli Yurkevich
The difference of quantum mutual information for bipartite system of qubits and minimum taken with respect to local unitary transformation group is introduced as a characteristic o…
Generalized qubit portrait of the qutrit state density matrix
V. N. Chernega, O. V. Man'ko, V. I. Man'ko
New inequalities for tomographic probability distributions and density matrices of qutrit states are obtained by means of generalization of qubit portrait method. The approach base…
Hermite Polynomial Representation of the Spin States
Dmitry B. Lemeshevskiy, Vladimir I. Man'ko
The invertable map of spin state density operator onto quasiprobability distribution of three continuous variables is constructed. The connection with two-mode electromagnetic fiel…
Stochastic evolution of finite level systems: classical vs. quantum
D. Chruściński, V. I. Man'ko, G. Marmo +1
Quantum dynamics of the density operator in the framework of a single probability vector is analyzed. In this framework quantum states define a proper convex quantum subset in an a…
Single photon-added coherent states: estimation of parameters and fidelity of the optical homodyne detection
S. N. Filippov, V. I. Man'ko, A. S. Coelho +2
Travelling modes of single-photon-added coherent states (SPACS) are characterized via optical homodyne tomography. Given a set of experimentally measured quadrature distributions,…
