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…
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…
