Symplectic tomographic probability distribution of crystallized Schrödinger cat states
Julio A. López-Saldívar, Vladimir I. Man'ko, Margarita A. Man'ko
Within the framework of the probability representation of quantum mechanics, we study a superposition of generic Gaussian states associated to symmetries of a regular polygon of n…
Differential Parametric Formalism for the Evolution of Gaussian States: Nonunitary Evolution and Invariant States
Julio A. López-Saldívar, Margarita A. Man'ko, Vladimir I. Man'ko
In a differential approach elaborated, we study the evolution of the parameters of Gaussian, mixed, continuous variable density matrices, whose dynamics are given by Hermitian Hami…
Star Product Formalism for Probability and Mean Value Representations of Qudits
Peter Adam, Vladimir A. Andreev, Margarita A. Man'ko +2
The quantizer-dequantizer formalism is developed for mean value and probability representation of qubits and qutrits. We derive the star-product kernels providing the possibility t…
Dynamics of a harmonic oscillator coupled with a Glauber amplifier
R. Grimaudo, V. I. Man'ko, M. A. Man'ko +1
A system of a quantum harmonic oscillator bi-linearly coupled with a Glauber amplifier is analysed considering a time-dependent Hamiltonian model. The Hilbert space of this system…
A New Mechanism of Open System Evolution and Its Entropy Using Unitary Transformations in Noncomposite Qudit Systems
Julio A. López-Saldívar, Octavio Castaños, Margarita A. Man'ko +1
The evolution of an open system is usually associated with the interaction of the system with an environment. A new method to study the open-type system evolution of a qubit (two-l…
Qubit representation of qudit states: correlations and state reconstruction
Julio A. López-Saldívar, Octavio Castaños, Margarita A. Man'ko +1
A method to establish a qubit decomposition of a general qudit state is presented. This new representation allows a geometrical depiction of any qudit state in the Bloch sphere. Ad…
