Towards Schrödinger Cat States in the Second Harmonic Generation
Ranjit Singh, Leonid A. Barinov, Grigori G. Amosov +1
We investigate the quantum evolution of the pump field in second-harmonic generation under strong pump depletion. Starting from a coherent state, the pump develops a nonclassical p…
On characteristics of mixed unitary channels being additive or multiplicative with respect to taking tensor products
Grigori Amosov
We study mixed unitary channels generated by finite subgroups of the group of all unitary operators in a Hilbert space. Based on the majorization theory we introduce techniques all…
On reconstruction of states from evolution induced by quantum dynamical semigroups perturbed by covariant measures
Grigori Amosov, Egor Baitenov, Alexander Pechen
In this work, we show the ability to restore states of quantum systems from evolution induced by quantum dynamical semigroups perturbed by covariant measures. Our procedure describ…
On errors generated by unitary dynamics of bipartite quantum systems
G. G. Amosov, A. S. Mokeev
Given a quantum channel it is possible to define the non-commutative operator graph whose properties determine a possibility of error-free transmission of information via this chan…
On non-commutative operator graphs generated by reducible unitary representation of the Heisenberg-Weyl group
G. G. Amosov, A. S. Mokeev
We consider a reducible unitary representation of Heisenberg-Weyl group in a tensor product of two Hilbert spaces. A non-commutative operator graph generated by this representation…
On construction of anticliques for non-commutative operator graphs
G. G. Amosov, A. S. Mokeev
In this paper anticliques for non-commutative operator graphs generated by the generalized Pauli matrices are constructed. It is shown that application of entangled states for the…
