Pure Stationary States of non-Hamiltonian and Dissipative Quantum Systems
Vasily E. Tarasov
Using Liouville space and superoperator formalism we consider pure stationary states of open and dissipative quantum systems. We discuss stationary states of open quantum systems,…
Quantum Computation by Quantum Operations on Mixed States
Vasily E. Tarasov
Usually models for quantum computations deal with unitary gates on pure states. In this paper we generalize the usual model. We consider a model of quantum computations in which th…
Open n-Qubit System as a Quantum Computer with Four-Valued Logic
Vasily E. Tarasov
In this paper we generalize the usual model of quantum computer to a model in which the state is an operator of density matrix and the gates are general superoperators (quantum ope…
On differential spectra in the reaction in the nearthreshold region
V. P. Chernyshev, P. V. Fedorets, A. E. Kudryavtsev +1
The differential spectra in the reaction for different reasonable versions of the production amplitude are discussed at the initial proton energy …
Quantization of Non-Hamiltonian Systems
Vasily E. Tarasov
In this paper a generalization of Weyl quantization which maps a dynamical operator in a function space to a dynamical superoperator in an operator space is suggested. Quantization…
Strings and Dissipative Mechanics
Vasily E. Tarasov
Noncritical strings in the "coupling constant" phase space and bosonic string in the affine-metric curved space are dissipative systems. But the quantum descriptions of the dissipa…
