Dispersion of the dielectric permittivity of dense and ultracold atomic gases
Ya. A. Fofanov, A. S. Kuraptsev, I. M. Sokolov +1
On the basis of general theoretical results developed previously in JETP 112, 246 (2011) we analyze the atomic polarization created by weak monochromatic light in an optically thic…
Rephasing processes and quantum memory for light: reversibility issues and how to fix them
Sergey A. Moiseev, J. -L. Le Gouët
Time reversibility is absent from some recently proposed quantum memory protocols such as Absorption Frequency Comb (AFC). Focusing on AFC memory, we show that quantum efficiency a…
Star product and ordered moments of photon creation and annihilation operators
S. N. Filippov, V. I. Man'ko
We develop a star-product scheme of symbols defined by the normally ordered powers of the creation and annihilation photon operators, (a†)^m a^n. The corresponding phase space is a…
Multiple quantum NMR dynamics in a gas of spin-carrying molecules in fluctuating nanopores
E. B. Fel'dman, A. I. Zenchuk
The effect of Gaussian fluctuations of nanopores filled with a gas of spin-carrying molecules () on the multiple quantum (MQ) NMR dynamics is investigated at different varia…
Accuracy features for quantum process tomography using superconductor phase qubits
Yu. I. Bogdanov, S. A. Nuyanzin
We propose a method for precision statistical control of quantum processes based on superconductor phase qubits. Using the universal quantum tomography method, we provide a detaile…
Simulating cyclotron-Bloch dynamics of a charged particle in a 2D lattice by means of cold atoms in driven quasi 1D optical lattices
Andrey R. Kolovsky
Quantum dynamics of a charged particle in a 2D lattice subject to magnetic and electric fields is a rather complicated interplay between cyclotron oscillations (the case of vanishi…
Statistical estimation of the quality of quantum-tomography protocols
Yu. I. Bogdanov, G. Brida, I. D. Bukeev +6
We present a complete methodology for testing the performances of quantum tomography protocols. The theory is validated by several numerical examples and by the comparison with exp…
Asymmetry of bipartite quantum discord
E. B. Fel'dman, A. I. Zenchuk
It is known from the analysis of the density matrix for bipartite systems that the quantum discord (as a measure of quantum correlations) depends on the particular subsystem chosen…
Information capacity of quantum observable
A. S. Holevo
In this paper we consider the classical capacities of quantum-classical channels corresponding to measurement of observables. Special attention is paid to the case of continuous ob…
Measuring microwave quantum states: tomogram and moments
Sergey N. Filippov, Vladimir I. Man'ko
Two measurable characteristics of microwave one-mode photon states are discussed: a rotated quadrature distribution (tomogram) and normally/antinormally ordered moments of photon c…
Rotational Doppler shift of the phase-conjugated photon
A. Yu. Okulov
The rotational Doppler shift of a photon with orbital angular momentum is shown to be an even multiple of the angular frequency of the reference frame rotation…
Microscopic Theory of Scattering of Weak Electromagnetic Radiation by a Dense Ensemble of Ultracold Atoms
I. M. Sokolov, D. V. Kupriyanov, M. D. Havey
Based on the developed quantum microscopic theory, the interaction of weak electromagnetic radiation with dense ultracold atomic clouds is described in detail. The differential and…
Unitary and Non-Unitary Matrices as a Source of Different Bases of Operators Acting on Hilbert Spaces
S. N. Filippov, V. I. Man'ko
Columns of d^2 x N matrices are shown to create different sets of N operators acting on -dimensional Hilbert space. This construction corresponds to a formalism of the star-prod…
Quantum storage via refractive index control
Alexey Kalachev, Olga Kocharovskaya
Off-resonant Raman interaction of a single-photon wave packet and a classical control field in an atomic medium with controlled refractive index is investigated. It is shown that a…
