Complex positive maps and quaternionic unitary evolution

Abstract

The complex projection of any n -dimensional quaternionic unitary dynamics defines a one-parameter positive semigroup dynamics. We show that the converse is also true, i.e. that any one-parameter positive semigroup dynamics of complex density matrices with maximal rank can be obtained as the complex projection of suitable quaternionic unitary dynamics.

Complex Projection of Quasianti-Hermitian Quaternionic Hamiltonian Dynamics

G. Scolarici

We characterize the subclass of quasianti-Hermitian quaternionic Hamiltonian dynamics such that their complex projections are one-parameter semigroup dynamics in the space of complex quasi-Hermitian density matrices.As an example, the complex projection of a spin-1 2 system in a constant quasianti-Hermitian quaternionic potential is considered.

Quaternionic versus complex maps

M. Asorey, G. Scolarici, Luigi Solombrino

We discuss the relation between completely positive quaternionic maps and the corresponding complex maps obtained via projection operation. In order to illustrate this formalism, we reobtain the (complex) qubit subdynamics of maximally entangled Bell states, as complex projection of unitary dynamics between quaternionic pure states.

Quasistationary quaternionic Hamiltonians and complex stochastic maps

G. Scolarici, L. Solombrino

We show that the complex projections of time-dependent η-quasianti-Hermitian quaternionic Hamiltonian dynamics are complex stochastic dynamics in the space of complex quasi-Hermitian density matrices if and only if a quasistationarity condition is fulfilled, i. e., if and only if η is an Hermitian positive time-independent complex operator. An example is also discussed. 1

Complex projection of unitary dynamics of quaternionic pure states

M. Asorey, G. Scolarici, Luigi Solombrino

Quaternionic quantum mechanics has been revealed to be a very useful framework to describe quantum phenomena. In the case of two qubit compound systems we show that the complex projection of quaternionic pure states and quaternionic unitary maps permits the description of interesting phenomena such as decoherence and optimal entanglement generation. The approach, however, presents severe limitations for the case of multipartite or higher dimensional bipartite quantum systems as we point out.

A resolution of quantum dynamical semigroups

Anilesh Mohari

We consider a class of quantum dissipative systems governed by a one parameter completely positive maps on a von-Neumann algebra. We introduce a notion of recurrent and metastable projections for the dynamics and prove that the unit operator can be decomposed into orthogonal projections where each projections are recurrent or metastable for the dynamics.
