Tomography of multimode quantum systems with quadratic Hamiltonians and multivariable Hermite polynomials
V. I. Man'ko, V. A. Sharapov, E. V. Shchukin
The systems with multimode nonstationary Hamiltonians quadratic in position and momentum operators are reviewed. The tomographic probability distributions (tomograms) for the Fock…
Classical and Quantum-like approaches to Charged-Particle Fluids in a Quadrupole
S. De Nicola, R. Fedele, V. I. Man'ko
A classical description of the dynamics of a dissipative charged-particle fluid in a quadrupole-like device is developed. It is shown that the set of the classical fluid equations…
Tomographic map within the framework of star-product quantization
Olga V. Man'ko, Vladimir I. Man'ko, Giuseppe Marmo
Tomograms introduced for the description of quantum states in terms of probability distributions are shown to be related to a standard star-product quantization with appropriate ke…
Alternative commutation relations, star products and tomography
Olga V. Man'ko, V. I. Man'ko, G. Marmo
Invertible maps from operators of quantum obvservables onto functions of c-number arguments and their associative products are first assessed. Different types of maps like Weyl-Wig…
Polynomial Lie algebra methods in solving the second-harmonic generation model: some exact and approximate calculations
V. P. Karassiov, A. A. Gusev, S. I. Vinitsky
We compare exact and SU(2)-cluster approximate calculation schemes to determine dynamics of the second-harmonic generation model using its reformulation in terms of a polynomial Li…
Deformed versus undeformed cat states encoding qubit
Stefano Mancini, Vladimir I. Man'ko
We study the possibility of exploiting superpositions of coherent states to encode qubit. A comparison between the use of deformed and undeformed bosonic algebra is made in connect…
An implementation of the polynomial Lie algebra methods for solving a class of nonlinear models in quantum optics
V. P. Karassiov, A. A. Gusev, S. I. Vinitsky
We develop some calculation schemes to determine dynamics of a wide class of integrable quantum-optical models using their symmetry adapted reformulation in terms of polynomial Lie…
Quantum computation by quantum-like systems
M. A. Man'ko, V. I. Man'ko, R. Vilela Mendes
Using a quantumlike description for light propagation in nonhomogeneous optical fibers, quantum information processing can be implemented by optical means. Quantum-like bits (qulbi…
The survival of quantum coherence in deformed states superposition
Stefano Mancini, Vladimir I. Man'ko
We study the dissipative dynamics of deformed coherent states superposition. We find that such kind of superposition can be more robust against decoherence than the usual Schroding…
Quasiprobability and Probability Distributions for Spin 1/2 States
M. O. Terra Cunha, V. I. Man'ko, M. O. Scully
We develop a Radon like transformation, in which quasiprobability distribution for spin 1/2 states is written in terms the tomographic probability distribution .
